Root traits can be exploited to increase the physiological efficiency of crop water use under drought. Root length, root hairs, root branching, root diameter, and root proliferation rate are genetically defined traits that can help to improve the water productivity potential of crops. Recently, high-throughput phenotyping techniques/platforms have been used to screen the germplasm of major cool-season grain legumes for root traits and their impact on different physiological processes, including nutrient uptake and yield potential. Advances in omics approaches have led to the dissection of genomic, proteomic, and metabolomic structures of these traits. This knowledge facilitates breeders to improve the water productivity and nutrient uptake of cultivars under limited soil moisture conditions in major cool-season grain legumes that usually face terminal drought. This review discusses the advances in root traits and their potential for developing drought-tolerant cultivars in cool-season grain legumes. This article is protected by copyright.

冷季谷物豆类抗旱性的根组学

可以利用根性状来提高干旱条件下作物用水的生理效率。根长、根毛、根分枝、根直径和根增殖率是遗传定义的特征，可以帮助提高作物的水分生产力潜力。最近，高通量表型技术/平台已被用于筛选主要冷季豆科植物种质的根性状及其对不同生理过程的影响，包括养分吸收和产量潜力。组学方法的进步导致对这些特征的基因组、蛋白质组和代谢组结构的剖析。这些知识有助于育种者在通常面临终末干旱的主要冷季谷物豆科植物中，在有限的土壤水分条件下提高品种的水分生产力和养分吸收。这篇综述讨论了根性状的进展及其在冷季谷物豆类中开发耐旱品种的潜力。本文受版权保护。版权所有。
