Abstract
During the transition from vegetative growth to flowering, shoot meristem cells become committed to forming floral primordia and eventually flowers. A series of mutants that influence the timing of this switch were identified in Arabidopsis, and we isolated the CONSTANS (CO) gene which is affected in a late-flowering mutant. I propose to perform a sector analysis to determine where expression of CO is required to promote the transition from vegetative growth to flowering, and whether its expression correlates with the time at which the shoot meristem becomes committed to forming flowers. We also identified a second mutation, esd4, that suppresses the effect of Co mutations, and I propose to isolate the ESD4 gene to determine how it interacts with CO.
