Paphiopedilum wardii Sumerh. is an endangered tropical terrestrial orchid threatened with extinction due to over-collection and loss of suitable habitats. Asymbiotic germination provides a useful way re-establish plants in the wild (conservation) for commercial propagation. The seeds collected from 180 days after pollination (DAP) were optimum culture vitro, seed reached 65.33% on half-strength MS (1/2 macro- micro-nutrients) medium containing 0.5 mg l−1 α-naphthaleneacetic acid (NAA), 10%...

The successful ex vitro establishment of Dendrobium plantlets raised in determines the quality end product (cut flowers or potted plants) commercial production for economic gain. When are transplanted from culture room to greenhouse conditions, they may desiccate wilt rapidly and can die as a result changes environment, unless substantial precautions taken adapt new environment. acclimatization vitro-grown an environment by gradually weaning them towards ambient relative humidity light...

Abstract Background The orchids of the subtribe Coelogyninae are among most morphologically diverse and economically important groups within subfamily Epidendroideae. Previous molecular studies have revealed that is an unambiguously monophyletic group. However, intergeneric infrageneric relationships largely unresolved. There has been long controversy over classification genera subtribe. Results complete chloroplast (cp.) genomes 15 species in were newly sequenced assembled. Together with...

Dendrobium officinale is one of the most important Chinese medicinal herbs. Polysaccharides are main active ingredients D. officinale. To identify genes that maybe related to polysaccharides synthesis, two cDNA libraries were prepared from juvenile and adult officinale, named Dendrobium-1 Dendrobium-2, respectively. Illumina sequencing for generated 102 million high quality reads assembled into 93,881 unigenes with an average sequence length 790 base pairs. The Dendrobium-2 86 114,098 695...

Abstract Santalum album L. (Indian sandalwood) is an economically important plant species because of its ability to produce highly valued perfume oils. Little known about the mechanisms by which S. adapts low temperatures. In this study, we obtained 100,445,724 raw reads paired-end sequencing from leaves. Physiological and transcriptomic changes in sandalwood seedlings exposed 4 °C for 0–48 h were characterized. Cold stress induced accumulation malondialdehyde, proline soluble carbohydrates,...

It is well known that aromatic essential oils extracted from the heartwood of Santalum album L. have wide economic value. However, little about role terpenoids in response to various adverse environmental stresses as other plants do form signals during plant-environment interactions.In this study, trace amounts volatiles consisting α-santalene, epi-β-santalene, β-santalene, α-santalol, β-santalol, (E)-α-bergamotene, (E)-β-farnesene and β-bisabolene were found leaves mature S. trees. We...

Dendrobium officinale is a precious traditional Chinese medicinal plant because of its abundant polysaccharides found in stems. We determined the composition water-soluble and starch content D. The extracted polysaccharide was as high 35% (w/w). Analysis monosaccharides showed that were dominated by mannose, to lesser extent glucose, small amount galactose, molar ratio 223:48:1. Although also found, less than 10%. This result indicated major stems non-starch polysaccharides, which might be...

Abstract An efficient regeneration system via shoot organogenesis and somatic embryogenesis from in vitro leaf root explants was established for Scaevola sericea the first time. The highest axillary proliferation coefficient (4.8) obtained on Murashige Skoog (MS) medium supplemented with 1.0 mg/L 6-benzyladenine (BA) 0.1 α -naphthaleneacetic acid (NAA) every 45 days. Young leaves roots, which were used as explants, cultured onto different plant growth regulators. Our results showed that only...

Delayed radiation-induced brain injury (RIBI) characterized by progressive cognitive decline significantly impacts patient outcomes after radiotherapy. The activation of NLRP3 inflammasome within microglia radiation is involved in the progression RIBI mediating inflammatory responses. We have previously shown that sulfonylurea receptor 1-transient potential M4 (SUR1-TRPM4) mediates microglial NLRP3-related inflammation following global ischemia. However, role SUR1-TRPM4 remains unclear....
