“…VQs has been reported to interact with WRKY TFs and to regulate a variety of physiological and biochemical processes and abiotic stress responses [ 6 , 9 , 11 , 49 , 50 ]. Here, by constructing co-expression and an Arabidopsis associated model, multiple Gossypium VQs , such as GhVQ37 , GhVQ59 , and GhVQ83 , were predicted to interact with different WRKY TFs, implying that VQs act in stress tolerance through interacting with WRKYs.…”

Background Valine-glutamine (VQ) motif-containing proteins play important roles in plant growth, development and abiotic stress response. For many plant species, the VQ genes have been identified and their functions have been described. However, little is known about the origin, evolution, and functions (and underlying mechanisms) of the VQ family genes in cotton. Results In this study, we comprehensively analyzed the characteristics of 268 VQ genes from four Gossypium genomes and found that the VQ proteins evolved into 10 clades, and each clade had a similar structural and conservative motif. The expansion of the VQ gene was mainly through segmental duplication, followed by dispersal. Expression analysis revealed that many GhVQs might play important roles in response to salt and drought stress, and GhVQ18 and GhVQ84 were highly expressed under PEG and salt stress. Further analysis showed that GhVQs were co-expressed with GhWRKY transcription factors (TFs), and microRNAs (miRNAs) could hybridize to their cis-regulatory elements. Conclusions The results in this study broaden our understanding of the VQ gene family in plants, and the analysis of the structure, conserved elements, and expression patterns of the VQs provide a solid foundation for exploring their specific functions in cotton responding to abiotic stresses. Our study provides significant insight into the potential functions of VQ genes in cotton.

“…Recently, MdVQ10 and MdVQ15 were also described to interact with MdWRKY52 to regulate pathogen defense and development in apple ( Malus domestica Borkh ) [ 10 ]. In addition, OsVQ7 interacts with OsWRKY24 and play roles in NO signaling contributing to the tolerance of various stresses and development in rice ( Oryza sativa ) [ 11 ].…”

When rice gets the chills: comparative transcriptome profiling at germination shows WRKY transcription factor responses

et al. 2021

Rice is vital for food security. Due to its tropical origin, rice suffers from cold temperatures that affect its entire life cycle. Key genes have been identified involved in cold tolerance. WRKYs are generally downstream of the MAPK cascade and can act together with VQ proteins to regulate stress-responsive genes.• Chilling treatment was applied at germination to two rice genotypes (tolerant and sensitive). Shoots at S3 stage were collected for RNA-seq to identify OsWRKY, OsMAPKs and OsVQs expression. Relationships among MAPKs, WRKYs and VQs were predicted through correlation analysis. OsWRKY transcriptional regulation was predicted by in silico analysis of cis-regulatory elements.• A total of 39 OsWRKYs were differentially expressed. OsWRKY21, OsWRK24 and OsWRKY69 are potential positive regulators, while OsWRKY10, OsWRK47, OsWRKY62, OsWRKY72 and OsWRKY77 are potential negative regulators, of chilling tolerance. 12 OsMAPKs were differentially expressed. OsMAPKs were downregulated and negatively correlated with the upregulated OsWRKYs in the tolerant genotype. 19 OsVQs were differentially expressed, three and six OsVQs were positively correlated with OsWRKYs in the tolerant and sensitive genotypes, respectively. Seven differentially expressed OsWRKYs have cold-responsive elements in their promoters and five upregulated OsWRKYs in the tolerant genotype contained the Wbox motif.• Chilling causes changes in OsWRKY, OsMAPK and OsVQ gene expression at germination. OsWRKYs may not act downstream of the MAPK cascade to coordinate chilling tolerance, but OsWRKYs may act with VQs to regulate chilling tolerance. Candidate OsWRKYs are correlated and have a W-box in the promoter, suggesting an autoregulation mechanism.
