摘要 CCCH型锌指蛋白是一类生物体中广泛存在的转录因子,与植物的抗逆性密切相关。水稻CCCH锌指蛋白家族包括67个成员,分为8个亚家族。本研究采用实时定量PCR技术分析水稻CCCH亚家族Ⅰ基因的组织表达模式以及盐、干旱、低温、高温等多种非生物胁迫和脱落酸(ABA)对CCCH基因表达水平的调节。结果表明,多数CCCH基因都不同程度地受到这些非生物胁迫及ABA的诱导或抑制,其中C3H10、C3H24、C3H33、C3H37和C3H67的表达量在不同胁迫处理后表现出不同程度的升高,C3H35、C3H50和C3H52在盐、干旱、ABA、低温和高温处理后表达水平呈下降趋势,表明这些CCCH锌指蛋白可能参与水稻的非生物胁迫响应。 CCCH - type zinc finger proteins, a kind of widely distributed transcription factors, are close- ly related to plant tolerance to stress. CCCH -type zinc finger protein family in rice contains 67 members, which are devided into 8 subfamilies. The tissue - specific expression patterns of CCCH - zinc finger protein subfamily I genes and the adjustment of ABA and abiotic stresses such as salt, drought, low and hight tem- perature to CCCH genes expression level were analyzed by real time PCR. The results showed that most of CCCH genes were induced or restrained by the abiotic stresses and ABA at varying degrees. The expression quantities of C3HIO, C3H24, C3H33, C3H37 and C3H67 genes were up - regulated, while those of C3H35, C3H50 and C3H52 genes were declining. It indicated that CCCH subfamily Ⅰ genes might be involved in re- sponse to abiotic stress.
