Abstract:
Orchid is a plant with a high aesthetic value.The existence of orchids directly by the community from their natural habitat, causing the existence of orchid in nature was threatened. The potential of orchid diversity in the Gebugan Nature Reserve area needs exploration to maintain its sustainability. This research would explore the diversity and abundance of orchid species and determined the environmental conditionof Gebugan Nature Reserve. The study was done on 2 stations with altitude difference are 900 m asl and 1045 m asl. Five plots of 10 m x 10 m were systematically constructed at each station with a distance of plots 50 meters. Species of orchids found in the Gebugan Nature Reserve were 12 species, including 11 species of epiphytic orchids and 1 species of terrestrial orchids. The abundance of individual orchid species was relatively higher in places with higher altitudes. Micropera sp was the most abundant orchid species and Corymborkis veratrifolia was the species of orchid with the lowest abundance. It is found that the environmental conditions of Gebugan Nature Reserve are suitable for orchid. The novelty of the research is providing a new data base of orchid in the Gebugan Nature Reserve. The result of the study would be beneficial for developing strategy of genetic conservation of orchird germplasm.

Abstract:
Long-term monitoring programs and population demographic models have shown that the population dynamics of orchids are to a large extent dependent on prevailing weather conditions, suggesting that the changes in climatic conditions can have far reaching effects on the population dynamics and hence the distribution of orchids. Although a better understanding of the effects of climate change on the distribution of plants has become increasingly important during the final years, only a few studies have investigated the effects of changing temperature and precipitation on the distribution of orchids. In this study, we investigated the impact of climate change on the distribution of four terrestrial orchid species (Orchis anthropophora, Orchis militaris, Orchis purpurea and Orchis simia). Using bioclimatic data for current and future climate scenarios, habitat suitability, range shifts and the impact of different abiotic factors on the range of each species were modelled using Maxent. The results revealed an increase in suitable habitat area for O. anthropophora, O. purpurea and O. simia under each RCP (Representative Concentration Pathway) scenario, while a decrease was observed for O. militaris. Furthermore, all four of the orchids showed a shift to higher latitudes under the three RCPs leading to a significant range extension under mild climate change. Under severe climate change, a significant decline in the distribution area at the warm edge of their distributions was observed. Overall, these results show that mild climate change may be beneficial for the studied orchid species and lead to range expansion. However, continued warming may yet prove detrimental, as all species also showed pronounced declines at lower latitudes when temperature increases were larger than 4 °C.

Abstract:
Nectarless flowers that deceive pollinators offer an opportunity to study asymmetric plant-insect interactions. Orchids are a widely used model for studying these interactions because they encompass several thousand species adopting deceptive pollination systems. High levels of intra-specific phenotypic variation have been reported in deceptive orchids, suggesting a reduced consistency of pollinator-mediated selection on their floral traits. Nevertheless, several studies report on widespread directional selection mediated by pollinators even in these deceptive orchids. In this study we test the hypothesis that the observed selection can fluctuate across years in strength and direction thus likely contributing to the phenotypic variability of this orchid group. We performed a three-year study estimating selection differentials and selection gradients for nine phenotypic traits involved in insect attraction in two Mediterranean orchid species, namely Orchis mascula and O. pauciflora, both relying on a well-described food-deceptive pollination strategy. We found weak directional selection and marginally significant selection gradients in the two investigated species with significant intra-specific differences in selection differentials across years. Our data do not link this variation with a specific environmental cause, but our results suggest that pollinator-mediated selection in food-deceptive orchids can change in strength and in direction over time. In perennial plants, such as orchids, different selection differentials in the same populations in different flowering seasons can contribute to the maintenance of phenotypic variation often reported in deceptive orchids.

