Abstract:

AbstractHow did one man living on an island come to acquire information about the rest of the vast archipelago? This article traces the inter-island information networks of Georg Everhard Rumphius (1627–1702), an employee of the Dutch East India Company, who was able to explore the natural world of the wider archipelago without ever leaving the Moluccan island of Ambon. This article demonstrates the complexities of Rumphius's inter-island networks, as he collected information about plants and objects from islands near and far. Using his administrative, commercial and household networks, Rumphius was able to interact with local actors from across the social spectrum, whose own active collection, mediation and circulation of objects and information overlapped with imperial activities in the archipelago. This article examines Rumphius as both a collector and a mediator, who negotiated between multiple economies of exchange and translated information from different islands for his distant European readership. Such practices of localized translation demonstrate how knowledge produced on one island was the product of criss-crossing inter-island networks, as the information concerned underwent its own complicated processes of transmission and transformation within the archipelago before reaching its intended audience in Europe.

Abstract:

In 1743, Georg Rumphius described a tree from the island of Seram in Herbarium Amboinense as Arbor Versicolor (now known as Eucalyptus deglupta Blume). Thus, the first European name for a species in the iconic Australian genus of Eucalyptus was coined decades before the British collected specimens in Australia, and before it was given its current name by a French botanist in 1789. The English translation of Rumphius’ description (see Supplementary Material) also includes vernacular names for Eucalyptus deglupta—some of many names applied to this species as it occurs from New Britain to Mindanao in the Philippines. While neither Rumphius’ name nor vernacular names for E. deglupta are recognised in current Western botanical nomenclature, the naming of Eucalyptus and other genera now recognised as Acacia, Casuarina and Melaleuca confirm the role of the eminent naturalist Rumphius in the history of Australian botany.

Abstract:

One of the most epic, fascinating but also tragic lives in the history of botany, is that of <strong>Georg Eberhard Rumphius (1627–1702)</strong>, known as the <strong><em>Merchant of Ambon</em></strong> or the <strong><em>Blind Sheer of Ambon</em></strong>. A remarkable man, in his life <strong><em>he played the roles of soldier, prisoner of war, mercenary, sailor, builder, merchant, physician, biologist, writer, illustrator and, above all, explorer</em></strong>. <strong>Rumphius</strong> is best known for his monumental achievement, <strong><em>Herbarium Amboinense</em></strong>, the first major record of the eastern Indonesian flora, describing and illustrating over a thousand new plants, including many orchid species. This seven-volume work had its own long and <strong><em>turbulent story</em></strong>, its publication delayed by earthquake, tsunami, fire, loss at sea and political embargo. Yet this <strong><em>masterpiece </em></strong>today stands as a model of excellent science done by a self-taught amateur.

Abstract:

The name Cancer saxatilis was used by Herbst (1785: 187, 188) for the translated description and cited figure of “Cancer saxatilis” from the pre-Linnaean work of Rumphius (1705: 9, 10, pl. 5, fig. M). Cancer saxatilis Herbst, 1875, is an available name as it fulfils the requirements of Articles 3–12 of the International Code of Zoological Nomenclature (hereafter the Code, ICZN 1999). The description and figure of “Cancer saxatilis” Rumphius (1705), and therefore Cancer saxatilis Herbst, 1785, are readily identifiable with Lophozozymus pictor (Fabricius, 1798) (see Ng & Chia 1995: 428).

Abstract:

Abstract Due to COVID-19, many scientists have to work remotely and have limited access to physical reference collections. This situation has highlighted that providing online digital content is considered one of the most effective solutions. To make materials of reference collection more accessible to scientists or researchers, we here report the Rumphius expeditions (1973 – 1980) materials to Indonesia that still remain at the Ambon Research Station or now become reference collection of Centre for Deep-Sea Research, LIPI-Ambon, Indonesia. The morphological analyses of fish, crustacea, and mollusc collected during the Rumphius expeditions revealed: 34 species from 23 different genera of fish; 21 species from 19 different genera of crustacea; and 60 species from 42 different genera of mollusc. This study demonstrates the value of reference collections as a resource in marine biology science and the important role of archivists in this current pandemic situation.

