大豆(Glycinemax L.)它被认为是一种重要的作物，在干旱胁迫下提高其产量和改变气候条件以应对全球粮食安全的挑战至关重要。干旱被认为是对大豆生产产生不利影响的主要非生物因素之一。为了应对这一挑战，我们需要开发一种综合研究方法，将计算模型、土壤工程学、生理学、微生物学、分子生物学、基因组学和植物育种结合起来，研究植物耐旱的潜在机制。基因组技术的进步与育种方法相结合，帮助科学家解开了导致作物耐旱性的基因。大豆育种计划的成功在很大程度上取决于与干旱有关的性状的遗传变异程度。整个大豆基因组序列的可获得性被认为是这一过程的一个主要里程碑，这将有助于设计未来提高大豆产量的战略。本文综述了干旱胁迫对大豆形态生化变化影响的研究进展，以及植物生长促生型根际细菌、分子标记辅助选择和不同组学方法在揭示大豆耐旱性机制中的应用。在这篇综述中，我们还重点介绍了生理学、功能基因组学和分子育种方面的常规知识，这些知识在整合基因工程和育种方法以提高大豆作物的抗旱性方面可能具有重要意义。
Soybean (Glycinemax L.) is considered an important crop, and enhancing its production under drought stress and changing climatic conditions to meet the challenges of global food security is crucial. Drought is considered one of the major abiotic factors that adversely affect soybean production. To address this challenge, we need to develop an integrative research approach that will bring together computational modelling, soil engineering, physiology, microbiology, molecular biology, genomics and plant breeding to study the underlying mechanisms of plant tolerance to drought stress. Advances in genomic technologies coupled with breeding approaches have helped scientists unravel the genes responsible for drought tolerance in crops. The success of a soybean breeding programme is largely dependent upon the extent of genetic variation in terms of drought tolerance-related traits. The availability of the whole soybean genome sequence is considered a major landmark in this process that will help design future strategies for improving soybean production. This review describes the recent advances in the study of the effect of drought stress on morpho-biochemical changes in soybean and the application of plant growth-promoting rhizobacteria, marker assisted selection, and different omics approaches to unravel the mechanism of drought tolerance. Here, in this review, we also highlight the customary knowledge on physiology, functional genomics and molecular breeding that may be significant in integrating genetic engineering and breeding approaches to improve drought tolerance in soybean crop.
