Water deficit is one of the major constraints for soybean production in Vietnam. The soybean breeding research efforts conducted at the Agriculture Genetics Institute (AGI) of Vietnam resulted in the development of promising soybean genotypes, suitable for the drought-stressed areas in Vietnam and other countries. Such a variety, namely, DT2008, was recommended by AGI and widely used throughout the country. The aim of this work was to assess the growth of shoots, roots, and nodules of DT2008 versus Williams 82 (W82) in response to drought and subsequent rehydration in symbiotic association as a means to provide genetic resources for genomic research. Better shoot, root, and nodule growth and development were observed in the cultivar DT2008 under sufficient, water deficit, and recovery conditions. Our results represent a good foundation for further comparison of DT2008 and W82 at molecular levels using high throughput omic technologies, which will provide huge amounts of data, enabling us to understand the genetic network involved in regulation of soybean responses to water deficit and increasing the chances of developing drought-tolerant cultivars.
水分亏缺是越南大豆生产的主要限制因素之一。越南农业遗传研究所（AGI）开展的大豆育种研究工作培育出了有前景的大豆基因型，适合越南及其他国家的干旱胁迫地区。AGI推荐了一个名为DT2008的品种，该品种在全国广泛使用。这项工作的目的是评估DT2008与威廉姆斯82（W82）在共生关系中对干旱及随后复水的响应下地上部、根系和根瘤的生长情况，以此为基因组研究提供遗传资源。在充足水分、水分亏缺和恢复条件下，DT2008品种的地上部、根系和根瘤生长发育情况更佳。我们的研究结果为利用高通量组学技术在分子水平上进一步比较DT2008和W82奠定了良好基础，这将提供大量数据，使我们能够了解参与调控大豆对水分亏缺响应的遗传网络，并增加培育耐旱品种的机会。
