摘要:
为明确金银花WUSCHEL相关同源异型盒家族(WOX)基因的生物学功能及表达模式,基于金银花全基因组数据库,对LjWOX家族成员进行鉴定克隆、亚细胞定位与生物信息学分析,并通过实时荧光定量PCR(qRT-PCR)解析其表达特征。结果显示,金银花基因组中鉴定出12个LjWOX成员,分布于9条染色体,其氨基酸序列长度、分子量及等电点差异显著,且均定位于细胞核。系统发育分析将该家族分为远古支、中间支和WUS支;基因结构分析发现,LjWOX基因含1~3个内含子,编码蛋白均有保守基序Motif1与Motif2,部分成员具分支特异性基序,启动子区域富含光反应、激素及应激反应顺式作用元件。组织表达分析表明,LjWOX4、LjWOX8和LjWOX9在茎、叶及胚性愈伤组织中高表达。ABA和MeJA处理下,多数LjWOX基因上调表达:LjWOX2在ABA处理8 h达峰值,或为ABA信号早期响应关键基因;LjWOX5、LjWOX7、LjWOX8和LjWOX12在MeJA处理8 h显著上调,或参与茉莉酸信号传导调控。研究结果可为解析金银花生长发育与逆境适应分子机制提供理论依据。
