为了探究甘蓝型油菜BnaFUS3基因的非生物胁迫表达,以甘蓝型油菜‘湘油15’为供试材料,当油菜长成至6片真叶时期,对其进行6-BA、干旱、高温、低温、胁迫、水渍等逆境胁迫处理。结果表明BnaFUS3的两个拷贝在不同的逆境胁迫处理下其表达也不同。6-BA、干旱和高温处理下BnaA2.FUS3和BnaA6.FUS3的表达量均升高,说明能够诱导和促进BnaFUS3基因的表达,其中6-BA对BnaA6.FUS3的诱导大于BnaA2.FUS3,而在干旱条件下,24 h内BnaA2.FUS3的表达均大于BnaA6.FUS3,说明干旱对BnaA2.FUS3的诱导作用大于BnaA6.FUS3。盐胁迫、低温环境下抑制BnaFUS3的表达;ABA和水渍对BnaFUS3的表达影响波动较大,其中水渍条件下6~12 ...

In order to explore the abiotic stress expression of BnaFUS3 gene in Brassica napus,'Xiangyou15' was used as the experimental material. When the rape grows to the 6th leaf stage, it was subjected to stress treatment. The results showed that the expression of two copies of BnaFUS3 was different in different stress conditions. 6-BA, drought and high temperature could induce and promote the expression of BnaFUS3 gene. The induction of BnaA6.FUS3 by 6-BA was greater than BnaA2.FUS3, and the induction of BnaA2.FUS3 was greater than BnaA6.FUS3 in drought. The expression of BnaFUS3 was inhibited unde...