Abstract:

The early modern books on Ambonese natural history by G.E. Rumphius have mostly been analysed for their aesthetic form and scientific content. However, with the concept of contact zones as introduced by M.L. Pratt, these texts can also be read as historical sources about colonialism and slavery in the late seventeenth-century Moluccas. This article explores the traces of colonialism and slavery in Rumphius’Ambonese Herbal(1740ff.) and theAmbonese Curiosity Cabinet(1705).

Abstract:

Artikel ini membahas kedudukan rempah-rempah sebagai bagian penting dari sejarah Indonesia dengan mengkajinya dari perspektif sejarah total. Komoditas seperti cengkeh dan pala yang dihasilkan di Kepulauan Maluku pada masa lalu pernah dihargai tinggi dalam ekonomi global. Eksplorasi pelayaran dari berbagai penjuru dunia demi mencari rempah-rempah lantas menciptakan “Jalur Rempah” yang menjadikan nusantara sebagai poros ekonomi global. Selain berpengaruh besar terhadap berbagai unsur kehidupan dalam lingkup global, eksplorasi rempah-rempah telah memicu temuan penting dalam bidang ilmu pengetahuan, mulai dari Itinerario karya kartografi oleh Jan Huygen van Linschoten hingga Herbarium Amboinense karya botanikal oleh Rumphius. Akan tetapi di balik itu, rempah-rempah memicu terjadinya praktik eksploitasi alam. Dengan menggunakan pendekatan sejarah total sebagaimana diterapkan oleh Fernand Braudel, artikel ini menyajikan hubungan sejarah, politik dagang, budaya, alam, dan ilmu pengetahuan di balik eksplorasi dan eksploitasi rempah-rempah di Nusantara. This article discusses spices as an important part of Indonesian history through the lens of total historical perspective. In the past, commodities such as cloves and nutmegs which grew in Moluccas Island have been highly valued in global economic trade. Sea voyage exploration from all over the world in quest of spices has created the “Spice Route” that makes nusantara became the axis of global economy. Besides very influential on so many aspects of life in global scope, the exploration of spices was also engendering the important discovery in scientific field ranging from from Itinerario, a cartographical work of Jan Huygen Linschoten to Herbarium Amboinense, a botanical work of Rumphius. Nevertheless, the exploration was also encourages the exploitation of nature. By applying total history approach as applied by Fernand Braudel, this article try to trace the connection of history, trade politics, culture, nature and science behind the story of exploration and exploitation of spices.

Abstract:

Marinus Anton Donk, born in pre‐Indonesia and resident during the last years of Dutch Colonial rule, fell heir to a history of mycological studies traceable to the 1600s. Rumphius, Juhnhuhn, Zollinger, von H??hnel, van Overeem, and Boedijn were some of his predecessors. He survived cruel treatment while under Japanese incarceration during World War II, to become Head of the Herbarium in Bogor (formerly Buitenzorg), Java. Indonesia. In middle age, he moved to the Rijksherbarium in the Netherlands and further established his reputation in the taxonomy and nomenclature of the Hymenomycetes, a large group of basidiomycetous fungi. He was lauded and feared by numerous mycologists before he died prematurely in 1972. Occasional contemporary (chiefly mycological) personalities are included here as well as personal Donk communications to others.

Isolation, identification, and characterization of mannanase, xylanase and cellulase producing indigenous marine bacteria have been conducted from total 20 isolates. Based on 16S rDNA sequence analysis, three potential isolates are obtained and identified as Bacillus subtilis (M8), Bacillus tequilensis (X4) and Bacillus cereus (C9). The potential strains M8, X4 and C9 can produce mannanase, xylanase and cellulase activities such as 9.5 U/mL; 0.36U/mL;0.56U/mL with optimum pH and temperature 6.0;50oC, 5.5;70oC and 8;50oC, respectively. Based on the TLC analysis, mannanase from M8 and xylanase from X4 has potential to hydrolyzed mannan and xylan for producing oligosaccharides with size around tri-hexasaccharides as a main product.

