VQ protein is a plant specific protein, which plays an important role in plant growth and development and biological and abiotic stress response. This study aimed to systematically analyze for the first time the of and understand their expression patterns in response to different stimuli. Herein, 44 genes were identified, which were divided into eight groups (I-VIII) based on phylogenetic analysis. Two genes ( and ) could not be located on the chromosome, whereas the remaining genes were randomly distributed on the chromosomes, except for chromosomes 15 and 18. Noteworthy, the main event driving the expansion of the gene family was chromosome fragment duplication. Based on qRT-PCR analysis, genes are expressed in different tissues, and genes are differentially regulated under a variety of abiotic stresses and powdery mildew stress, indicating that they play an important role in plant stress response and other aspects. This report presents the first systematic analysis of genes from and provides a solid foundation for further research of the specific functions of VQ proteins.
VQ 蛋白是一种植物特异性蛋白，在植物生长发育以及生物和非生物胁迫响应中发挥重要作用。本研究首次旨在对 VQ 蛋白进行系统分析，以深入了解其在不同刺激下的表达模式。在此，共鉴定到 44 个基因，这些基因可根据系统发育分析分为八个组（I-VIII）。两个基因（和）无法定位到染色体上，而其余基因除了染色体 15 和 18 之外，随机分布在其余染色体上。值得注意的是，导致 VQ 基因家族扩张的主要事件是染色体片段重复。基于 qRT-PCR 分析，基因在不同组织中表达，基因在多种非生物胁迫和白粉病胁迫下差异调控，表明它们在植物胁迫响应和其他方面发挥重要作用。本报告首次对来自的 VQ 基因进行了系统分析，为进一步研究 VQ 蛋白的特定功能提供了坚实的基础。
