Spatiotemporal signalling in plant development.
Plants, being sessile organisms, need to respond to changing environments, and as a result they have evolved unique signalling mechanisms that allow rapid communication between different parts of the plant. The signalling mechanisms that direct plant development include long-range effectors, such as phytohormones, and molecules with a local intra-organ range, such as peptides, transcription factors and some small RNAs. In this Review, we highlight recent advances in understanding plant signalling mechanisms and discuss how different classes of signalling networks can integrate with gene regulatory networks and contribute to plant development. In some cases, we also address the evolutionary context of mechanisms and discuss possible links between the lifestyle of plants and selection for different signalling mechanisms.
