Solanaceous crops act as a source of food, nutrition and medicine for humans. Soil salinity is a damaging environmental stress, causing significant reductions in cultivated land area, crop productivity and quality, especially under climate change. Solanaceous crops are extremely vulnerable to salinity stress due to high water requirements during the reproductive stage and the succulent nature of fruits and tubers. Salinity stress impedes morphological and anatomical development, which ultimately affect the production and productivity of the economic part of these crops. The morpho-physiological parameters such as root-to-shoot ratio, leaf area, biomass production, photosynthesis, hormonal balance, leaf water content are disturbed under salinity stress in Solanaceous crops. Moreover, the synthesis and signalling of reactive oxygen species, reactive nitrogen species, accumulation of compatible solutes, and osmoprotectant are significant under salinity stress which might be responsible for providing tolerance in these crops. The regulation at the molecular level is mediated by different genes, transcription factors, and proteins, which are vital in the tolerance mechanism. The present review aims to redraw the attention of the researchers to explore the mechanistic understanding and potential mitigation strategies against salinity stress in Solanaceous crops, which is an often-neglected commodity.
茄科作物是人类食物、营养和药物的来源。土壤盐渍化是一种有害的环境胁迫，会导致耕地面积、作物生产力和品质大幅下降，尤其是在气候变化的情况下。茄科作物在生殖阶段对水分需求高，且果实和块茎肉质，极易受到盐胁迫的影响。盐胁迫会阻碍形态和解剖学发育，最终影响这些作物经济部位的产量和生产力。在盐胁迫下，茄科作物的形态生理参数，如根冠比、叶面积、生物量生产、光合作用、激素平衡、叶片含水量等都会受到干扰。此外，活性氧、活性氮的合成与信号传导、相容性溶质的积累以及渗透保护剂在盐胁迫下也很重要，这可能是这些作物具有耐受性的原因。分子水平的调控由不同的基因、转录因子和蛋白质介导，它们在耐受机制中至关重要。本综述旨在重新引起研究人员的关注，以探索对茄科作物盐胁迫的机理理解和潜在缓解策略，茄科作物是一种常被忽视的作物。
