摘要

植物DnaJA蛋白作为分子伴侣对环境胁迫作出反应。本研究旨在探讨DnaJA基因在大豆中的作用及其调控机制。不同发育阶段大豆组织中的基因表达谱表明，GmDnaJAs在胁迫和植物激素反应的协调中发挥作用。GmDnaJA6被鉴定为耐盐碱胁迫的候选调节因子，并且GmDna JA6过表达系表现出增加的大豆耐盐碱性。DnaJ与Hsp70相互作用，GmHsp70提高了具有嵌合大豆毛状根的植物的耐盐碱性。

Genome-wide analysis of soybean DnaJA-family genes and functional characterization of GmDnaJA6 responses to saline and alkaline stress

Plant DnaJA proteins act as molecular chaperones in response to environmental stressors. The purpose of this study was to characterize the function and regulatory mechanisms of DnaJA genes in soybean. Gene expression profiles in various soybean tissues at various stages of development indicated that GmDnaJAs function in the coordination of stress and plant hormone responses. GmDnaJA6 was identified as a candidate regulator of saline and alkaline stress resistance and GmDnaJA6 overexpression lines showed increased soybean saline and alkaline tolerance. DnaJ interacted with Hsp70, and GmHsp70 increased the saline and alkaline tolerance of plants with chimeric soybean hairy roots.
