摘要:
植物NAC1转录因子在调控植物的抗生物胁迫反应中起着重要的作用。为探究生物逆境相关NAC1转录因子的功能，通过生物信息学的方法对8个生物逆境胁迫相关NAC1蛋白氨基酸序列一致性、氨基酸组成、理化性质、亲/疏水性、保守结构域、磷酸化位点、亚细胞定位、二级结构及三级结构等进行了预测和分析。结果表明，8个生物逆境胁迫相关NAC1蛋白N-端保守性较强，包括5个保守的亚结构域，共同组成NAC1结构域。C-端含有多个保守的氨基酸，具有转录激活功能。同时蛋白中含有多个丝氨酸(S)、苏氨酸(T)和酪氨酸(Y)磷酸化位点。8个NAC1蛋白都为亲水性蛋白，大多定位于细胞核，个别定位于细胞质或叶绿体。二级结构则以α-螺旋和β-折叠为主。8个NAC1蛋白三维结构上的相似性暗示了功能上存在相似。本研究结果为进一步挖掘生物逆境相关NAC1转录因子的功能和改良植物抗生物逆境特性提供理论依据。
