盐胁迫下与小麦生理响应相关的耐盐基因研究进展
Research Progress in Salt-tolerant Genes Related to Physiological Response of Wheat to Salt Stress
摘要
Abstract
Salt stress stands as one of the primary abiotic stresses severely endangering the growth and development of wheat.Salt tolerance in wheat represents a complex quantitative trait governed by multiple genes.These genes directly or indirectly engage in processes such as ion accumulation and exclusion,redox reactions,and the accumulation of specific osmoregulatory substances.Comprehending the current research landscape of salt-tolerant genes in wheat is conducive to the scientific and efficient breeding of salt-tolerant varieties.This article expounds on crop salt tolerance from four aspects:osmotic regulation,ion balance,ROS homeostasis,and hormone regulation mediated by salt-tolerant genes under salt stress.It summarizes the function of salt-tolerant genes in wheat's adaptation to salt stress,laying the groundwork for investigating the intricate mechanisms of wheat salt tolerance.Therefore,employing modern molecular biology techniques to explore salt-tolerant gene resources and introduce them into wheat is an effective approach to obtain high-yield,high-quality,and salt-tolerant wheat varieties.Research on genes associated with salt-stress tolerance plays a crucial role in elucidating the molecular mechanisms and pathways for dealing with salt stress.It offers significant guidance for cultivating outstanding germplasm with salt-stress tolerance and developing salt-tolerant cultivation techniques for wheat.关键词
