The team of academician Zhongkang reveals a new regulation mechanism during wheat vernalization

Recently, the team of Chinese Academy of Sciences academician and researcher of the Institute of Botany of the Chinese Academy of Sciences discovered that the new long-chain non-coding RNA VAS derived from the wheat VRN1 gene can recruit the transcription complex RF2b-RF2a to bind to the TaVRN1 promoter region and activate VRN1 Transcribe and promote flowering
.

Winter wheat flowering requires long-term induction of low temperature in the environment.
This process is called "vernalization"
.

Researchers found that before winter wheat vernalization, the TaVRN1 gene forms a loop loop structure at the positions of P2 and I4 under the action of some proteins, and the loop region contains a complete non-coding RNA VAS (VRN Alternative Splicing) sequence
.

The study by the health team and the kind of CAS plant researcher Zhang Wenhao team, Chinese Academy of Sciences researcher at the Institute of Genetics and Developmental Biology high pink clouds, Xiao Jun teamwork is completed, the Chinese Academy of Sciences plants graduated doctoral Xushu Juan as the first author of the paper, as a kind of health communication Author
