| antimicrobial activity and biodiversity of endophytic fungi in dendrobium devonianum and dendrobium thyrsiflorum from vietman. | endophytic fungi are rich in orchids and have great impacts on their host plants. 53 endophytes (30 isolates from dendrobium devonianum and 23 endophytic fungi from d. thyrsiflorum) were isolated, respectively, from roots and stems of dendrobium species. all the fungi were identified by way of morphological and/or molecular biological methods. 30 endophytic fungi in d. devonianum were categorized into 11 taxa and 23 fungal endophytes in d. thyrsiflorum were grouped into 11 genera, respectively. ... | 2010 | 21181405 |
| molecular cloning and spatiotemporal expression of an apetala1/fruitfull-like mads-box gene from the orchid (cymbidium faberi). | in order to identify genes involved in floral transition and development of the orchid species, a full-length apetala1/fruitfull-like (ap1/ful-like) mads box cdna was cloned from cymbidium faberi (c. faberi) sepals and designated as c. faberi apetala1-like (cfap11], jq031272.1). the deduced amino acid sequence of cfap11 shared 84% homology with a member of the ap1/ful-like group of mads box genes (ay927238.1, dendrobium thyrsiflorum ful-like mads box protein 3 mrna). phylogenetic analysis shows ... | 2013 | 23697165 |
| identification of the geographic origin of dendrobium thyrsiflorum on chinese herbal medicine market using trinucleotide microsatellite markers. | the stems of dendrobium thyrsiflorum rchb.f. ex andré can be processed into an important class of traditional chinese medicine named "huangcao shihu," which has diverse curative effects, such as nourishing yin and clearing away unhealthy heat, benefiting the stomach, and promoting the production of body fluid. the identification of the geographical origin of d. thyrsiflorum is vital for preserving its natural resource and ensuring the quality of "huangcao shihu." in order to identify the origin ... | 2011 | 22130233 |
| [distribution and dynamic change of coumarins in leaf and root of dendrobium thyrsiflorum]. | to study the distribution and dynamic change of coumarins in the leaf and root of dendrobium thyrsiflorum at different developmental stages, and provide an experimental evidence for utilizing the medicinal plant. | 2009 | 19685736 |

| bi-bicyclic and bi-tricyclic compounds from dendrobium thyrsiflorum. | one bi-bicyclic and two bi-tricyclic derivatives of coumarin-benzofuran, phenanthrene-phenanthrene and phenanthrene-phenanthraquinone, along with seven known compounds, were isolated from stems of dendrobium thyrsiflorum rchb.f. (orchidaceae). on the basis of chemical, nmr (1h, 13c, hmqc, hmbc and noesy) and mass spectrometry data, their structures were elucidated as denthyrsin [3-(5',6'-dimethoxybenzofuran-2'-yl)-6,7-dimethoxy-2h-chromen-2-one; 1], denthyrsinol (4,5'-dimethoxy-[1,1']biphenanthr ... | 2005 | 15913675 |
| [location and relative quantity of coumarins in the stem of dendrobium thyrsiflorum]. | to determine the location and relative quantity of coumarins in the stem of dendrobium thyrsiflorum rchb. f. , and to provide a scientific basis for evaluating and utilizing the famous medicinal plant. | 2005 | 15952595 |
| [allele-specific diagnostic pcr authentication of dendrobium thyrsiflorum]. | the aim of this study was to establish a diagnostic pcr method for authentication of d. thyrsiflorum rchb. f. based on rdna its sequences of the 164 samples from 109 dendrobium species sequenced and quoted from genbank, the allele-specific diagnostic primers qh-jb1 and qh-jb2 for authentication were designed. using the primers, diagnostic pcr was performed with the total dna of d. thyrsiflorum rchb. f. and other d. species as templates to establish the positive pcr condition for d. thyrsiflorum ... | 2007 | 17520816 |
| simultaneous analysis of trans- and cis-isomers of 2-glucosyloxycinnamic acids and coumarin derivatives in dendrobium thyrsiflorum by high-performance liquid chromatography (hplc)-photodiode array detection (dad)-electrospray ionization (esi)-tandem mass spectrometry (ms). | a novel method has been developed for simultaneous analysis for three pairs of trans- and cis-isomers of 2-glucosyloxycinnamic acids, along with their biogenic metabolites (three coumarin derivatives including scopoletin, scoparone and ayapin) in a chinese medicinal herb dendrobium thyrsiflorum by using high-performance liquid chromatography (hplc)-photodiode array detection (dad)-electrospray ionization (esi)-tandem mass spectrometry (ms). the method was carried out by using a polaris c18 colum ... | 2006 | 17723413 |
| cloning and transcription analysis of an agamous- and seedstick ortholog in the orchid dendrobium thyrsiflorum (reichb. f.). | studies have shown that several plant species possess agamous (ag) and seedstick (stk) orthologs. these genes are part of the so-called c- and d mads-box gene lineages and play key roles in ovule development in arabidopsis thaliana. we have cloned an ag- and stk ortholog in the orchid dendrobium thyrsiflorum, named dthyrag1 and dthyrag2, respectively, and analyzed their expression patterns. quantification by real-time rt-pcr analysis shows that both are transcribed in the mature flowers and duri ... | 2006 | 16236468 |