Abstract:

This study focuses on understanding the historical tsunami events in Eastern Indonesia, specifically the Banda Sea region, by extracting information from the limited and challenging-to-interpret historical records. The oldest detailed account of a tsunami in Indonesia dates back to 1674, documented in the book Waerachtigh Verhael Van de Schlickelijcke Aerdbebinge by Rumphius. The study aims to comprehend the primary source of the tsunami and analyze its characteristics to facilitate future tsunami risk reduction. The methodology includes collecting topography and bathymetry data, conducting landslide scenario analysis, employing a two-layer wave propagation model, and performing spectral analysis. The study utilizes comprehensive datasets, investigates potential landslide scenarios, simulates tsunami propagation, and analyzes frequency characteristics using the fast Fourier transform. The 1674 event yielded a runup height of approximately 50–100 m, whereas this study underestimated the actual runup. To illustrate the tsunami wave along the bay’s coastline, a Hovmöller diagram was employed. By analyzing the Hovmöller diagram, the power spectral density was computed, revealing five prominent period bands: 6.96, 5.16, 4.1, 3.75, and 3.36 min. The integration of these components provides a rigorous approach to understanding tsunami dynamics and enhancing risk assessment and mitigation in the study area.

Abstract:

The worldwide exchange of fruits has been facilitated by traders, travelers, sovereigns, conquerors, diplomats, missionaries, and botanists. The beginnings of organized plant exploration date to the Pharaohs of ancient Egypt, who, as early as 2000 bce, brought back exotic trees and plants in their foreign campaigns and illustrated them on their temple walls. Queen Hatshepsut (ca. 1500 bce) sent out ships to bring back trees from the land of Punt (northeast African coast). The exchange of plants throughout antiquity was a by-product of trade routes between East and West as well as though the campaigns of conquerors including Alexander, the warriors of Islam, Genghis Khan, and the crusades. The age of exploration starting at the end of the 15th century was inspired by the search for a sea route to the spice-rich East. The encounter of Columbus with the Americas brought about an explosive exchange of New World and Old World plants. The rise of science in the 17th and 18th centuries was associated with botanical exploration involving travels and expeditions, including Hans Sloan to the West Indies, James Cunningham to China, Georg Eberhard Rumpf (Rumphius) to the Moluccas, and Sir Joseph Banks to Newfoundland, Labrador, South America Tahiti, New Zealand, Australia, the Malay Archipelago, Hebrides, and Iceland.

Mohammed EI, Ali EA. 2017. Comparative study of crude and refined edible oils of sunflower and peanut. Biofarmasi (Rumphius J Nat Prod Biochem) 15: 1-4. The objective of this study was to compare crude and refined edible oils of sunflower and peanut from their physical properties like color, moisture, density and refractive index, and chemical properties like peroxide value, zero fatty acid, acid value, saponifiable and non-saponifiable value. For example, after refining process, the moisture content of sunflower oil was reduced from 0.07% to 0.02% and from 0.13% to 0.02% on peanut oil, the peroxide value of sunflower oil was decreased from 13.94 meq/kg to 2.77 meq/kg and from 3.137 meq/kg to 0.2 meq/kg on peanut oil. Gas chromatographic applied on sunflower oil showed that stearic acid area percentage was decreased from 0. 1.8805 to 0.3510 after refining, and for peanut oil, it was decreased from 11.1643 to 1.0281 after refining. This study showed marked differences in the physicochemical properties of sunflower and those of peanut. These properties of each crude oil were significantly changed when it was subjected to the refining process. Fatty acid components of both crude and refined were determined by GC. The study showed striking differences in the crude and refined oils from sunflower and peanut types.

