Abstract

Flower Power The transcription factor APETALA1 (AP1) controls the transition from vegetative growth to flower production in the plant Arabidopsis . A handful of factors that control AP1 have been identified, as well as some targets that AP1 controls. Kaufmann et al. (p. 85 ) now apply genome-wide microarray analysis to identify over a thousand genes whose transcription is regulated by AP1. By proximity to AP1 binding sites, over two thousand genes are implicated as putative AP1 targets. Analysis of this network of interactions indicates that AP1 functions first to repress vegetative identity, then to help establish floral primordia, and finally to shape the differentiation of floral parts.
