就番茄耐旱和耐盐遗传改良的研究进展进行了综述。主要包括番茄耐旱和耐盐的野生资源及其遗传进化,基于基因组的QTL挖掘,QTL的遗传与累加效应,以及利用基因工程转入包括离子运输和区室化、渗透调节、活性氧清除、转录因子、胁迫蛋白等在内的外源基因,提高番茄的耐旱和耐盐性。就目前番茄耐旱和耐盐遗传改良过程中存在的问题与未来的应对策略,包括番茄耐旱和耐盐表型鉴定、全基因组关联分析、基因工程、基因的协同调控、小RNA、表观遗传学等,进行了探讨与展望。
The research progress on genetic improvement of drought tolerance and salt tolerance in tomato was reviewed. It mainly includes the genetic and genetic evolution of drought-tolerant and salt-tolerant tomato resources, genome-based QTL mining, the genetic and additive effects of QTL, and genetic engineering to include ion transport and compartmentalization, osmotic adjustment, reactive oxygen species removal, Transcription factors, stress proteins and other exogenous genes, improve tomato drought tolerance and salt tolerance. At present, the existing problems and future coping strategies of drought tolerance and salt tolerance genetic improvement in tomato include tomato drought tolerance and salt tolerance phenotype identification, genome-wide association analysis, genetic engineering, synergistic regulation of genes, small RNA, apparent Genetics, etc., were discussed and prospects.