Biofarmasi (Rumphius J Nat Prod Biochem) 15: 26-28. Side effect caused by condom with synthetic spermicide encourages researcher to find alternative spermicide from plant which have fewer side effects. Bark of durian extract is potential candidate for herbal spermicide because it could decrease the percentage of human spermatozoa quality in vitro at the concentrations of 2%. This study was designed to evaluate its spermicidal activity by in vitro on motility, velocity of movement, viability and morphology of human spermatozoa. The formulation of gel with 2% of bark of durian extract were developed by using hydroxypropyl methylcellulose as gelling agent with 3 different concentrations, namely, 1.5; 2; and 2.5 %. Evaluation of gel preparations including physical appearance, viscosity, spreadability, and pH was done to obtain the best formula. Based on the evaluation, the best performance of gel was achieved by adding 2% of HPMC. Furthermore, the spermicidal activity of the gel with bark of durian extract was tested and compared to the bark of durian extract without gel, gel without bark of durian extract, and the fresh sperm as control. Formulation of gel with bark of durian extract significantly decreased all parameters of spermatozoa quality. Thus, formula containing 2% of bark of durian extract with HPMC 2% possesses appreciable spermicidal potential.

Abstract:

<strong>Sea Cucumbers of Ambon Bay, Maluku.</strong> Research on the diversity of marine life in Indonesian waters, particularly in Ambon Bay, Maluku, had started in 1705 by G.E. Rumphius. In the period thereafter until the year 2000s there was a possibility in changes of environmental conditions or habitat in Ambon Bay waters. Therefore, a study on the status of marine life in the waters of Ambon Bay and surrounding areas needed to be done. The research aimed to inventory sea cucumbers in Ambon Bay, which was conducted in July–October 2009 at 12 research stations. The method used was a free hand picking collection using snorkeling and scuba equipment. The result showed 18 species of sea cucumbers, two species of which (Holothuria atra, Opheodesoma grisea) have a wide distribution and habitat preference since they found in four to five sampling stations. The results of this inventory coupled with the results of previous studies based on literatures from 1990 showed there were 46 species of sea cucumbers in Ambon Bay, which were about 13% of the estimated number of sea cucumber species in Indonesia (±350 species). Fluctuations in the number and composition of sea cucumber species that successfully inventoried during the period of 1990s to this study are discussed in detail in this paper. There is a possibility to obtain new records, even new species in this location, along with the increase of understanding in method selection and species identification. <br /><br />

Abstract:

Distinctive for its pungent and oftentimes rotten odor, the thorny fruit of durian (Durio spp.) is considered a delicacy throughout Asia. Despite its burgeoning global recognition, durian remains a fruit of contradiction—desirable to some yet repulsive to others. Although regarded commonly as immobile, mute, and insentient, plants such as durian communicate within their own bodies, between the same and different species, and between themselves and other life forms. As individuals and collectives, plants develop modes of language—or phytodialects—that are specific to certain contexts. Focused on vegetal semiosis or sign processes, a phytosemiotic lens views plants as dynamic and expressive subjects positioned within lifeworlds. Absent from phytosemiotic theory, however, are the cultural sign processes that take place within and between plants—what I call cultural phytosemiotics. The framework I propose calls attention to the interlinked biological, ecological, and cultural dimensions of signification between plants and non-plants. From a phytosemiotic standpoint, this article examines historical, cinematographic, and literary narratives of durian. Reflecting the fruit’s divisive sensory effects, historical accounts of Durio by Niccolò de’ Conti, Jan Huyghen van Linschoten, Georg Eberhard Rumphius, and William Marsden alternate between praise and disdain. Moreover, films such as Fruit Chan’s Durian Durian (2000) and Anthony Chen’s Wet Season (2019) narrativize the polarities that similarly figure into historical depictions of the species. Literary narratives, including the poems “Durians” (2005) by Hsien Min Toh and “Hurling a Durian” (2013) by Sally Wen Mao, investigate the language of durian’s olfactory and gustatory sensations. Along a continuum between adoration to revulsion, durian embodies the otherness of vegetal being. In an era of rampant biodiversity loss, learning to embrace botanical difference should be a human imperative.

