Abstract
Plants have developed well-orchestrated strategies to defend against pathogen attack. Several subcellular compartments and interactions between organelles play an important role in the activation of a successful immune response against invading pathogens. Chloroplasts are a major production site of pro-defense molecules. In addition, they communicate and coordinate with other organelles during defense via stromules, dynamic tubular extensions from chloroplasts. Recently stromules have been proposed to transport pro-defense signals into the nucleus during immunity. Interestingly, stromules extend along MTs and connect to AF anchor points surrounding nuclei, facilitating pulling of chloroplasts to nuclei during innate immunity. In this seminar, I will introduce chloroplast-nuclear communication via stromule and the regulation the dynamics of stromule by plant cytoskeleton during plant immune responses.
