摘要:
首先研究小麦16.9 ku小分子热激蛋白(small heat shock protein,简称sHSP)基因(sHSP16.9)3′-UTR中微型反向重复转座元件(miniature inverted-repeat transposable elements,简称MITE)插入对基因表达调控的影响,结果显示:热胁迫下,具有MITE插入的基因型中sHSP16.9基因转录水平较无MITE插入的基因型明显提高,而MITE是一类特殊的DNA介导的转座子,推测其参与基因表达调控。随后研究MITE参与基因表达调控的机制,构建2种不同的植物表达载体pCAMBIA Super-1300+sHSP16.9、pCAMBIA Super-1300+sHSP16.9+MITE转化拟南芥,结果显示:sHSP16.9+MITE超表达的转基因拟南芥中,sHSP16.9基因表达量较sHSP16.9超表达的转基因拟南芥明显提高;高温胁迫下,sHSP16.9+MITE超表达的转基因拟南芥中种子发芽率、幼苗存活率、游离脯氨酸含量均较sHSP16.9超表达的转基因拟南芥明显提高,而丙二醛含量升高的幅度明显低于sHSP16.9超表达的转基因拟南芥。由结果可知,sHSP16.9+MITE超表达的转基因拟南芥耐热性水平较sHSP16.9超表达的转基因拟南芥高,推测sHSP16.9基因3′-UTR中MITE插入增强该基因的表达。
