Molecular characterization of pathogen-induced SlCBL1-2, a calcium sensor, reveals the structural basis of calcium sensing in tomato

Calcium (Ca2+) is a universal second messenger that orchestrates plant growth, development, and stress responses. Plant calcineurin B-like (CBL) proteins sense and relay Ca2+; signals in response to pathogens to activate downstream defense signalling pathways. Early blight disease, caused by the necrotrophic fungal pathogen Alternaria solani, affects tomato crops and severely limits their…
