Peptide Signaling in Plant Development
Cell-to-cell communication is integral to the evolution of multicellularity. In plant development, peptide signals relay information coordinating cell proliferation and differentiation. These peptides are often encoded by gene families and bind to corresponding families of receptors. The precise spatiotemporal expression of signals and their cognate receptors underlies developmental patterning,...
متن کاملLigand-receptor pairs in plant peptide signaling.
Extensive studies on plant signaling molecules over the past decade indicate that plant cell-to-cell communication, as is the case with animal systems, makes use of small peptide signals and specific receptors. To date, four peptide-ligand-receptor pairs have been identified and shown to be involved in a variety of processes. Systemin and phytosulfokine (PSK), the first and second signaling pep...
متن کاملPhosphoinositide signaling in plant development.
The membranes of eukaryotic cells create hydrophobic barriers that control substance and information exchange between the inside and outside of cells and between cellular compartments. Besides their roles as membrane building blocks, some membrane lipids, such as phosphoinositides (PIs), also exert regulatory effects. Indeed, emerging evidence indicates that PIs play crucial roles in controllin...
متن کاملPlant Development: How Long Is a Root?
The plant hormone cytokinin controls root growth by balancing the division and differentiation of stem cells. But what controls accumulation of cytokinin? A new study has identified a regulatory loop between a transcription factor, PHABULOSA, and cytokinin biosynthesis that creates robust domains of cytokinin activity.
متن کاملReceptor kinase signaling in plant development.
The Arabidopsis genome sequence has revealed that plants contain a much larger complement of receptor kinase genes than other organisms. Early analysis of these genes revealed involvement in a diverse array of developmental and defense functions that included gametophyte development, pollen-pistil interactions, shoot apical meristem equilibrium, hormone perception, and cell morphogenesis. Amino...
