摘要:
糖基转移酶基因通过催化植物体内化合物发生糖基化反应，改变这些化合物的生物活性和功能，进而影响植物的生长发育。为探究毛果杨GT43家族基因在木聚糖主链合成中的作用，本研究以毛果杨为材料，对杨树GT43基因家族成员进行生物信息学分析和基因表达研究。结果表明，毛果杨基因组中共鉴定到7个GT43基因成员，依次命名为GT43A~GT43G。其中，除GT43F外，其余6个家族成员均含有较完整的基因结构，1个共同的保守基序(motif2)，1个保守的三级结构域，且N端存在1个或2个跨膜结构。系统发育分析发现，7个基因分别与拟南芥IRX9、IRX9-L、IRX14、IRX14-L是同源基因，并且亲缘关系较近。顺式作用元件分析表明，GT43基因家族成员主要含光响应元件、逆境胁迫相关元件以及激素响应相关元件。此外，除GT43F、GT43G外，其余5个基因主要在茎木质部中表达水平较高，表明GT43基因在杨树木质部形成过程中起着重要作用。综上，本研究分析了毛果杨GT43基因家族特征，其结果可为后续GT43基因家族参与木聚糖主链的合成研究提供理论基础。
