Food is indispensable for fulfilling the nutritional requirements of living beings. The principal source of food, nutrition and feed are horticultural commodities. Grains, pulses, fruits, vegetables, flowers, ornamental plants and medicinal plants are just a few of the important horticulture crops that are widely grown as cash crops by farmers and to meet these needs. However, eventually, horticulture crops are facing major challenges to enhance the productivity of field crops due to changes in environmental conditions. Crops are affected by many environmental stresses including both biotic as well as abiotic. Environmental stresses affect the overall growth, development, physiology and metabolism of plants which leads to the loss of crop quality produce and yield. Old approaches to decipher the mechanism of stress management and overall improvement in plants are involved with tedious experiments, long breeding programs and different cultivation environments. With the advancement in the field of bioinformatics and next-generation sequencing technologies, it has become possible to study the molecular mechanisms of plants coping with stresses. It is the need of the hour to investigate the mechanism of stress tolerance in economically important horticultural crops. This area has sought the attention of horticulturists as many regions are under the spell of environmental alterations and climate change. Thus, this review takes up the genetic and epigenetic aspects of stress management in high-value horticultural fruit and vegetable plants.

园艺作物应对压力:遗传和表观遗传改变

食物对于满足生物的营养需求是必不可少的。食物、营养和饲料的主要来源是园艺商品。谷物、豆类、水果、蔬菜、花卉、观赏植物和药用植物只是农民作为经济作物广泛种植并满足这些需求的重要园艺作物中的一小部分。然而,最终,由于环境条件的变化,园艺作物面临着提高大田作物生产力的重大挑战。作物受到许多环境胁迫的影响,包括生物和非生物胁迫。环境胁迫会影响植物的整体生长、发育、生理和代谢,从而导致作物质量和产量的损失。破译压力管理和植物整体改良机制的旧方法涉及繁琐的实验、漫长的育种计划和不同的栽培环境。随着生物信息学和新一代测序技术的进步,研究植物应对逆境的分子机制成为可能。研究具有重要经济意义的园艺作物的胁迫耐受机制是当务之急。由于许多地区受到环境变化和气候变化的影响,该地区已经引起了园艺家的注意。因此,本综述探讨了高价值园艺水果和蔬菜植物压力管理的遗传和表观遗传方面。漫长的育种计划和不同的栽培环境。随着生物信息学和新一代测序技术的进步,研究植物应对逆境的分子机制成为可能。研究具有重要经济意义的园艺作物的胁迫耐受机制是当务之急。由于许多地区受到环境变化和气候变化的影响,该地区已经引起了园艺家的注意。因此,本综述探讨了高价值园艺水果和蔬菜植物压力管理的遗传和表观遗传方面。漫长的育种计划和不同的栽培环境。随着生物信息学和新一代测序技术的进步,研究植物应对逆境的分子机制成为可能。研究具有重要经济意义的园艺作物的胁迫耐受机制是当务之急。由于许多地区受到环境变化和气候变化的影响,该地区已经引起了园艺家的注意。因此,本综述探讨了高价值园艺水果和蔬菜植物压力管理的遗传和表观遗传方面。研究植物应对胁迫的分子机制已成为可能。研究具有重要经济意义的园艺作物的胁迫耐受机制是当务之急。由于许多地区受到环境变化和气候变化的影响,该地区已经引起了园艺家的注意。因此,本综述探讨了高价值园艺水果和蔬菜植物压力管理的遗传和表观遗传方面。研究植物应对胁迫的分子机制已成为可能。研究具有重要经济意义的园艺作物的胁迫耐受机制是当务之急。由于许多地区受到环境变化和气候变化的影响,该地区已经引起了园艺家的注意。因此,本综述探讨了高价值园艺水果和蔬菜植物压力管理的遗传和表观遗传方面。
