[Identification and expression of uridine diphosphate glycosyltransferase(UGT) gene family from Dendrobium officinale].

Uridine diphosphate glycosyltransferase(UGT) is a highly conserved protein in plants, which usually functions in secondary metabolic pathways. This study used the Hidden Markov Model(HMM) to screen out members of UGT gene family in the whole genome of Dendrobium officinale, and 44 UGT genes were identified. Bioinformatics was used to analyze the structure, phylogeny, and promoter region components of D.

Morphological and stage-specific transcriptome analyses reveal distinct regulatory programs underlying yam (Dioscorea alata L.) bulbil growth.

In yam (Dioscorea spp) species, bulbils at leaf axils are the most striking species-specific axillary structure and exhibit important ecological niches. Genetic regulation underlying bulbil growth remains largely unclear so far. Here, we characterize yam (Dioscorea alata L.

Insights from the Cold Transcriptome and Metabolome of : Global Reprogramming of Metabolic and Gene Regulation Networks during Cold Acclimation.

Plant cold acclimation (CA) is a genetically complex phenomenon involving gene regulation and expression. Little is known about the cascading pattern of gene regulatroy network and the link between genes and metabolites during CA. (DOKM) is an important medicinal and ornamental plant and hypersensitive to low temperature.

Transciptome analysis reveals flavonoid biosynthesis regulation and simple sequence repeats in yam (Dioscorea alata L.) tubers.

Background: Yam (Dioscorea alata L.) is an important tuber crop and purple pigmented elite cultivar has recently become popular because of associated health benefits. Identifying candidate genes responsible for flavonoid biosynthesis pathway (FBP) will facilitate understanding the molecular mechanism of controlling pigment formation in yam tubers.

[Breeding of new Curcuma wenyujin variety "Wenyujin No. 1"].

In order to breed and spread a new cultivar of Curcuma wenyujin, the C. wenyujin germplasm resources were investigated in authentic regions. Better varieties were chosen by comparing the yield, economic characters and quality differences between different cultivars.

Anti-hepatitis B virus and cytotoxic diterpenoids from Isodon lophanthoides var. gerardianus.

Four new diterpenoides, isolophanthins A-D (1-4) together with seven known abietane diterpenoides (5-11), have been isolated from Isodon lophanthoides var. gerardianus. The new diterpenoides were elucidated by spectroscopic analysis.

[Analysis on adaptive area of Curcuma wenyujin based on GIS].

Objective: This stdudy was to determine the suitable area for Curcuma wenyujin in Wenzhou, and expand its growing region, based the growth characteristic of Curcuma wenyujin.

Methods: The 13 main factors including climate, soil and other environmental conditions were selected. The best genuine production area was regarded as the goal area in similar calculation.

Chemical constituents from aerial part of Curcuma wenyujin.

Objective: To investigate the chemical constituents from aerial part of Curcuma wenyujin.

Method: Compounds were isolated by repeated column chromatography on silica gel. Their structures were elucidated on the basis of spectral analysis and comparison with literature data.
