Auxin response factor (ARF) proteins play roles in plant responses to diverse environmental stresses by binding specifically to the auxin response element in the promoters of target genes. Using our latest public Dendrobium transcriptomes, a comprehensive characterization and analysis of 14 DnARF genes were performed. Three selected DnARFs, including DnARF1, DnARF4, and DnARF6, were confirmed t...

Establishing an aseptic in vitro culture for Dendrobium, or for any plant in fact, is the most important step towards developing an effective in vitro tissue culture including micropropagation protocol. Success in initial aseptic culture will contribute to the successful production of in vitro cultures that may involve the initiation or formation of callus and/or protocorm-like bodies (PLBs), t...

In vitro propagation of Dendrobium macrostachyum, a threatened and endemic species was achieved through nodal explants. The nodal explants were cultured on Murashige and Skoog (MS) basal medium and MS medium supplemented with N6-benzyladenine (BA-2.22, 4.44 and 8.88 microM), Kinetin (KN-2.32, 4.65, and 9.29 microM) and Coconut water (CW, 5, 10 and 15%) individually or in combination with 2.69 m...

Dendrobium officinale is a precious traditional Chinese medicinal plant because of its abundant polysaccharides found in stems. We determined the composition of water-soluble polysaccharides and starch content in D. officinale stems. The extracted water-soluble polysaccharide content was as high as 35% (w/w). Analysis of the composition of monosaccharides showed that the water-soluble polysacch...

Orchids make up about 10% of all seed plant species, have great economical value, and are of specific scientific interest because of their renowned flowers and ecological adaptations. Here, we report the first draft genome sequence of a lithophytic orchid, Dendrobium catenatum. We predict 28,910 protein-coding genes, and find evidence of a whole genome duplication shared with Phalaenopsis. We o...

Two new records of Dendrobium, D. daklakense, and metrium, are reported for the flora Laos first time. Photographs, information on habitat ecology, vernacular names additional notes each species given based collections from Dak Cheung Plateau, Sekong Province (D. daklakense), Phou Khao Khouay National Park, Vientiane metrium). An updated checklist with classification section Dendrobium in is al...

Dendrobium, a genus of orchid, was found to possess useful therapeutic activities like anticancer, hypoglycaemic, antimicrobial, immunomodulatory, hepatoprotective, antioxidant, and neuroprotective activities. The study was aimed to evaluate the anticancer property of the ethanolic extract of Dendrobium formosum on Dalton's lymphoma. In vitro cytotoxicity was determined by MTT assay, apoptosis ...

Dendrobium moniliforme (L.) Sw., an herb of the Orchidaceae family, has long been used in traditional medicine to strengthen bones, nourish the stomach, and promote the production of bodily fluid. Recently, polysaccharides isolated from Dendrobium have been used in functional foods and nutraceutical products. A traditional method to process Dendrobium is to soak fresh stems in an ethanol soluti...

Interactions between an isolate of dark septate endophytes (DSE) and roots of Dendrobium nobile Lindl. seedlings are reported in this paper. The isolate was obtained from orchid mycorrhizas on Dendrobium sp. in subtropical forest. The fungus formed typical orchid mycorrhiza in aseptic co-culture with D. nobile seedlings on modified Murashige-Skoog (MMS) medium. Anatomic observations of the infe...

Changes in stem diameter of orchid plants were investigated in a control growing climate. Previous studies have focused on stem diameter in relation to plant water on terrestrial plants in order to schedule the irrigation. The objective of this work was to evaluate the ability of the strain gauges to capture changes in the epiphytes plant stem. Experiments were carried out by using the sympodia...