Biofarmasi (Rumphius J Nat Prod Biochem) 15: 5-14. Bioremediation is the use of microbes to remove various contaminants from the environment. The present research work was carried out during 2014-15. Aspergillus niger, Aspergillus flavus and Penicillium spp. were employed for biodegradation of pesticides commonly used in Guyana. Initially, the fungi were screened for ligninolytic potential by observing decolorization/degradation of a synthetic dye (Remazol Brilliant blue) in PDA agar. The degradation of dyes was noted by the change in original colour of the dye and visual disappearance of colour from the fungustreated Petri plates. In addition, accumulation of the dye by the fungal mycelium was also noticed. The fungi were then tested for their tolerance to the pesticides Diuron, Malathion and Diazinon respectively. This was done on solid media using PDA agar with amoxillin to prevent bacterial growth. The pesticides were introduced to the fungi by way of disc diffusion. Discs of a known diameter were infused with the respective pesticides at different concentrations and placed at strategic points around the inoculated fungal mycelium. The extent of inhibition was measured by comparing the growth diameter in the sample verses growth in the control. The pesticide diazinon was found to have inhibited the fungi more when compared to Malathion and Diuron. Finally, the fungi were used to degrade the pesticides in a liquid culture-Peptone Broth. The pesticide Diuron was selected because the fungi thrived best in all concentrations of this pesticide. A concentration of the pesticide Diuron was place in flasks containing the peptone broth with mycelia discs of the respective fungal strain. The final concentration of the pesticide was determined by using High Performance Liquid Chromatography (HPLC). The concentration of the pesticide in each strain of fungi was decreased. Aspergillus niger was found to have the highest rate of pesticide degradation followed by Aspergillus flavus and Penicillium.

Biofarmasi (Rumphius J Nat Prod Biochem) 15: 29-43. In Kenya, microbial infections are a major cause of morbidity. The effectiveness of antibiotic is threatened by the increase of resistance of pathogenic microbes against most available drugs because new pathogens continue to emerge. Nowadays, herbal remedies offer hope since they are readily available and cheap. The aim of this research was to investigate the activity of antimicrobial, the lethality of brine shrimp and phytochemical composition of crude extracts of four selected plants namely Schrebera alata (Oleaceae), Ormocarpum kirkii (Papilionoideae), Helichrysum forskahlii (Asteraceae) and Cussonia holstii (Araliaceae) that are medicinally used by herbalists from Losho, Narok County Kenya for treatment of ear, nose and throat infections, gastrointestinal disorders and skin diseases. Qualitative antimicrobial susceptibility test against five microorganisms, methicillin-resistant Staphylococcus aureus, Bacillus cereus, Escherichia coli, Pseudomonas aeruginosa and Candida albicans was investigated using agar diffusion methods to produce inhibition zones and the data accrued were analyzed using Analysis of variance. Minimum inhibitory concentrations were determined by broth microdilution method. Toxicity of the extracts was analyzed using brine shrimp lethality assay. The median fatal concentration of fifty was determined by data analysis using Finneyâ€Ÿs computer program. Phytochemical screening for flavonoids, sterols, alkaloids, tannins, quinones and terpenoids and saponins was determined using standard procedures. The observation showed that the organic crude extracts of H. forskahlii had the highest inhibition zone against methicillin-resistant S. aureus of 19.5 and 18.5 mm in agar well and agar disk diffusion respectively. In addition, organic extracts of H. forskahlii showed the highest antifungal inhibition zone of 8.5 mm in agar well diffusion. Minimum values of inhibitory concentrations varied from 15.625 to 250 mg/mL. Organic crude extracts of H. forskahlii and C. holstii were found to be highly toxic with lethal concentration of 0.009 mg/mL. All plant crude extracts contained flavonoids, sterols, alkaloids, tannins, quinones, and terpenoids. Saponins were present in all the plant extracts except in organic extracts of H. forskahlii. This study promoted the first record of antimicrobial activity, toxicity and phytochemical composition of S. alata and C. holstii. The study has shown that H. forskahlii and O. kirkii possess promising antimicrobial activity against microbes of health importance and could lead to the isolation of new, safe and efficacious antimicrobial compounds. Further research should be carried on O. kirkii and S. alata to isolate and characterize the compounds responsible for the observed activity.

