Abstract:

Luffa spp. is an important worldwide cultivated vegetable and medicinal plant from the Cucurbitaceae family. In this study, we report a high-quality chromosome-level genome of the high-generation inbred line SG261 of Luffa acutangula. The genomic sequence was determined by PacBio long reads, Hi-C sequencing reads, and 10× Genomics sequencing, with an assembly size of 739.82 Mb, contig N50 of 18.38 Mb, and scaffold N50 of 56.08 Mb. The genome of L. acutangula SG261 was predicted to contain 27,312 protein-coding genes and 72.56% repetitive sequences, of which long terminal repeats (LTRs) were an important form of repetitive sequences, accounting for 67.84% of the genome. Phylogenetic analysis reveals that L. acutangula evolved later than Luffa cylindrica, and Luffa is closely related to Momodica charantia. Comparing the genome of L. acutangula SG261 and L. cylindrica with PacBio data, 67,128 high-quality structural variations (SVs) and 55,978 presence-absence variations (PAVs) were identified in SG261, resulting in 2424 and 1094 genes with variation in the CDS region, respectively, and there are 287 identical genes affected by two different structural variation analyses. In addition, we found that the transcription factor FY (FLOWERING LOCUS Y) families had a large expansion in L. acutangula SG261 (flowering in the morning) compared to L. cylindrica (flowering in the afternoon), which may result in the early flowering time in L. acutangula SG261. This study provides valuable reference for the breeding of and pan-genome research into Luffa species.

Abstract:

The fruits of Luffa acutangula (ridge gourd) which belonging to family Cucurbitaceae are grown, harvested before maturity and is very popular in Asia. Ridge gourd as whole, seeds and dried crusts are all used for medicinal purposes. It is a healthy food and contains good amount of fiber, vitamins and minerals including Vitamin B2, Vitamin C, carotene, niacin, calcium, phosphorus, iron and small quantities of iodine and fluorine. It is reported to contain many phytochemicals such as flavonoids, saponins, luffangulin, sapogenin, oleanolic acid and cucurbitacin B. Ridge gourd peel, powder and its extracts showed slightly higher antioxygenic activity as compare to ridge gourd pulp powder and its extracts. This may be attributed to the presence of higher amounts of phenolics and flavonoids which have been reported as potential antioxidants. Ridge gourd and there peel have potential to act as a functional food and a source of useful drugs because of the presence of various phytochemical components. L. acutangula has been used extensively in Indian traditional system of medicines as diuretic, expectorant, laxative, purgative, hypoglycemic agent and bitter headache agent and bitter tonic. The present review work focused on its botanical characters, ethnobotanical uses, nutritional value, phytochemical constituents and medicinal properties of L. acutangula.

Abstract:

Luffa is a genus of tropical and subtropical vines in the Cucurbitaceae family, recognized as an important cultivated commercial vegetable. However, the seeds of the luffa species are considered hard-seeded, and the processes governing seed germination remain understudied. The 9-cis-epoxycarotenoid dioxygenase (NCED) genes, which are critical for seed germination, have not been well characterized in Luffa. In this study, we identified four LaNCED genes in Luffa acutangula and four LcNCED genes in Luffa cylindrica, distributed across four chromosomes in each species. Phylogenetic analysis classified these genes into two subgroups. Gene structure and motif composition analyses revealed both similarities and differences among the NCEDs. Cis-element analysis further revealed that these NCEDs may be involved in growth regulation by modulating the phytohormonal network and responding to stress stimuli. Expression profiling of LcNCED genes during seed germination showed a decrease in LcNCED2 levels, coinciding with an increase in α-amylase activity throughout the germination process. Subcellular localization assays demonstrated that LcNCED2 is localized in the chloroplast. Furthermore, transient overexpression of LcNCED2 in tobacco leaves led to a significant increase in ABA content. Our findings provide a comprehensive genomic characterization of the NCED family in Luffa cylindrica and Luffa acutangula and reveal the functional role of LcNCED2 in regulating ABA levels, which may play a critical role in seed germination.

Abstract:

The value of Luffa acutangula, a species of the melon family, Curcubitaceae as food diminished as the fruit matured. They are then disposed as industrial or domestic waste material. However, the fibers of the matured fruits, also known as lignocelluloses fibers have high mechanical strength and can be used as reinforcing fillers for polymers. In this present study, treated and untreated fibers of Luffa acutangula were loaded as fillers for polypropylene (PP) at 1%, 3% and 5% loading. PP fiber composites loaded with alkali-treated fibers showed lower tensile and impact strength compared to PP fiber composites with untreated fibers. Thermal analysis of the fibers showed that alkali-treated fibers were deprived of the lignin content present in untreated fiber. This led to the lower mechanical properties of the alkali-treated luffa-filled PP composites as compared to its untreated counterpart. Increasing the fiber loading of the composites, increased the tensile and impact strength of untreated luffa-filled PP but decreased the tensile and impact strength of alkali-treated luffa-filled PP. This is in accordance to the removal of the lignin component upon alkali treatment which acts as a strengthening as well as energy absorption component of the fiber.

