Arabidopsis B-BOX32 interacts with CONSTANS-LIKE3 to regulate flowering.

ABSTRACT: Plants have the ability to respond to seasonal environmental variations by monitoring day length to initiate flowering. The transition from vegetative to the reproductive stage is the critical developmental switch in flowering plants to ensure optimal fitness and/or yield. It has been previously reported that B-BOX32 (BBX32) has the potential to increase grain yield when ectopically expressed in soybean. In the present study, we performed a detailed molecular characterization of the Arabidopsis B-box domain gene BBX32 We showed that the circadian clock in Arabidopsis regulates BBX32 and expressed in the early morning. To understand the molecular mechanism of BBX32 regulation, we performed a large-scale yeast two-hybrid screen and identified CONSTANS-LIKE 3 (COL3)/BBX4 as one of its interac