Abstract:

Tinospora rumphii (T. rumphii) is a folkloric medicinal plant that is widely distributed in Asia and Africa. It has been widely used by locals to treat many diseases including jaundice, which is a manifestation of liver damage. We investigated the action of T. rumphii crude extract together with zinc sulphate, a known tumor modulator, on hepatic injuries induced by intraperitoneal (i.p) injections of quinoline on albino mice. The hepatotoxic effect was assessed by bilirubin concentration in the blood serum, while the genotoxic effect was determined by single-cell gel electrophoresis (SCGE). The mice orally fed with the crude extracts, following quinoline exposure, had reduced serum bilirubin concentration and DNA damage. Mice treated with Zinc sulphate, on the other hand, had remarkably reduced DNA damage on hepatocytes. Our findings showed that hepatoprotective potential of T. rumphii extract is dose-dependent and that utilization of the extract as medicinal remedy must be strictly monitored, while zinc was proven to reverse genotoxic effect of quinoline. This study unraveled the potential of T. rumphii extract and zinc as important hepatoprotective agents for future treatment of hepatic damage caused by chemotherapeutic agents used in cancer treatment.

Abstract:

Abstract Diospyros rumphii (Ebony) is a high-value timber species native to Indonesia, which is listed as a Data Deficient species by the International Union for Conservation of Nature (IUCN) Red List of Threatened Species. Therefore, additional data to enrich knowledge on the distribution, ecology, and genetics of this species is urgently needed. Furthermore, this study aimed to generate whole-genome sequencing data, including the low-coverage data for D. rumphii using MinION Oxford Nanopore Technologies (ONT). The sequence data generated from leaf and cambium genomic DNA was assembled to result in a draft of the chloroplast genome and constructed the phylogenetic tree based on partial nucleotide sequences of the rbcL gene. The results showed that DNA sequencing of D. rumphii generated a 3.25 Gb of long-read sequences data and a draft of a partial chloroplast genome with a size of 150,578 bp. Genetic relationship analysis using the rbcL gene showed that D. rumphii was positioned in one clade with Diospyros oblonga, which has a bootstrap value of 87% suggesting that the rbcL gene can be considered as recommended molecular marker for genetic analysis of D. rumphii in the future.

Abstract:

This study aims to determine the effects of soil type on the phytochemical profiles (type and abundance) of Tinosphora rumphii stem ethanolic extract collected from Adtuyon Clay loam and hydrosol types of soil. The plant stem extract was concentrated using rotary evaporator until it is semi-solid in form. Phytochemical screening was done to evaluate the plant’s phytochemical constituents. Results showed the presence of alkaloids, flavonoids, steroids, and tannins in the T. rumphii extract obtained from two sites with Adtuyon Clay loam and hydrosol types of soil. On the other hand, saponins are present only in the plant sample obtained in Adtuyon type of soil. Results also revealed variations on the abundance of some phytochemicals present in T. rumphii stem collected from the two types of soil in which alkaloids and tannins are less in abundant in Adtuyon clay loam soil while high in abundance in hydrosol type. Hydrosol type of soil is effective in storing alkaloids and tannins in T. rumphii stem could be due to the presence of iron and manganese in Hydrosol type of soil that are necessary for accumulation of such phytochemicals in the plant tissues. On the other hand, Adtuyon clay loam soil is valuable in storing saponins.

