Global temperature rise is emerging as an alarming threat to agriculture and especially for vegetables, as they are more sensitive to high temperature because of their succulent nature. Vegetables include different edible plant parts such as leaves, stems, stalks, roots, tubers, bulbs, flowers, fruits, and seeds. An increase in temperature impairs the growth and development of vegetable plants and eventually reduces their yield. Heat tolerance is a complex quantitative trait that involves a series of physiological, biochemical, and molecular pathways. This complexity is further exacerbated by the presence of a large magnitude of genotype × environment and epistatic interactions, so breeders have to face challenges during development and selection of heat tolerant genotypes. Understanding the response of plants and resistance mechanisms involved in heat tolerance would help the breeders in formulating strategies to improve vegetable productivity under heat stress. In this review, firstly the impact of heat stress on the morphological, physiological, and molecular processes of different vegetables have been described, then discussed adaptation mechanisms employed by plants to combat heat stress. Finally, conventional and potential genomic strategies i.e. marker-assisted breeding, quantitative trait loci mapping, genome wide association, genomic selection, genetic engineering, and genome editing that are being used by the breeders to create heat resistance are presented. For vegetables, genome editing, and transgenic approaches need to be combined with conventional and marker-assisted breeding activities to develop heat tolerant varieties as these efforts will lead to tangible practical outcomes that will improve the vegetable productivity.

当前基因组时代蔬菜的耐热性：概述

全球气温上升正在成为对农业尤其是蔬菜的惊人威胁，因为它们的多汁性质对高温更敏感。蔬菜包括不同的可食用植物部分，例如叶、茎、茎、根、块茎、鳞茎、花、果实和种子。温度升高会损害蔬菜植物的生长发育并最终降低其产量。耐热性是一种复杂的数量性状，涉及一系列生理、生化和分子途径。大量基因型×环境和上位相互作用的存在进一步加剧了这种复杂性，因此育种者在耐热基因型的开发和选择过程中必须面临挑战。了解植物的反应和耐热性所涉及的抗性机制将有助于育种者制定提高热胁迫下蔬菜生产力的策略。在这篇综述中，首先描述了热应激对不同蔬菜的形态、生理和分子过程的影响，然后讨论了植物对抗热应激的适应机制。最后，介绍了传统和潜在的基因组策略，即标记辅助育种、数量性状基因座作图、全基因组关联、基因组选择、基因工程和基因组编辑，育种者正在使用这些策略来产生耐热性。对于蔬菜，基因组编辑，
