Abstract

Caffeic acid O-methyltransferase (COMT) is a multifunctional enzyme involved in lignin biosynthesis and plays an important role in various primary and secondary metabolic pathways, including the plant stress response. In this study, we identified 37 genes from the oat () whole-genome database, which are distributed across 11 chromosomes. Phylogenetic analysis grouped these genes into two major subfamilies, indicating that they are highly conserved during evolution and share close relationships with genes from and . Cis-acting elements analysis revealed a rich presence of regulatory motifs related to plant hormone signaling and stress responses. Expression profiling of different oat varieties infected with powdery mildew and leaf spot disease showed significant upregulation or downregulation of several genes (e.g., , , , ). Moreover, disease-resistant oat varieties have higher lignin contents compared to susceptible varieties. Overexpression of and in tobacco leaves resulted in significantly increased lignin content, highlighting the potential of these genes in lignin biosynthesis. These results offer a preliminary exploration of the role of in both lignin synthesis and the plant stress response, laying the groundwork for further functional studies and potential applications in oat breeding.

摘要

咖啡酸O-甲基转移酶（COMT）是一种参与木质素生物合成的多功能酶，在包括植物应激反应在内的各种初级和次级代谢途径中发挥重要作用。在本研究中，我们从燕麦（）全基因组数据库中鉴定出37个基因，这些基因分布在11条染色体上。系统发育分析将这些基因分为两个主要亚家族，表明它们在进化过程中高度保守，并且与来自和的基因关系密切。顺式作用元件分析揭示了与植物激素信号传导和应激反应相关的调控基序丰富存在。对感染白粉病和叶斑病的不同燕麦品种进行表达谱分析，结果显示几个基因（如、、、）显著上调或下调。此外，抗病燕麦品种的木质素含量高于感病品种。在烟草叶片中过表达和导致木质素含量显著增加，突出了这些基因在木质素生物合成中的潜力。这些结果为在木质素合成和植物应激反应中的作用提供了初步探索，为燕麦育种中的进一步功能研究和潜在应用奠定了基础。