Abstract:

In the present study, novel genomic-SSR (g-SSR) markers generated in our laboratory were used to characterize Tinospora cordifolia and related species. The g-SSR marker was also compared with EST-SSR and SCoT markers used earlier in our laboratory to assess the genetic diversity of T. cordifolia. A total of 26 accessions of T. cordifolia and 1 accession each of Tinospora rumphii and Tinospora sinensis were characterized using 65 novel g-SSR markers. A total of 125 alleles were detected with 49 polymorphic g-SSR markers. The number of alleles per locus varied from 1–4 with a mean value of 2.55 alleles per locus. Mean PIC, gene diversity, and heterozygosity were estimated to be 0.33, 0.41, and 0.65, respectively. The two species, namely T. rumphii and T. sinensis, showed cross-species transferability of g-SSRs developed in T. cordifolia. The success rate of cross-species transferability in T. rumphii was 95.3% and 93.8% in T. sinensis, proving the usefulness of this marker in genetic diversity studies of related species. The Tinospora accessions were also used for molecular characterization using SCoT and EST-SSR markers and compared for genetic diversity and cross-species transferability. The PIC, gene diversity, heterozygosity, and principal coordinate analysis showed that g-SSR is the better maker for a genetic diversity study of T. cordifolia. Additionally, high cross-species transferability of g-SSRs was found (95.3% and 93.8%) compared to EST-SSRs (68.8% and 67.7%) in T. rumphii and T. sinensis, respectively.

Abstract:

Background Sleeping sickness caused by Trypanosoma brucei rhodesiense is a fatal disease and endemic in Southern and Eastern Africa. There is an urgent need to develop novel diagnostic and control tools to achieve elimination of rhodesiense sleeping sickness which might be achieved through a better understanding of trypanosome gene expression and genetics using endemic isolates. Here, we describe transcriptome profiles and population structure of endemic T. b. rhodesiense isolates in human blood in Malawi. Methodology Blood samples of r-HAT cases from Nkhotakota and Rumphi foci were collected in PaxGene tubes for RNA extraction before initiation of r-HAT treatment. 100 million reads were obtained per sample, reads were initially mapped to the human genome reference GRCh38 using HiSat2 and then the unmapped reads were mapped against Trypanosoma brucei reference transcriptome (TriTrypDB54_TbruceiTREU927) using HiSat2. Differential gene expression analysis was done using the DeSeq2 package in R. SNP calling from reads that were mapped to the T. brucei genome was done using GATK in order to identify T.b. rhodesiense population structure. Results 24 samples were collected from r-HAT cases of which 8 were from Rumphi and 16 from Nkhotakota foci. The isolates from Nkhotakota were enriched with transcripts for cell cycle arrest and stumpy form markers, whereas isolates in Rumphi focus were enriched with transcripts for folate biosynthesis and antigenic variation pathways. These parasite focus-specific transcriptome profiles are consistent with the more virulent disease observed in Rumphi and a less symptomatic disease in Nkhotakota associated with the non-dividing stumpy form. Interestingly, the Malawi T.b. rhodesiense isolates expressed genes enriched for reduced cell proliferation compared to the Uganda T.b. rhodesiense isolates. PCA analysis using SNPs called from the RNAseq data showed that T. b. rhodesiense parasites from Nkhotakota are genetically distinct from those collected in Rumphi. Conclusion Our results suggest that the differences in disease presentation in the two foci is mainly driven by genetic differences in the parasites in the two major endemic foci of Rumphi and Nkhotakota rather than differences in the environment or host response.

Abstract:

The study deals with the distribution pattern and morphology of stomata and cystoliths in the leaves of six taxa of the genus Ficus of the family Moraceae in Arunachal Pradesh. All the plant species studied contained stomata and cystoliths, which vary in shape and size. Actinocytic stomata type was present in only one species (Ficus sp. 1). Anomocytic type in three, and paracytic in four species. Stomatal frequency calculation revealed that the highest frequency was reported in F. hispida and the lowest in F. rumphii. There is also an indication that semi-coriaceous and coriaceous glabrous leaved species of Ficus are linked to the stomatal characters. The results have shown the presence of stalks in all the cystoliths of various sizes. Different shapes such as star-shaped, bean-shaped, solitary, round, and oblong cystoliths are recorded during the study. The largest cystoliths were found in F. rumphii, where its spinous surface is quite distinct from all other species and can be recognized very easily. Cystoliths are found to occur on both sides of the epidermal layer in three species (F. religiosa, F. rumphii and Ficus sp.3) whereas, it was found in the upper epidermal layer in other species. Photographic details, along with a systematic key using the cystoliths characters were also established.

