Plant Immunity Signaling

Plant immunity signaling is a sophisticated system that enables plants to detect and respond to pathogen attacks. This process relies on a series of signaling pathways that are activated upon pathogen recognition. The two primary types of immunity are pattern-triggered immunity (PTI) and effector-triggered immunity (ETI). PTI is initiated when plants recognize conserved microbial patterns, while ETI is activated by specific pathogen effectors. These signaling pathways involve various molecules, including reactive oxygen species, hormones like salicylic acid and jasmonic acid, and protein kinases. Understanding plant immunity signaling is essential for developing crops that can withstand diseases, which is critical for food security and agricultural sustainability.
