Background. VQ proteins, the plant-specific transcription factors, are involved in the regulation of plant growth, development, and stress responses; however, few articles systematic reported VQ genes in the soybean. Methods. In total, we identified 75 GmVQ genes, which were classified into 7 groups (Ⅰ-Ⅶ). Conserved domain analysis indicated that VQ gene family members all contained the VQ domains. The VQ genes from the same evolutionary branches of soybean shared similar motifs and structures. Promoter analysis revealed cis-elements related to stress responses, phytohormone responses and controlling physical and reproductive growth. Based on the RNA-seq and qRT-PCR analysis, GmVQ genes were expressed in nine tissues suggested their putative function in many aspects of plant growth and development, and response to stresses in Glycine max. Results. The present study provided basic information for further analysis of the biological functions of GmVQ proteins in various development processes.
This is a submission to PeerJ for review.