Abstract:

Information on genetic relatedness among ridge gourd (Luffa acutangula) genotypes from Bangladesh is currently not reported. Twenty eight accessions collected from different parts of Bangladesh were studied using random amplified polymorphic DNA (RAPD) technique. Four selected decamer primers, out of sixteen screened, could generate a total of 27 RAPD fragments of which 22 were polymorphic (81.5%). The bands ranged from 50 to 1500 bp in size. Genetic variation statistics for all loci estimated the average gene diversity (h) value as 0.278 and the Shannon’s Information Index (I) as 0.415. Dendrogram based on unweighted pair-group method with arithmetic averages (UPGMA) segregated the accessions into five clusters. Cluster III was the largest with 13 members followed by cluster II, V, I and IV with 6, 4, 3 and 2 members, respectively. Accession LA27 and LA29 were found very close to each other with the highest inter-variety similarity index (96.05%) and the lowest genetic distance (0.077); whereas accession LA40 and LA72 were more distant to each other with the lowest inter-variety similarity index (44.43%) and the highest genetic distance (0.73). A DNA extraction method has been standardized. The marker was found to be useful tool for assessing genetic variations in Luffa acutangula.

Abstract:

Luffa acutangula and Luffa cylindrica are popular vines belonging to the Cucurbitaceae family. They are extensively used as vegetables across the globe. Cucurbitaceae plants have played a major role in Indian medicinal systems and ethnopharmacology. Various plant parts have pharmacological properties viz. antioxidant, antiinflammation, antidiarrheal, anticancer, antiulcer and so on. These properties are due to phytochemicals present in the plants. Phytochemistry is the study of plant chemicals, particularly secondary metabolites. These metabolites are typically produced as a self-defence mechanism against insects, pests, pathogens, herbivores, ultraviolet exposure, and environmental hazards. The present study is aimed to identify and quantify certain phytochemicals which are known to be responsible for bioactivities. Peels are generally thrown away in culinary practice, but they are highly rich in phytochemicals. Peels of both plants have taken for the study and qualitative analysis of phytochemicals such as alkaloids, phenols, flavonoids, sterols, tannins, saponins, etc. were carried out. Plant extracts of different solvents were compared for antioxidant potential as well as total phenols and total flavonoids. Quantification of phenols and flavonoids was carried out as they are reported to have antioxidant potential. FRAP assay was performed to check the capacity of plant extract to scavenge free radicals. The correlation of phenols and flavonoids was carried out with antioxidant results to establish the fact. The plant extracts' total phenolic content was 66-357 mg gallic acid equivalent. The highest flavonoid content was found in methanol extracts of L. acutangula and L. cylindrica with values of 133.450 and 126.132 mg quercetin equivalent. FRAP assay concluded that methanol extracts of both plants have highest reducing power. TPC and TFC have shown strong positive correlation with FRAP assay. The phytochemicals and antioxidant potential of L. acutangula and L. cylindrica state that they possess valuable nutraceuticals. The pharmacological potential of the plants should be explored to maximum potential.

Abstract:

Background: Luffa acutangula has good anti-inflammatory and antioxidant activity. Ulcerative colitis has inflamed intestinal mucosal lining with frequent diarrhoea, mucosal, and bloody stools. The rectal administration provides high bioavailability, rapid absorption, and instant therapeutic effect. Conventional rectal formulations may be painful, while insertion and discomfort may also be experienced from the rectum leakage. Methodology: Luffa acutangula fruit extract was used for the preparation a novel rectal mucoadhesive in situ-gel by using thermosensitive polymers such as Poloxamer 407, Poloxamer 188. HPMC K4M and carbopol 940 are two mucoadhesive polymers that are used to boost the mucoadhesive force and gel strength. The response surface method design was used to optimize the formulation. The formulated in situ gel batches were analysed by gelation temperature, gel strength, gelling ability, gelling time, viscosity and in vitro drug release and mucoadhesive strength. Results and Discussion: The concentration of poloxamer 407 (15%) and poloxamer 188 (3%) was optimized by design expert. The optimized formulation F10 showed 36.35±0.890 gelation temperature and 94.66±0.57 % cumulative drug release. Drug release kinetics follows Higuchi release model and according to Korsemeyer Peppa's model value of n= 1.1114 indicates supercase -II transport. Gelation temperature of mucoadhesive in situ gel (F10HP2) was found in the range 36.45±0.102°C with 91.37±0.84 % cumulative drug release. Mucoadhesive in situ gel was tested in rat model of ulcerative colitis for 7 days. Conclusion: Preclinical study of optimized formulation shows that Luffa acutangula fruit extract can stop or prevent further progression of acetic acid induced ulcerative colitis in rat model.

