摘　　要：马铃薯(Solanum tuberosum)块茎中淀粉含量及其代谢对淀粉加工影响极大。解析参与马铃薯淀粉代谢过程关键酶的功能及其表达调控,有助于通过基因工程对马铃薯块茎淀粉含量及品质进行改良。本文详细综述了马铃薯淀粉代谢过程中关键酶编码基因的研究进展及其在马铃薯淀粉改良方面的研究成果;同时,提出了通过对马铃薯淀粉代谢网络中关键基因顺式调控元件鉴定并进行分子操作,从而提高马铃薯块茎淀粉含量及品质的可能性,为创制兼备粮食和能源用途的高淀粉含量马铃薯品种提供一种潜在手段。Starch content and its metabolism in potato(Solanum tuberosum)tubers have great impact on starch processing.Deciphering the functions and expression regulation of key genes involving in starch metabolism will promote to improve potato starch content and quality through genetic engineering.In this review,recent advances on genes encoding key enzymes in potato starch metabolism and their application in starch improvement were summarised.In particular,the identification of cis-regulatory elements for the starchrelated genes and their potential advantages in improving starch content and quality were discussed.The application of cis-regulatory elements in potato breeding may provide a new feasible strategy to create cultivars required for both food and energy alcohol industry.
