Annexin-mediated signalling in stress and defence

Annexins are soluble, multifunctional proteins which have proposed roles in coordinating reactive oxygen species and Ca2+ signalling networks (1). Annexins are capable of calcium-dependent membrane attachment or insertion and can form calcium-permeable channels in plants and animals (1). As such, annexins should have an impact on calcium-mediated signalling in plants but this remains unexplored. Arabidopsis mutants transformed to express cytosolic calcium indicators will permit the role of annexins in generating calcium signals in response to environmental/defence stimuli to be addressed.
