Plant Cell Signaling: Compose Growth, Development, and Responses

Percy Andrus

Plant cell signaling is a complex network that regulates various aspects of plant growth, development, and responses to environmental stimuli. Phytohormones such as auxins, cytokinins, gibberellins, abscisic acid, and ethylene, along with small signaling molecules like Reactive Oxygen Species (ROS) and calcium ions (Ca²⁺), play significant roles in transmitting signals within and between plant cells. Signaling pathways, including the Mitogen-Activated Protein Kinase (MAPK) spout and phosphoinositide signaling pathway, transduce extracellular signals into intracellular responses. These signaling networks regulate diverse physiological processes, including development, defense responses against pathogens, and adaptation to abiotic stresses. Interpreting plant cell signaling holds promise for addressing global challenges in agriculture and food security amidst climate change and population growth.
