Conservation of Medicinal Orchids Been Accomplished with Orchids for Horticultural Editorial Purposes ORCHID CONSERVATION NEWS The Newsletter of the Orchid Specialist Group of the IUCN Species Survival Commission Issue 1 April 2015 Conservation of Medicinal Orchids been accomplished with orchids for horticultural Editorial purposes. As you will appreciate from the articles in this issue, There are many paths to species vulnerability that can orchids have traditional use as medicine in many parts lead to extinction. Overcollection for food, for medicine of our global community. We look forward to more or for horticulture are just a few of the many challenges community-based conservation projects and innovative to species survival. There are also random, destructive ideas to consider in the future. natural disasters such as earthquakes that struck Nepal on April 25, 2015. Each challenge impacts human and Marilyn H. S.

It might not take much to disrupt or exploit an ecosystem but it can equally be possible, given time, to recover a sustainable balance. There are many paths toward achieving sustainability. In Nepal, conservation initiatives have been developed from strong, compassionate leadership to further public awareness and education, community involvement, as well as in-situ and ex-situ methodologies. Bangladesh, particularly the south east part of the country, has a diverse plant community but some orchid species, once widely distributed, are being impacted by exploitation Nepal Photo: Bijaya Pant for medicinal use. Conservation measures such as tissue culture methodologies are suggested but standard protocols must be developed to ensure that diversity is Our orchid conservation effort in two maintained, that bioactivity across a species population community forests of central Nepal is assessed so that plants are available for a range of future uses.

Of the estimated 460 orchid species in Nepal, we have reported 96 species as having medicinal value (Pant and Raskoti, 2013; Medicinal Orchids of Nepal.) The Government of Nepal has handed over accessible forest areas as Community Forests to the Forest User Groups for management and sustainable use. In order to create community awareness and to develop Dendrobium crepidatum Bulbophyllum leopardianum conservation strategies for two community forests in central Nepal, we designed a study using these forests as Some of the blooming orchids in the study sites.

  • Tianma, Gastrodia Tuber)
    Chapter 13 Gastrodia elata Blume. 天麻 (Tianma, Gastrodia Tuber) Hui-Min Gao 13.1 Botanical Identity Tianma, the steamed and dried rhizome of Gastrodia elata Blume. (Orchid Family), is one of the most popular traditional Chinese medicines and a famous foodstuff in China. It was first recorded in Shen-nung-pen-tsao-ching as a high-grade drug and widely used for the treatment of headache, dizziness, vertigo, convulsion, hyper- tension and other neurodegenerative diseases [1]. The orchid G. elata, lacking green leaves and chlorophyll, is a saprophytic perennial herb and it grows in the glades or at the edge of forests in humid mountain areas with the altitude of 400– 3200 m. This species lives in symbiotic association with the honey mushroom (Armillariella mellea) and its whole growth cycle except for florescence, is in the underground [2]. The wild G. elata distributed in China’s southwest, northeast and central regions, and especially, the rhizomes collected in the western Guizhou, southern Sichuan and northeastern Yunnan are considered to be the genuine medicinal material with good prestige. Due to the increasing market demand, natural reserves of G. elata have drastically decreased and the species has been listed as rare and endangered one in China and even around the world. Since the 1970s, G. elata has been extensively cultivated in Shaanxi, Anhui, Sichuan, Guizhou and Yunnan, and to date, Lueyang in Shaanxi province, has become the biggest production base all over the country. The rhizome is harvested from early winter to late spring, washed clean imme- diately, steamed thoroughly, spread out and dried at a lower temperature.

Hence, their knowledge on epiphytes and parasites was found to be very limited, especially among the young generation of the tribes. The present study reported the use of 28 species (16 epiphytes and 12 parasites), which represent about 13.4% of the total epiphytes and parasites present in Kerala, and they are of valuable properties and uses and are used for curing or corrective measures for several diseases. Majority of the properties and uses recorded are first reports pertaining to these special groups of plants. A thorough investigation on the phytochemistry and therapeutic values of the bioactive compounds contained in these epiphytes and parasites would result in the discovery of new and valuable drugs of high potentials and of interest to the Nutraceutical and Pharmaceutical industries.

Chyliza vittata is known to utilize leaves, stems and underground parts of several leafy and leafl ess orchids. Compared to the well-recorded feeding habits of C. vittata in Europe, its feeding habits in Japan are poorly studied. Thus, further records of its host plants and the habits of its larvae in Japan are likely to reveal the similarities and differences in its feeding habits in Europe and Japan. The current study reports C. vittata feeding on the stems of the mycoheterotrophic orchid Yoania japonica in central Japan. This study also showed that in spite of the small size of Yoania its reproductive success is not severely reduced when infested with C. vittata, whereas the robust stems of Gastrodia elata, which is its main host plant in Japan, are thought to be a defence against infestation by C. vittata.

