彩色马铃薯花色苷生物合成相关基因的研究进展

Anthocyanin Biosynthetic Genes in Colorful Potato

关键酶基因表达量决定了花色苷含量的高低,综述国内外对彩色马铃薯花色苷生物合成途径以及相关基因的研究现状,多个相关酶基因已经通过二倍体或四倍体马铃薯完成了cDNA的克隆,研究发现部分酶基因的启动子容易受到UVB辐射、低温等外界环境条件的诱导。对以后的研究工作提出了建议,希望能够为马铃薯花色苷的开发利用和生物合成相关基因的克隆、表达分析以及马铃薯分子育种提供参考依据。

Content of anthocyanin is depended upon the expression quantity of the critical genes. This paper reviewed the research achievements on the way of anthocyanin biosynthesis and the relative genes, cDNA of some genes are already cloned in diploid potato and Tuberosum potato. Promoters of some genes are liable to be induced by UVB and low temperature. This paper offers some advice on the research work in the future and hope it can offer some references for the research work upon the cDNA cloning, expression analysis and molecular breeding of colorful potato.
