We are characterizing a suite of Pisum sativum mutants that alter inflorescence architecture to construct a model for the genetic regulation of inflorescence development in a plant with a compound raceme.
The compound raceme observed in Pisum may be accounted for by the suppression of second-order flower development by a second gene.
sativum has allowed us to identify genes that regulate key steps in compound raceme inflorescence development and to begin to explore their functions (Fig.
Thus comparative analysis may provide insight into an underlying genetic mechanism that distinguishes simple and compound racemes.
