DRN facilitates WUS transcriptional regulatory activity by chromatin remodeling to regulate shoot stem cell homeostasis in Arabidopsis.

Shoot stem cells, harbored in the shoot apical meristem (SAM), play key roles during post-embryonic development of Arabidopsis and function as the origin of plant aerial tissues. Multiple transcription factors are involved in the sophisticated transcriptional regulation of stem cell homeostasis, with the WUSCHEL (WUS)/CLAVATA3 (CLV3) negative feedback loop playing a central role. WUS acts as a master regulator in maintaining stem cells through its transcriptional regulatory activity including repressive and activating abilities.

Complete mitochondrial genome of Grum-Grshimailo, 1891 (Lepidoptera: Pieridae) from montane region in northwestern China.

Grum-Grshimailo, 1891, is a typical montane butterfly species which occurs on the Qinghai-Tibet Plateau (QTP) and adjacent regions in China. In this study, the complete mitochondrial genome of this species was assembled from data generated by next-generation sequencing. The mitogenome was 15,151 bp in length and comprised 13 protein-coding genes (PCGs), 2 ribosomal RNA genes, 22 transfer RNA genes and a control region.

Validation of reference genes for gene expression analysis in fruit development of Vaccinium bracteatum Thunb. using quantitative real-time PCR.

Vaccinium bracteatum Thunb. (VBT) is widely distributed in the mountainous areas in eastern and southern China. VBT leaves have great medical value and can be used to stain rice to produce "Wumifan".

sp. nov. and sp. nov., isolated from hypersaline environments.

Two novel extremely halophilic archaeal strains, designated H27 and FL145, were isolated from a salt mine and a kelp salt sample, respectively. Cells of both strains were Gram-stain-negative, motile and pleomorphic. The 16S rRNA and ' gene sequence similarities between strains H27 and FL145 were 96.
