Identification of the VERNALIZATION 4 gene reveals the origin of spring growth habit in ancient wheats from South Asia.

Abstract

Wheat varieties with a winter growth habit require long exposures to low temperatures (vernalization) to accelerate flowering. Natural variation in four vernalization genes regulating this requirement has favored wheat adaptation to different environments. The first three genes (VRN1-VRN3) have been cloned and characterized before. Here we show that the… (More)
