Clarifying the mechanism that controls flowering in Napa cabbage
June 28, 2019
A joint research group with members from Kobe University, Niigata University, RIKEN CSRS, NARO and Australia’s CSIRO has succeeded in a comprehensively identifying long noncoding RNA (lncRNA) in Napa cabbage (B. rapa L. var. pekinensis). nlcRNA is one type of RNA responsible for vernalization, which is a period of prolonged cold before flowering. Of the three types of Napa cabbage lncRNA identified by researchers, none acted to control vernalization as they do in A. thaliana, a model plant in the same Brassicaceae family. These findings suggest that a unique molecular mechanism may exist for the vernalization mechanism of Napa cabbage.
The results are expected to contribute to the future breeding of varieties of Brassicaceae (cruciferous) vegetables.
