Salinity is an important abiotic stress that has an impact on crop yields and quality. Ubiquitin-mediated protein degradation enables plants to effectively withstand environmental stresses. The E3 ligases have been identified as a crucial component of the ubiquitination pathway, which regulates plant responses to abiotic stresses. The RING finger E3 ligase family of proteins has a critical role in plant growth and response to many abiotic stresses. In this study, we identified an important salt-responsive gene, BrRING509 in Brassica rapa. It is localized throughout the plasma membrane and nucleus. The functional results suggest that BrRING509 significantly increases salt stress tolerance in Arabidopsis (Arabidopsis thaliana) transgenic plants. Overexpression of BrRING509 could increase the survival and root length of transgenic seedlings under different salt concentrations. Additionally, ectopic expression of BrRING509 significantly increases the expression level of salt-responsive genes, including AtRD22 and AtRD29A in Arabidopsis transgenic plants subjected to salt stress treatments. The findings of this study indicate that BrRING509 plays a positive role in salt stress tolerance and might be an important candidate gene for the adaptation of Brassica plants in salt-stress environments. |
