Effect of photoperiod on the regulation of wheat vernalization genes VRN1 and VRN2.

Plant molecular biology - 1 Mar 2006

Abstract excerpt

Wheat is usually classified as a long day (LD) plant because most varieties flower earlier when exposed to longer days. In addition to LD, winter wheats require a long exposure to low temperatures (vernalization) to become competent for flowering. Here we show that in some genotypes this vernalization requirement can be replaced by interrupting the LD treatment by 6 weeks of short day (SD), and that this...
