Valine-glutamine (VQ) proteins are plant-specific proteins that play crucial roles in plant development as well as biotic and abiotic stress responses. genes have been identified in various plants; however, there are no systematic reports in or . Herein, we identified 19 and 32 genes in and , respectively. A total of these genes were divided into eight groups (I-VIII) based on phylogenetic analysis. Gene structure analyses and motif patterns revealed that these genes might have originated from a common ancestor. In silico analyses demonstrated that these genes were expressed in different tissues. qRT-PCR analysis indicated that the genes were differentially regulated during multiple abiotic stresses. This report presents the first systematic analysis of genes from and and provides a solid foundation for further research of the specific functions of VQ proteins.
缬氨酸-谷氨酰胺（VQ）蛋白是植物特有的蛋白，在植物发育以及生物和非生物胁迫响应中发挥关键作用。已在多种植物中鉴定出相关基因；然而，在[具体物种1]或[具体物种2]中尚无系统报道。在此，我们分别在[具体物种1]和[具体物种2]中鉴定出19个和32个VQ基因。基于系统发育分析，这些基因总共被分为八组（I - VIII）。基因结构分析和基序模式表明这些VQ基因可能起源于一个共同祖先。电子分析表明这些VQ基因在不同组织中表达。qRT-PCR分析表明这些VQ基因在多种非生物胁迫下受到差异调控。本报告首次对[具体物种1]和[具体物种2]的VQ基因进行了系统分析，为进一步研究VQ蛋白的特定功能奠定了坚实基础。
