摘要:
蔗糖合酶(Sucrose synthase,简称SUS)是蔗糖代谢的关键酶之一,在植物糖积累及非生物胁迫响应中具有重要作用。泡桐(Paulownia fortunei)具有速生、材质优良、易繁殖、抗干旱、耐盐碱等特点。为研究SUS基因在泡桐生长发育及盐胁迫中发挥的作用,本研究以白花泡桐为试验材料,运用生物信息学方法,对泡桐SUS基因家族进行鉴定,对其理化性质、亚细胞定位、染色体定位、基因结构、保守基序、家族基因共线性、系统进化进行分析,利用转录组数据分析其盐胁迫前后表达模式。结果显示,共鉴定出12个SUS基因,长度在519~1 061 aa,相对分子质量在58.59~11880 ku,蛋白序列、结构高度保守,所有基因均定位在叶绿体上,分布在10条染色体上;系统进化分析得出,12个SUS基因分为3类,泡桐SUS基因与拟南芥SUS基因同源性较高;顺式元件分析显示,12个SUS基因启动子中含有与逆境、植物生长发育、植物代谢相关的响应元件;表达模式分析结果表明,有成员在盐胁迫处理下的泡桐表达水平有一定的变化,其中Pfo01g001790在盐胁迫前后表达差异最为明显。
