説明
Ion fluxes including Ca2+ and production of reactive oxygen species (ROS) are induced at the early step of defense signaling triggered by both biotic and abiotic (environmental) stresses. To reveal the molecular mechanisms and physiological roles of the plasma membrane Ca2+ influx, a family of putative voltage-gated Ca2+ permeable channels, the TPC1 family, were identified from various plant species. The rice gene, OsTPC1, rescued the Ca2+ uptake activity and growth rate of a yeast mutant defective in Ca2+ uptake. OsTPC1 overexpressing cells showed hypersensitivity to excess Ca2+ but higher growth rate under Ca2+ limitation, while growth of the transposon-insertional mutant (Ostpc1) cells was less sensitive to extracellular free Ca2+ concentration, suggesting that OsTPC1 has Ca2+ transport activity across the plasma membrane. Knockdown/knockout of the TPC1 family resulted in inhibition of [Ca2+]cyt rise in response to a pathogenic elicitor, as well as suppression of the elicitor-induced programmed cell death and defense-related gene expression. These results suggest that the TPC1 family is involved in elicitor-induced Ca2+ mobilization, and have crucial roles in stress-induced signal transduction pathways in plants.
