摘要:
钾是香蕉生长发育中需求量最大的营养元素,对果实产量、品质和贮藏性都有重要的影响。从香蕉基因组中鉴定出24个HAK/KUP/KT(MaKUP)基因,并对其理化性质、染色体定位、基因结构、保守功能域、进化关系、组织表达和低钾胁迫下的表达特征进行分析。结果表明,MaKUP编码的肽链平均有772个氨基酸,分子量为63.54~9382 ku,等电点为5.44~9.30,蛋白不稳定指数为32.69~44.29,脂肪族指数为105.34~116.90,总平均亲水性为 0.352~0.549,含有8~11个外显子,可分为4个亚族;表达分析发现15个MaKUP基因家族成员在香蕉不同发育时期的果实中高表达,6个MaKUP基因家族成员在低钾胁迫中上调表达,表明MaKUP在香蕉果实发育和钾吸收中具有重要的作用。
