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.
