Abstract excerpt
The floral homeotic gene APETALA1 (AP1) specifies floral meristem identity and sepal and petal identity in Arabidopsis. Consistent with its multiple roles during floral development, AP1 is initially expressed throughout the floral meristem, and later its expression becomes restricted to sepal and petal primordia. Using chromatin immunoprecipitation, we show that the floral homeotic PISTILLATA (PI) protein,...
