    摘要:

    水稻胁迫相关蛋白激酶(OsSAPKs,stress-activated protein kinase genes in rice)在调控水稻非生物胁迫信号传导中起着重要作用。本研究对OsSAPK9在水稻耐铝（Al）胁迫中的功能进行了初步研究。结果表明10 mmol/L Al处理后12h以上，OsSAPK9过表达转基因水稻植株根部Al的吸收量显著低于野生型植株；Al胁迫处理20d，OsSAPK9过表达转基因植株株高降低百分比显著低于野生型植株。进一步分析发现OsSAPK9过表达转基因水稻植株根部超氧化歧化酶（SOD，Superoxide Dismutase）和过氧化物酶（POD，Peroxidase）的活性高于野生型，而根上部的SOD、POD和过氧化氢酶（CAT, Catalase）的活性则低于野生型植株。上述结果为改良水稻的耐铝性以及进一步揭示OsSAPK9调控水稻耐铝胁迫反应的分子机制提供了信息。

    Abstract:

    Stress-activated protein kinase in rice (OsSAPKs) plays an important role in signal transduction. In this study, we analyzed the function of OsSAPK9 in response to Al stress in rice. The results indicated that absorptive capacity for aluminum in the roots of OsSAPK9 over-expressing transgenic rice was significantly lower than that of non-transgenic plants at 6?h, 2?d, 6?d and 10d after 10?mmol/L Al stress. Compared with the wild control, the reduction percent of plant height of OsSAPK9 over-expressing transgenic plants was significantly lower than that in non-transgenic plants 20?d after treatment using 10?mmol/L Al. Moreover, the activities of Superoxide Dismutase (SOD) and Peroxidase (POD) in the roots of OsSAPK9 over-expressing transgenic plants were higher than that in non-transgenic plants. While, the activities of SOD, POD and Catalase (CAT) in the parts above root of overexpression transgenic plants lower than that in non-transgenic plants. These results indicate that OsSAPK9 might be involved in the regulation of tolerant resistance response to Al stress in rice.
