| 英文摘要 | oligochitosan has been proved to trigger plant cell death. to gain some insights into the mechanisms of oligochitosan-induced cell death, the nature of oligochitosan-induced cell death and the role of calcium (ca2+), nitric oxide (no) and hydrogen peroxide (h2o2) were studied in tobacco suspension cells. oligochitosan-induced cell death occurred in cytoplasmic shrinkage, phosphatidylserine externalization, chromatin condensation, tunel-positive nuclei. cytochrome c release and induction of programmed cell death (pcd)-related gene hsr203j, suggesting the activation of pcd pathway. pretreatment cells with cyclosporin a, resulted in reducing oligochitosan-induced cytochrome c release and cell death, indicating oligochitosan-induced pcd was mediated by cytochrome c. in the early stage, cells undergoing pcd showed an immediate burst in free cytosolic ca2+ ([ca2+](cyt)) elevation, no and h2o2 production. further study showed that these three signals were involved in oligochitosan-induced pcd, while ca2+ and no played a negative role in this process by modulating cytochrome c release.
