Plant Endosymbiotic Organellar Calcium Signaling under Biotic and Abiotic Stresses

Author(s):

Hironari Nomura and Takashi Shiina

Mitochondria and chloroplasts in eukaryotic cells are endosymbiotic organelles derived from an α-proteobacterium and a cyanobacterium, respectively. The former are responsible for oxidative respiration, while the latter are the sites of photosynthesis within photosynthetic eukaryotic cells. The catabolic and anabolic processes in these organelles are regulated in response to a fluctuating environment. Ca2+ plays important roles in signal transduction pathways mediating a wide variety of physiological responses in eukaryotic cells. An increase in cytosolic Ca2+ concent... view more»
