摘要:
磷酸蔗糖磷酸酶(sucrose phosphate phosphatase)是合成蔗糖的关键酶,为了研究其在芒果果实中蔗糖合成的作用机制,从芒果果肉中克隆得到1个与蔗糖合成相关的基因,将其命名为MinSPP,其cDNA全长序列为1 561 bp,开放阅读框为1 275 bp,编码424个氨基酸,蛋白质分子量为48.46 ku,等电点为5.34,对MinSPP基因编码的蛋白进行系统发育分析,发现其与克莱门柚具有较近的亲缘关系。采用qRT-PCR对该基因在后熟处理的贵妃芒果肉中的表达量进行分析,结果显示从青熟期到成熟期芒果果肉中该基因表达量逐渐上升,从成熟期到完熟期芒果果肉表达量逐渐降低,其中成熟期芒果果肉中表达量较高。本研究深入了解了芒果蔗糖合成的分子机制,进一步构建了pBI121-MinSPP过表达载体,为MinSPP的功能鉴定奠定了理论基础。