Abstract:
Orchidaceae is one of the largest and the most widespread plant families with many species threatened with extinction. However, only about 1.5% of orchids’ genome sizes have been known so far. The aim of this study was to estimate the genome size of 15 species and one infraspecific taxon of endangered and protected orchids growing wild in Poland to assess their variability and develop additional criterion useful in orchid species identification and characterization. Flow cytometric genome size estimation revealed that investigated orchid species possessed intermediate, large, and very large genomes. The smallest 2C DNA content possessed Liparis loeselii (14.15 pg), while the largest Cypripedium calceolus (82.10 pg). It was confirmed that the genome size is characteristic to the subfamily. Additionally, for four species Epipactis albensis, Ophrys insectifera, Orchis mascula, Orchis militaris and one infraspecific taxon, Epipactis purpurata f. chlorophylla the 2C DNA content has been estimated for the first time. Genome size estimation by flow cytometry proved to be a useful auxiliary method for quick orchid species identification and characterization.

The article reports about chorology, phytocenotic, biotopical features of 24 orchid species (Orchidaceae Juss.) on the territory of Chernivtsi. The history of studying orchids in the city is described. The authors give the cadastre of locations of orchids based on studies of material at the herbariums (CHER, KW, LE, LW, МНА), literary sources and own collecting expeditions. There found 24 species of orchids in Chernivtsi. 6 of them (Anacamptis coriophora (L.) R.M. Bateman, Pridgeon et M.W. Chase s.l., A. palustris (Jacq.) R.M. Bateman, Pridgeon et M.W. Chase, Corallorhiza trífida Châtel., Dactylorhiza cordigera (Fries) Soó, Orchis purpurea Huds. та О. signifera Vest.) are not been confirmed by modern collecting expeditions, 3 of them (Anacamptis palustris, Orchis purpurea, О. signifera) were listed from herbarium and literary sources of the second half of ХІХ century. At the moment these species and their habitats are suspected to have been lost due to urban transformation. 17 species (70,8%) of orchids have been found in 1-5 habitats, and 7 species (29,2%) – in 6-20 habitats. Orchids are the part of 4 alliance 4 orders and 2 classes of natural vegetation Carpino-Fagetea sylvaticae Jakucs ex Passarge 1968 and Molinio-Arrhenatheretea Tx. 1937 and 5 types of habitats (4 of them are natural and 1 – synanthropic) on the territory of Chernivtsi. Natural plant communities with orchids belong to 4 habitats from Annex I of the Council Directive – 9130, 9170, 6510, 6440 and 4 biotopes listed in Resolution №4 of the Bern Convention – G1.6, G1.A1, E2.2, Е3.4. Remnants of natural forest biotopes having orchids were survived by the designation of landscape sanctuary – «Tsetsino» (430 ha) the object of national significance and «Haryachyy Urban» (108 ha) the object of regional significance. There are 11 and 2 species of orchids on the territory of «Tsetsinо» and «Haryachyy Urban» respectively. Cultivated coenosis of the biggest Park Architecture Monument of regional significance «Zhovtnevyy» (63,5 ha) have 3 speсies of orchids. 4 species are not protected. These results are important for follow-up monitoring measures on rare species of plants in Chernivtsi.

Abstract:
Indonesia is a tropical country that has natural forests and is suitable for orchid species habitat, leading to more than 5,000 species of orchids grow. The tropical area is the main distribution centre for epiphytic orchids, one of which is Dendrobium, which grows more than 1,000 species throughout the world. Orchid seeds are very small and do not have an endosperm, making germination difficult in their natural habitat. Mycorrhizal association with orchids plays a role in the survival of orchids in nature through seed germination and growth. This study aims to provide a deeper understanding about the important role of mycorrhiza in seed germination and growth of Dendrobium. The mechanism of mycorrhizal association with orchids begins with the initial contact of the fungus with the orchid, hyphae enter the cortex cells to form peloton, peloton lysis, and exchange of nutrients occurs. Orchid mycorrhiza that mostly found groups in Dendrobium are Rhizoctonia (Epulorhiza, Tulasnella, Rhizoctonia). Mycorrhiza plays a role in increased secretion of phytohormone and enzyme activity which supports seed germination and growth of orchids. Specific mycorrhizal data on orchids can be used as an effort for in-situ and ex-situ conservation of Indonesian orchids, including Dendrobium.

