摘要:

渍水胁迫是威胁全球作物产量的主要非生物胁迫之一。渍水胁迫下,植物发生氧化胁迫、重金属毒害和能量缺乏,导致代谢紊乱,生长受到抑制。另一方面,植物在进化过程中形成了渍水耐性或适应机制,包括形态学和呼吸途径的变化,抗氧化保护以及内源激素调控。本综述介绍渍水胁迫的不利影响和植物耐渍性机制的最新研究进展,并阐述了植物种间或种内不同基因型之间耐渍性差异的遗传机理,还特别报道了植物中已鉴定到的与耐渍性相关的数量性状位点和关键基因。

Abstract:

Waterlogging is one of the major abiotic stresses threatening crop yields globally.  Under waterlogging stress, plants suffer from oxidative stress, heavy metal toxicity and energy deficiency, leading to metabolic disorders and growth inhibition.  On the other hand, plants have evolved waterlogging-tolerance or adaptive mechanisms, including morphological changes, alternation of respiratory pathways, antioxidant protection and endogenous hormonal regulation.  In this review, recent advances in studies on the effects of waterlogging stress and the mechanisms of waterlogging tolerance in plants are presented, and the genetic differences in waterlogging tolerance among plant species or genotypes within a species are illustrated.  We also summarize the identified QTLs and key genes associated with waterlogging tolerance.
