Receptor-like kinases shape the plant
To generate the various tissues and organs that build up the adult body, plants and animals require organized formative cell divisions and correct cell specification. In plants, these processes are controlled mainly by phytohormones and transcriptional networks. Recently, ligand-receptor-like kinase signalling pathways have been revealed as additional potentially crucial regulators of cell specification in plants. We review here the importance of such signalling cascades for plant growth and development, and we discuss, where possible, similarities to well-investigated cascades in animals.