Abstract:

Luffa acutangula or ridge gourd generally produces solitary and ribbed or ridged fruit, but Satputia a feral form of ridge gourd with hermaphrodite sex form produces non-ribbed fruits in cluster. The present study was conducted to determine the inheritance cluster bearing habit and non-ridge fruit in ridge gourd from the crosses of two hermaphrodite lines (Satputia Long and Satputia Small) which produced small numerous non-ribbed fruits in cluster and five monoecious lines (DRG-2, Pusa Nasdar, Utkal Tripti, Arka Summet and HARG-110), produced solitary long fruit with ten prominent ridges. It was observed that all the F1 plants were solitary bearer and produced ridged fruit. In F2 generation, the observed distribution of plant phenotypes for bearing habit and fruit surface morphology fitted well to the expected ratio of 3:1 (solitary vs cluster) and 15:1 (ridge vs non-ridge) for bearing habit and fruit surface morphology, respectively. The segregation pattern suggested monogenic recessive control of cluster bearing habit, while duplicate recessive genes control ridged fruit surface in Luffa acutangula.

Abstract:

Begomovirus was reported as one of the most aggressive and destructive viruses on several commercial crops, including cucurbits in Indonesia. Plants that infected with Begomovirus show the mosaic symptom on the leaves, change in leaf shape, stunts, change in color and shape of fruit. It was recently observed in cultivated angled luffa [Luffa acutangula (L.) Roxb] around Yogyakarta and Central Java. The aim of this research was to identify the virus by using Polymerase chain reaction (PCR). The result of Begomovirus amplification from the total DNA samples amplification using primer Krusty-Homer showed that DNA of Begomovirus from angled luffa was amplified at ~580bp. The DNA sequencing of angled luffa’s leaf isolate GD1 had 97.8% homology with SCLV-China isolate MC1. However, amplification of DNA seed samples using the same primer showed negative result. It was concluded that Begomovirus was not a seed borne virus. This is the first molecular report on the occurence of Begomovirus in angled luffa in Yogyakarta.

Full text

Abstract:

Luffa (Luffa acutangula) serves as an important edible, medicinal, and industrial crop. Sucrose synthase (SUS, EC 2.4.1.13) catalyzes sucrose metabolism and facilitates the entry of photosynthetically derived sucrose into metabolic pathways, playing crucial roles in plant growth, development, and stress responses. However, systematic investigations on the SUS gene family in luffa remain relatively scarce. In this study, we identified nine LaSUS family members distributed unevenly across six chromosomes. Their physicochemical properties and evolutionary relationships were systematically elucidated using bioinformatics tools. RNA-seq analysis revealed distinct expression patterns of LaSUS genes during luffa fruit aging, with most genes showing significant down-regulation during this process. Notably, several genes exhibited significant correlations with sucrose content during fruit aging. RT-qPCR analysis demonstrated the drought stress responsiveness of LaSUS genes, with LaSUS1 showing marked up-regulation under drought conditions. Furthermore, overexpression experiments in tobacco confirmed that LaSUS1 contributed to sugar accumulation, increased antioxidant enzyme activities, and positively regulated drought tolerance in luffa. This comprehensive study not only characterizes the LaSUS gene family and bridges the research gap of SUS genes in luffa but also provides theoretical support for investigating the roles of SUS genes in fruit ripening and abiotic stress responses in luffa.

Abstract:

Ridge gourd (Luffa acutangula L.) is a widely growing vegetative climber and used as a vegetable and traditional medicine. Ridge gourd is cross-pollinated crop and most of them are monoecious so that the description of the plants owned by each luffa accession is different. This study aims to determine the diversity between luffa accessions from different regions. The accessions used in this study were CB-LF 35, CB-LF 78, CB-LF 79, and CB-LF 98. The design used in this study was a Completely Randomized Design (CRD) with 4 luffa accessions as a treatment and 10 individuals from each of them as a replication. Observation of morphological characterization was carried out by observing qualitative character including plant vigor, stem shape, presence of tendrils, leaf color, leaf pubescense density, leaf shape, leaf lobes, and leaf edge. The morphological data obtained then compared between one accession to another accession. The results showed that the accessions of CB-LF 35, CB-LF 78, CB-LF 79 and CB-LF 98 had plant strength characters which were categorized as strong, angular stem shape, tendrils, green leaf color, a lot of trichome density, shape of the leaf are liver, and leaf lobe are classified into deep categories. The difference in character occurred in the leaf edge character with CB-LF 79 accession which had a toothed leaf edge character which are different from the other accessions namely CB-LF 35, CB-LF 78 and CB-LF 98 which had smooth leaf edge characters.

