Résumé:

Calcium is a universal messenger involved in the modulation of diverse developmental and adaptive processes in response to various physiological stimuli. Ca^2 + signals are represented by stimulus-specific Ca^2 + signatures that are sensed and translated into proper cellular responses by diverse Ca^2 + binding proteins and their downstream targets. Calmodulin (CaM) and calmodulin-like (CML) proteins are primary Ca^2 + sensors that control diverse cellular functions by regulating the activity of various target proteins. Recent advances in our understanding of Ca^2 +/CaM-mediated signalling in plants have emerged from investigations into plant defence responses against various pathogens. Here, we focus on significant progress made in the identification of CaM/CML-regulated components involved in the generation of Ca^2 + signals and Ca^2 +-dependent regulation of gene expression during plant immune responses. This article is part of a Special Issue entitled: 12th European Symposium on Calcium.
