Abstract

The Cellulose Synthase gene (CS) superfamily and COBRA-like (COBL) gene family are essential for synthesizing cellulose and hemicellulose, which play a crucial role in cell wall biosynthesis and the hardening of plant tissues. Our study identified 126 ZbCS and 31 ZbCOBL genes from the Zanthoxylum bungeanum (Zb) genome. Phylogenetic analysis and conservative domain analysis unfolded that ZbCS and ZbCOBL genes were divided into seven and two subfamilies, respectively. Gene duplication data suggested that more than 75% of these genes had tandem and fragment duplications. Codon usage patterns analysis indicated that the ZbCS and ZbCOBL genes prefer ending with A/T base, with weak codon preference. Furthermore, seven key ZbCS and five key ZbCOBL genes were identified based on the content of cellulose and hemicellulose and the expression characteristics of ZbCS and ZbCOBL genes in various stages of stipule thorns. Altogether, these results improve the understanding of CS and COBL genes and provide valuable reference data for cultivating Zb with soft thorns.

Zanthoxylum bungeanum 托叶刺纤维素合成酶超家族和 COBRA 样基因家族的基因组调查与表达分析

摘要纤维素合成酶基因（CS）超家族和类 COBRA 基因（COBL）家族是合成纤维素和半纤维素的关键基因，在细胞壁生物合成和植物组织硬化中起着至关重要的作用。我们的研究从Zanthoxylum bungeanum（Zb）基因组中鉴定出126个ZbCS基因和31个ZbCOBL基因。系统进化分析和保守结构域分析显示，ZbCS 和 ZbCOBL 基因分别分为 7 个亚科和 2 个亚科。基因重复数据表明，75%以上的基因存在串联和片段重复。密码子使用模式分析表明，ZbCS 和 ZbCOBL 基因偏好以 A/T 碱基结尾，密码子偏好性较弱。此外，根据托叶刺中纤维素和半纤维素的含量以及ZbCS和ZbCOBL基因在不同阶段的表达特征，确定了7个关键ZbCS基因和5个关键ZbCOBL基因。总之，这些结果增进了人们对CS和COBL基因的了解，为栽培软刺浙贝母提供了宝贵的参考数据。