Abstract:
Phalaenopsis (Phal.) orchids including white, yellow, and purple flowers are some of the most important commercial orchids worldwide. These flowering plants can be considered to be promising sources of antioxidants since several medicinal orchids were shown to have potential antioxidant activities. The antioxidant activities and several secondary metabolite compounds of the methanolic extracts of four parts (the root, pedicel, leaf, and flower) of three hybrids of white (Phal. ‘City More’), yellow (Phal. ‘Sogo Meili’), and purple (Phal. ‘Queen Beer’) flowering orchids were investigated. Results showed that the highest levels of chlorophyll a and chlorophyll b were respectively obtained in leaf extracts of white and purple orchids, whereas carotenoid showed the highest content in the flower extract of the yellow orchid. Among all tested extracts, flavonoids and anthocyanin demonstrated the highest levels in the flower extract of the purple orchid, whereas the highest level of polyphenols was observed in the flower extract of the yellow orchid. The leaf extract of the white orchid was the most effective extract with a 50% inhibitory concentration in the DPPH-scavenging activity assay, while the highest ferrous iron-chelating effect was observed in flower extracts of the yellow orchid and purple orchid, and the pedicel extract of the purple orchid. In the reducing power assay, the flower extract of the white orchid showed the most potent extract, followed by the leaf extract of the yellow orchid and the flower extract of the purple orchid. Relationships between flower colors and antioxidant activities of these orchids showed them to be potential sources of antioxidants for both medicinal use and stress-tolerance in these orchids.

Abstract:
According to the results of the study, 14 species of orchids were found in the flora of the southern Altai in2019, which is 52 % of the species diversity of the Orchid flora of Kazakhstan. It is established that the coenopopulationsof orchids in the region develop and exist within the boundaries of specific phytocenoses and are characterized by a certainecological and phytocenotic amplitude of the development of natural environment conditions. They are distributed in thelower, middle and upper mountain zones. The widest altitude range is typical for species from the genus Dactylorchiza(absolute altitude 462–1365 m). In terms of life forms, species with a stem-like tuberoid (genera Dactylorhiza, Herminium,Orchis) predominate, while short-rooted and long-rooted species (genera Cypripedium, Epipactis) are less represented. InKaton-Karagai district, 10 species of orchids were recorded growing in 19 cenopopulations, in Kurchum – 5 species in 6cenopopulations. Vegetation cover in habitats is formed from 35 to 90 %. Due to the weak competition of orchids, theirshare in the addition of phytocenoses does not exceed 2 %.

