摘要: 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。

Abstract: The genetic improvement of tomato tolerance to drought and salt stress was reviewed in this paper. The contents mainly included the potential wild tomato species for drought and salt tolerance and the evolution,QTL exploration,the genetic and stacking effects of the identified QTLs,and the genetic engineering with exogenous genes,including ion transport and compartmentalization,osmotic regulation,antioxidant protection,transcription factor,stress related proteins,for tomato genetic improvement with drought and/or salt tolerance. Meanwhile,the present problems and future strategies,mainly including phenotype determination of drought and salt tolerance in tomato,genome wide association study(GWAS),genetic engineering,cross-talking,small RNA and epigenetics,were also discussed.

Key words: tomato, abiotic stress, salt tolerance, drought tolerance, genetic improvement
