- Abstract
Rubisco small subunit (RbcS), a core component with crucial effects on the structure and kinetic properties of the Rubisco enzyme, plays an important role in response to plant growth, development, and various stresses. Although Rbcs genes have been characterized in many plants, their muti-functions in soybeans remain elusive. In this study, a total of 11 GmRbcS genes were identified and subsequently divided into three subgroups based on a phylogenetic relationship. The evolutionary analysis revealed that whole-genome duplication has a profound effect on GmRbcSs . The cis-acting elements responsive to plant hormones, development, and stress-related were widely found in the promoter region. Expression patterns based on the RT-qPCR assay exhibited that GmRbcS genes are expressed in multiple tissues, and notably Glyma.19G046600 ( GmRbcS8 ) exhibited the highest expression level compared to other members, especially in leaves. Moreover, differential expressions of GmRbcS genes were found to be significantly regulated by exogenous plant hormones, demonstrating their potential functions in diverse biology processes. Finally, the function of GmRbcS8 in enhancing soybean resistance to soybean mosaic virus (SMV) was further determined through the virus-induced gene silencing (VIGS) assay. All these findings establish a strong basis for further elucidating the biological functions of RbcS genes in soybeans.