Abstract:
This review summarises scientific knowledge concerning the mycorrhizal associations, pollination, demographics, genetics and evolution of Australian terrestrial orchids relevant to conservation. The orchid family is highly diverse in Western Australia (WA), with over 400 recognised taxa of which 76 are Declared Rare or Priority Flora. Major threats to rare orchids in WA include habitat loss, salinity, feral animals and drought. These threats require science-based recovery actions resulting from collaborations between universities, government agencies and community groups. Fungal identification by DNA-based methods in combination with compatibility testing by germination assays has revealed a complex picture of orchid–fungus diversity and specificity. The majority of rare and common WA orchids studied have highly specific mycorrhizal associations with fungi in the Rhizoctonia alliance, but some associate with a wider diversity of fungi. These fungi may be a key factor influencing the distribution of orchids and their presence can be tested by orchid seed bait bioassays. These bioassays show that mycorrhizal fungi are concentrated in coarse organic matter that may be depleted in some habitats (e.g. by frequent fire). Mycorrhizal fungi also allow efficient propagation of terrestrial orchids for reintroduction into natural habitats and for bioassays to test habitat quality. Four categories of WA orchids are defined by the following pollination strategies: (i) nectar-producing flowers with diverse pollinators, (ii) non-rewarding flowers that mimic other plants, (iii) winter-flowering orchids that attract fungus-feeding insects and (iv) sexually deceptive orchids with relatively specific pollinators. An exceptionally high proportion of WA orchids have specific insect pollinators. Bioassays testing orchid-pollinator specificity can define habitats and separate closely related species. Other research has revealed the chemical basis for insect attraction to orchids and the ecological consequences of deceptive pollination. Genetic studies have revealed that the structure of orchid populations is influenced by pollination, seed dispersal, reproductive isolation and hybridisation. Long-term demographic studies determine the viability of orchid populations, estimate rates of transition between seedling, flowering, non-flowering and dormant states and reveal factors, such as grazing and competition, that result in declining populations. It is difficult to define potential new habitats for rare orchids because of their specific relationships with fungi and insects. An understanding of all three dimensions of orchid habitat requirements can be provided by bioassays with seed baits for fungi, flowers for insects and transplanted seedlings for orchid demography. The majority of both rare and common WA orchids have highly specific associations with pollinating insects and mycorrhizal fungi, suggesting that evolution has favoured increasing specificity in these relationships in the ancient landscapes of WA.

Abstract Orchis purpurea Huds. is protected species both in the Czech Republic and Poland. In 2014 a new locality was found in Kojkovice (district Třinec) in the Cieszyn Foothils near border with Poland. The only one blooming individual was observed in 2014 and 2015 but it was accompanied by other 6 orchid species, that were much more abundant, as: Orchis pallens, Orchis mascula subsp. signifera, Listera ovata, Platanthera bifolia, Cephalanthera damasonium, Neottia nidus-avis. The Kojkovice forest deserves to be protected area due to abundant occurrence of many orchids.

Abstract:
Many orchids are rare and endangered due to habitat loss, degradation and human interference. This thesis aims to improve our understanding of orchid-mycorrhiza relationships and optimise methods for successful in vitro germination and development of terrestrial and epiphytic orchids. The research undertaken advances our understanding of orchids and has applications for conservation and horticulture. Fungal specificity plays a key role in orchid distribution and the colonisation of habitats. This was investigated in the Australian terrestrial orchid, Microtis media R. Br. in Chapter 2. Experiments demonstrated low fungal specificity in germination in vitro, although later development was more specific, with one fungus inducing protocorm development through to adult plants. Fungal compatibility was tested in several Eurasian terrestrial orchids in Chapter 3. Varying degrees of specificity were observed, with Anacamptis morio (L.) R.M.Bateman, Pridgeon & M.W.Chase and Dactylorhiza incarnata (L.) Soό displaying low fungal specificity whereas Serapias spp. were more specific. Orchids are commonly propagated without fungi using asymbiotic media. Asymbiotic and symbiotic methods were compared in two Eurasian terrestrial orchids in Chapter 4. In both cases, symbiotic methods resulted in higher germination and development. In Anacamptis laxiflora (Lam.) R. M. Bateman, Pridgeon & M. W. Chase, successful seedling establishment ex vitro was only achieved with symbiotic seedlings. Following this study, the effect of substrate rugosity and complexity on germination in asymbiotic and symbiotic culture of two Eurasian terrestrial orchids was investigated in Chapter 5. Substrate rugosity had a positive effect on germination and development in symbiotic cultures of A. morio and both asymbiotic and symbiotic cultures of Dactylorhiza purpurella (T.Stephenson & T.A.Stephenson) Soó. The subtribe Pleurothallidinae is one of the largest in the Orchidaceae and little is known about their propagation requirements. A number species from different genera within this group were tested with different asymbiotic media and fungi isolated from plants in an ex situ collection in Chapter 6. Germination was highest with two fungal strains but development of plantlets only occurred on asymbiotic media. Ex situ study and propagation of myco-heterotrophic orchids poses some difficulties. A novel method is presented, using microcosms for the initiation of tripartite symbioses with tree seedlings, fungi and orchids in Chapter 7. Associations between tree seedlings, fungi and orchid seed were observed. Germination was not achieved with seed of Neottia nidus-avis (L.) Rich. The method provides a basis for further development with applications in a range of ecological studies.

