The plant-specific gene family is one of the largest transcription factor families, participating in plant growth regulation and stress response. Despite extensive characterization in various plants, our knowledge of the family in oat is lacking. Herein, we identified 333 genes from the latest release of the common oat genome. We provide a comprehensive overview of the oat gene family, covering gene structure, chromosomal localization, phylogenetic characteristics, conserved motif compositions, and gene duplications. gene expression in different tissues and the response to various abiotic stresses were characterized using RT-qPCR. The main driver of oat gene family expansion was identified as segmental duplication using collinearity analysis. In addition, the functions of in regulating abiotic stress tolerance in were clarified. This is the first genome-wide investigation of the gene family in cultivated oat, which provided a unique resource for subsequent research to elucidate the mechanisms responsible for oat stress tolerance and provides valuable clues for the improvement of stress resistance in cultivated oat.
植物特有的基因家族是最大的转录因子家族之一，参与植物生长调控和应激反应。尽管在各种植物中已有广泛的特征描述，但我们对燕麦中该家族的了解仍然不足。在此，我们从普通燕麦基因组的最新版本中鉴定出333个该基因。我们对燕麦该基因家族进行了全面概述，涵盖基因结构、染色体定位、系统发育特征、保守基序组成和基因复制。使用RT-qPCR对不同组织中的该基因表达以及对各种非生物胁迫的响应进行了表征。通过共线性分析确定燕麦该基因家族扩张的主要驱动因素是片段重复。此外，还阐明了该基因在调节燕麦非生物胁迫耐受性中的功能。这是对栽培燕麦中该基因家族的首次全基因组研究，为后续阐明燕麦胁迫耐受性机制的研究提供了独特资源，并为提高栽培燕麦的抗逆性提供了有价值的线索。
