  • RITF1, a newly identified plant transcription factor, links signalling through the peptide hormone RGF1 to the balance of reactive oxygen species and thereby enhances the stability of another transcription factor, PLETHORA2, a master regulator of root stem cells.

  • Cell-type-specific DNA methylation in plants has only been studied for reproductive tissues. Now a study reports cell-type-specific methylomes of the Arabidopsis root meristem, providing insights into the epigenetic diversity between somatic cell types.

  • A fundamental question in developmental biology is how cells communicate positional information to pattern the tissues of an organ. Here, the patterning of a plant's xylem tubes, which transport water and solutes from root to shoot, is studied. A new bidirectional signalling pathway is discovered, whereby a transcription factor moves from cell to cell in one direction, and microRNAs move in the other direction. The result is a differential distribution of target mRNA in the vascular cylinder, determining xylem cell types.

  • This Review considers mechanisms by which information is transmitted over short and long distances during plant development and how different modes of signalling integrate with gene regulatory networks to allow plants to respond to their environment.

  • A form of gene regulation that uses small RNA molecules to bind to longer RNAs was first described over a decade ago, but was thought to be of little significance in controlling cellular processes. No longer.

  • In higher animals and plants, the processes of growth and patterning are coordinated. In this study, the authors study patterning in Arabidopsis root and show that two key regulators of root organ patterning directly control the transcription of specific components of the cell-cycle machinery. This study provides a direct link between developmental regulators, components of the cell-cycle machinery and organ patterning.

  • Recent studies inArabidopsis thalianahave identified interconnected signalling networks that regulate plant vascular development. These findings have increased our understanding of vascular development from early cell specification during embryogenesis to the latest stages of differentiation of the phloem and xylem.