A HISTORY OF DISCOVERY, LUST AND WEALTH Nora Eugenia D. G. ANGHELESCU1, Annie BYGRAVE2, Mihaela I. GEORGESCU1, Sorina A. PETRA1, Florin TOMA1 1University of Agronomic Sciences and Veterinary Medicine of Bucharest, 59 Mărăști Blvd, District 1, Bucharest, Romania 2Self-employed, London, UK Corresponding author email: [email protected] Abstract Orchidaceae is the second largest families of flowering plants. There are approximately 900 orchid genera comprising between 28,000-32,000 species of orchids. The relationship between orchids and mankind is complex. The history of orchids’ discovery goes hand in hand with the history of humanity, encompassing discovery and adventure, witchcraft and magic, symbolism and occultism, addiction and sacrifice, lust and wealth. Historically, the Chinese were the first to cultivate orchids as medicinal plants, more than 4000 years ago. Gradually, records about orchids spread, reaching the Middle East and Europe. Around 300 B.C., Theophrastus named them for the first time orkhis. In 1737, Carl Linnaeus first used the word Orchidaceae to designate plants with similar features. The family name, Orchidaceae was fully established in 1789, by Antoine Laurent de Jussieu. In 1862, Charles Darwin published the first edition of his book, Fertilisation of Orchids. Darwin considered the adaptations of orchid flowers to their animal pollinators as being among the best examples of his idea of evolution through natural selection. Orchidology was on its way. During the 18th and the 19th centuries, orchids generated the notorious Orchid Fever where orchid-hunters turned the search for orchids into a frantic and obsessive hunt.

  • Phylogeny, Character Evolution and the Systematics of Psilochilus (Triphoreae)
    THE PRIMITIVE EPIDENDROIDEAE (ORCHIDACEAE): PHYLOGENY, CHARACTER EVOLUTION AND THE SYSTEMATICS OF PSILOCHILUS (TRIPHOREAE) A Dissertation Presented in Partial Fulfillment of the Requirements for The Degree Doctor of Philosophy in the Graduate School of the Ohio State University By Erik Paul Rothacker, M.Sc. ***** The Ohio State University 2007 Doctoral Dissertation Committee: Approved by Dr. John V. Freudenstein, Adviser Dr. John Wenzel ________________________________ Dr. Andrea Wolfe Adviser Evolution, Ecology and Organismal Biology Graduate Program COPYRIGHT ERIK PAUL ROTHACKER 2007 ABSTRACT Considering the significance of the basal Epidendroideae in understanding patterns of morphological evolution within the subfamily, it is surprising that no fully resolved hypothesis of historical relationships has been presented for these orchids. This is the first study to improve both taxon and character sampling. The phylogenetic study of the basal Epidendroideae consisted of two components, molecular and morphological. A molecular phylogeny using three loci representing each of the plant genomes including gap characters is presented for the basal Epidendroideae. Here we find Neottieae sister to Palmorchis at the base of the Epidendroideae, followed by Triphoreae. Tropidieae and Sobralieae form a clade, however the relationship between these, Nervilieae and the advanced Epidendroids has not been resolved. A morphological matrix of 40 taxa and 30 characters was constructed and a phylogenetic analysis was performed. The results support many of the traditional views of tribal composition, but do not fully resolve relationships among many of the tribes. A robust hypothesis of relationships is presented based on the results of a total evidence analysis using three molecular loci, gap characters and morphology. Palmorchis is placed at the base of the tree, sister to Neottieae, followed successively by Triphoreae sister to Epipogium, then Sobralieae.

  • Transcriptome Analysis Reveals Underlying Immune Response Mechanism of Fungal (Penicillium Oxalicum) Disease in Gastrodia Elata Bl
    Wang et al. BMC Plant Biology (2020) 20:445 https://doi.org/10.1186/s12870-020-02653-4 RESEARCH ARTICLE Open Access Transcriptome analysis reveals underlying immune response mechanism of fungal (Penicillium oxalicum) disease in Gastrodia elata Bl. f. glauca S. chow (Orchidaceae) Yanhua Wang, Yugang Gao*, Pu Zang and Yue Xu Abstract Background: Gastrodia elata Bl. f. glauca S. Chow is a medicinal plant. G. elata f. glauca is unavoidably infected by pathogens in their growth process. In previous work, we have successfully isolated and identified Penicillium oxalicum from fungal diseased tubers of G. elata f. glauca. As a widespread epidemic, this fungal disease seriously affected the yield and quality of G. elata f. glauca. We speculate that the healthy G. elata F. glauca might carry resistance genes, which can resist against fungal disease. In this study, healthy and fungal diseased mature tubers of G. elata f. glauca from Changbai Mountain area were used as experimental materials to help us find potential resistance genes against the fungal disease. Results: A total of 7540 differentially expressed Unigenes (DEGs) were identified (FDR < 0.01, log2FC > 2). The current study screened 10 potential resistance genes. They were attached to transcription factors (TFs) in plant hormone signal transduction pathway and plant pathogen interaction pathway, including WRKY22, GH3, TIFY/JAZ, ERF1, WRKY33, TGA. In addition, four of these genes were closely related to jasmonic acid signaling pathway. Conclusions: The immune response mechanism of fungal disease in G. elata f. glauca is a complex biological process, involving plant hormones such as ethylene, jasmonic acid, salicylic acid and disease-resistant transcription factors such as WRKY, TGA.
