【摘要】 将16个在拟南芥保卫细胞中进行特异性表达和8个非特异表达基因的转录起始密码子ATG上游-500bp的启动子序列在PLACE上进行分析,认为AAAAG基序和TAAAG基序控制某些基因在保卫细胞中进行特异性表达,但分析结果显示有的保卫细胞特异表达启动子的序列中却不含有这两个基序,说明还要其它类型的未知基序控制着保卫细胞中的特异表达,这一理论分析为进一步的实验研究提供了理论依据。更多还原

【Abstract】 The ATG-upstream 500bp sequences of 16 guard cell-specific and 8 non-guard cell-specific genes were analysised in the PLACE.These genes are all from Arabidopsis thaliana.The AAAAG motif and TAAAG motif contribute to the guard cell-specific in some genes.But the result revealed that some guard cell-specific genes do not contain these two motifs.This analysis supply some theory thereunder for the further experiment.更多还原
