High impact information on Dendrobium

• We report here the isolation and identification of an orchid homeobox gene, DOH1, from Dendrobium Madame Thong-In [1].
• We have cloned an AG- and STK ortholog in the orchid Dendrobium thyrsiflorum, named DthyrAG1 and DthyrAG2, respectively, and analyzed their expression patterns [2].
• Cloning and transcription analysis of an AGAMOUS- and SEEDSTICK ortholog in the orchid Dendrobium thyrsiflorum (Reichb. f.) [2].
• Functional characterisation of a cytokinin oxidase gene DSCKX1 in Dendrobium orchid [3].
• cDNA fragments representing 21 R2R3-MYB genes were isolated by RT-PCR from the Dendrobium orchid hybrid Woo Leng [4].

Associations of Dendrobium with chemical compounds

• Simultaneous determination of phenols (bibenzyl, phenanthrene, and fluorenone) in Dendrobium species by high-performance liquid chromatography with diode array detection [5].
• Bioassay-guided fractionation of the EtOAc-soluble extract of Dendrobium moniliforme afforded a new phenanthraquinone-type metabolite, 7-hydroxy-5,6-dimethoxy-1,4-phenanthrenequinone ( 1), along with the previously reported 5-hydroxy-3,7-dimethoxy-1,4-phenanthrenequinone ( 2) [6].
• Two phenanthrenes were isolated from the aerial part of Dendrobium nobile Lindl. and their structures were identified to be 4,7-dihydroxy-2-methoxy-9,10-dihydrophenanthrene (1) and denbinobin (2), among which the former has been first isolated from this plant [7].
• A new VHR dual-specificity protein tyrosine phosphatase inhibitor from Dendrobium moniliforme [6].
• Moscatilin from Dendrobium nobile, a naturally occurring bibenzyl compound with potential antimutagenic activity [8].

Gene context of Dendrobium

• Cloning and expression of a novel cDNA encoding a mannose-binding lectin from Dendrobium officinale [9].

Analytical, diagnostic and therapeutic context of Dendrobium

• We have cloned a novel putative cytokinin oxidase, DSCKX1 (Dendrobium Sonia cytokinin oxidase), by mRNA differential display from shoot apices of Dendrobium Sonia cultured in the presence of BA [3].
