Abstract

Plant growth controls In plants the apical meristem at the tip of each shoot contains a population of stem cells ready to proliferate and direct plant growth when they receive the command. Comparative microarray experiments in Arabidopsis plants carrying inducible mutations of meristem regulators now show how plant hormones such as cytokinins can communicate with the meristem via a network of transcriptional activators and repressors. The homeobox protein WUSCHEL, known to control stem cell fate, has been found to act directly on a series of signalling proteins previously shown to participate in cytokinin signalling, thus providing a negative feedback loop for maintaining the size of the apical meristem.