Abstract:
Genes responsible for differences in gene regulation and expression in normal cells and freezing tolerant cells were identified using two related wintergreen orchid species, Aplectrum hyemale and Tipularia discolor. Changes in gene expression observed in field-collected tissues obtained from different seasons were compared as were changes observed in plants subjected to cold shock in a laboratory environmental chamber. In order to clone these differentially expressed genes which may confer photosynthesis cold tolerance, the recently developed technique, mRNA differential display was employed. Using this process, mRNA was isolated from the tissue and reverse transcribed to cDNAs, which were amplified using specific anchored 3' primers and various random 5' primers. The 50-100 bands resulting from specific primers were compared on denaturing polyacrylamide gels. Bands differently expressed were excised from the gel and purified. In the future, if partial sequence analysis indicates they may code important regulatory proteins, they will be used as probes to obtain full-length genes from a cDNA library for further characterization. This study provides an opportunity not only to obtain important regulatory genes in plants, but also to understand more about temperature regulated gene expression in orchids.

Abstract:
Currently the breeding of desirable traits in orchid flowers is a lengthy and unpredictable process. A shortened breeding time and a more direct method of introducing specific genetic characteristics could be achieved if more information were available on the specific genes responsible for flower characteristics. In order to identify some of these genes, the genetic relationships between a hybrid, Dendrobium Gatton 'Sunray', and the parent species bred to produce it, D. chrysotoxum Lindley and D. pu/che//um Lindley were examined.Ball State UniversityMuncie, IN 47306These results were supported by Restriction Fragment Length Polymorphisms (RFLPs) observed following amplification of the Internal Transcribed Spacer (ITS) regions of the rDNAs.In order to clone genes responsible for specific flower characteristics, mRNA differential display was performed using total RNA isolated from the leaves, immature flowers, and mature flowers of the hybrid orchid and its two parents. Bands unique to D. Gatton 'Sunray' flower tissue, which were common to the hybrid and a single parent, were excised from a denaturing acrylamide gel. Four of the bands, which represented expressed genes determining inherited flower characteristics, were re-amplified, cloned, and three were sequenced. Partial sequence information obtained for two of the clones was used to search the GenBank database for homologous genes. One of the clones had sequence homology to plant 26S ribosomal genes and the other clone was homologous to sequences encoding regulatory proteins active during development (for example, the human retinoblastoma susceptibility gene or the Caenorhabditis e/egans cosmid R06F6 containing a serine/threonine protein kinase gene).

Abstract:
Abstract In this study, a label-free detection approach for effective detection of the odontoglossum ringspot virus (ORSV) infected orchids has been developed. We used semiconductor fabrication process to fabricate 1,810 micro/nano hybrid structured sensing electrodes on a 8 inch reclaimed wafer. The self-assembled monolayer (SAM) process was then employed to sequentially modify the electrode surface with 11-mercaptoundecanoic acid (11-MUA), 1-ethyl-3-(3-dimethylaminopropyl)-carbodiimide (EDC)/ N-hydroxysuccinimide (NHS), anti-ORSV, and ORSV. EIS was conducted for the ORSV concentration detection. Experimental results demonstrated that the ORSV concentration in a virus infected orchid leaf could be effectively detected. When compared with the ELISA kit, our device possesses a wider linear detection range (0.5–50,000 ng/mL) and a higher sensitivity. The specificity of our device on ORSV detection was also confirmed. Our sensing device retains advantages, such as label-free, lower amounts of the antibody and target sample required, low detection time, and a wider linear detection range. Those results imply the feasibility of our sensing device in field applications.
