The winter-annual habit (which typically involves a requirement for exposure to the cold of winter to flower in the spring) in Arabidopsis thaliana is mainly due to the repression of flowering by relatively high levels of FLC expression. Exposure to prolonged cold attenuates FLC expression through a process known as vernalization and thus permits flowering to occur in the spring. Here we show that the elevated FLC expression characteristic of nonvernalized winter annuals requires two genes… CONTINUE READING