Abstract:

Anti-acne herbal formulations are used for the treatment of acne vulgaris with the added advantage of not producing adverse effects unlike synthetic drugs. Acne is an inflammatory skin disease that occurs due to blockages in polysebase and inflammation that are caused by bacteria. Topical and systemic antibiotics are always used for treatment of acne, but the gradual resistance to antibiotics can affect the success rate of acne cure. Medicinal plants play an important role in the development of potent therapeutic agents. Plant based drugs provide outstanding contribution to modern therapeutics as a source of many valuable secondary metabolites which serves as plant defence mechanisms against predator such as microorganism, insects and herbivores which have been proved to be potentially active compounds. There is a tremendous increase in search of antimicrobial plant extracts due to the fact that the resistance offered against antibiotic by the microorganism, in short the effective life span of any antibiotic is limited. Propionibacterium acnes are common pus-forming microbes responsible for the development of various forms of acne. In the present study anti-acne gels were prepared using polymer carbopol 940 along with the hydroalcoholic extracts of plants fruits of Luffa acutangula, leaves of Amaranthus spinosus and Morus alba and evaluated for their physicochemical properties, like pH, washability, extrudability, spreadability and viscosity. The formulations (PHG1-PHG6) were tested for the anti-acne activity by well diffusion method against Propionibacterium acnes. Results showed that the gels were non-irritant, stable and possess anti-acne activity. The efficacy when tested with a standard was almost same to that of Clintop (Marketed gel). This suggests that fruits of Luffa acutangula, leaves of Amaranthus spinosus and Morus alba have potential against acne causing bacteria and hence they can be used in topical anti-acne preparations and may address the antibiotic resistance of the bacteria. Keywords: Luffa acutangula, Amaranthus spinosus, Morus alba, Propionibacterium acnes, Acne vulgaris, Carbopol, Physicochemical properties.

Abstract:

The purpose of the present study was to formulate and evaluate Selegiline loaded bio-nanoparticles for effective treatment of Depression. For the preparation of bio-nanoparticles biomaterial was isolated from fruits of Luffa acutangula by an economic method. The biomaterial recovered from the concentrate was subjected for various physicochemical properties like color, solubility, color changing point and chemical test. Bio-nanoparticles were prepared by modified solvent evaporation method in different batches with variable drug/biomaterial ratio. Prepared batches were subjected for various evaluation studies like particle size, zeta potential, SEM, TEM, surface entrapment, in-vitro diffusion, DSC and stability. Particle size and zeta potential result revealed that all nanoformulation were within range of 110 to 152.7 with slight negative in charge. SEM and TEM study report indicate that formulations were spherical in shape with less or no aggregation. Less surface entrapment leads to better drug entrapped inside nanomatrix. Bio-nanoformulations were capable of releasing the drug in a slow sustained manner. From the present investigation, it may be concluded that biomaterial isolated from fruits of Luffa acutangula used in the preparation of bio-nanoparticle act as an efficient carriers for deliver selegiline at a controlled rate. It may significantly improve the ability to cross blood-brain barrier and serve as an effective tool to treat Depression disease.Goswami et al., International Current Pharmaceutical Journal, March 2016, 5(4): 33-37http://www.icpjonline.com/documents/Vol5Issue4/01.pdf

Abstract:

Telah dilakukan penelitian mengenai pengaruh stack berbahan organik terhadap perubahan suhu pada sistem pendingin termoakustik. Penelitian ini menggunakan dua jenis stack berbahan organik, yaitu batang padi dan gambas (luffa acutangula). Pada pendingin termoakustik gelombang berdiri, frekuensi resonansi mengalami pergeseran akibat keberadaan stack. Hasil yang diperoleh adalah perubahan suhu yang terjadi pada tandon panas dan dingin selama pengoperasian pendingin termoakustik. Untuk jenis bahan stack gambas dan batang padi memiliki panjang optimum sama, yaitu 8 cm dengan penurunan suhu masing-masing sebesar (11,7 ± 0,1) oC dan (8,1 ± 0,1) oC pada daya optimum 60 W.