Abstract:

AbstractPolyalthia is one of the largest genera in the Annonaceae family, and has been widely used in folk medicine for the treatment of rheumatic fever, gastrointestinal ulcer, and generalized body pain. The present investigation reports on the extraction by hydrodistillation and the composition of the essential oils of four Polyalthia species (P. sumatrana, P. stenopetalla, P. cauliflora, and P. rumphii) growing in Malaysia. The chemical composition of these essential oils was determined by gas chromatography (GC-FID) and gas chromatography-mass spectrometry (GC-MS). The multivariate analysis was determined using principal component analysis (PCA) and hierarchical clustering analysis (HCA) methods. The results revealed that the studied essential oils are made up principally of bicyclogermacrene (18.8%), cis-calamenene (14.6%) and β-elemene (11.9%) for P. sumatrana; α-cadinol (13.0%) and δ-cadinene (10.2%) for P. stenopetalla; δ-elemene (38.1%) and β-cubebene (33.1%) for P. cauliflora; and finally germacrene D (33.3%) and bicyclogermacrene for P. rumphii. PCA score and HCA plots revealed that the essential oils were classified into three separated clusters of P. cauliflora (Cluster I), P. sumatrana (Cluster II), and P. stenopetalla, and P. rumphii (Cluster III) based on their characteristic chemical compositions. Our findings demonstrate that the essential oil could be useful for the characterization, pharmaceutical, and therapeutic applications of Polyalthia essential oil.

Abstract:

Pleurotomarioidea represents a truly isolated and basally diverging lineage in Vetigastropoda (Mollusca: Gastropoda) whose fossil record can date back to the late Cambrian, thus providing rare insights into the evolutionary history of molluscs. Here, we sequenced and assembled the complete mitochondrial genome of one representative species from Pleurotomarioidea—Entemnotrochus rumphii (Schepman, 1879)—of which the mitogenome is 15,795 bp in length, including 13 protein-coding genes, two ribosomal RNA genes, and 22 transfer RNA genes. The nucleotide composition was biased toward AT, and A + T content reached 65.2%. E. rumphii was recovered as sister to all other living vetigastropods according to mitogenome-based phylogenetic analysis. The mitochondrial gene order was consistent with major vetigastropods and the hypothetical ancestral gastropoda, suggesting the deep conservation of mitogenome arrangement in Vetigastropoda.

Abstract:

One of the important activities to achieve the implementation of REDD+ activities is the measurement and reporting of carbon stocks (Masripatin et.al. 2010). Information on the potential for carbon stocks in a plant stand or forest area can provide an overview for related parties of the potential carbon stocks and the added value that will be obtained if it maintains and develops a certain plant species to support the reduction of greenhouse gas emissions. This study aims to determine the potential of biomass, carbon stocks, and economic valuation of the carbon stocks potential of several Ebony stands contained in the Kawanua Arboretum BP2LHK Manado. The types of Ebony stands that were the object of this study were Dyospiros celebica, Dyospiros rumphii, and Dyospiros ebenum. Determination of biomass potential and carbon stocks using the allometric equation. The economic valuations of each potential carbon stocks of Ebony stands are obtained based on the selling value of carbon set by the World Bank Group. Based on the results of the study, it is known that the carbon stocks potential of each Ebony stand, namely Diospyros rumphii, is 74.246 tons/ha, followed by the potential carbon storage in the Diospyros celebica stand of 67.768 tons/ha and Diospyros ebenum of 64.977 tons / ha, while the economic valuation value of the highest carbon storage potential is found in the Diospyros rumphii stand of USD 148.492 followed by Diospyros celebica is USD 135.536 and Diospyros ebenum is USD 129.954
