The study used 80 genes ( genes) in rapeseed, which were identified and designated with nomenclature based on their chromosomal locations. A systematic analysis encompassed the evolutionary relationships, classifications, gene structures, motif compositions, chromosome localization, and gene replication events within these genes. These 80 BnTCP proteins were categorized into three subfamilies, with the PCF subfamily showing significant expansion during evolution. Segmental duplications were identified as a major driver of TCP family amplification. To comprehensively assess the evolutionary relationships of the TCP family across diverse plant species, nine comparative genomic maps were constructed, elucidating homologous genes between and representative monocotyledonous and dicotyledonous plants. In the final phase of the study, the gene expression response characteristics of 15 selected genes across various biological processes and stress responses were examined. Noteworthy candidates, including , , and , were identified as potentially crucial in tissue development and environmental stress responses.

该研究使用了油菜中的80个基因，这些基因根据其染色体位置进行了鉴定和命名。系统分析涵盖了这些基因的进化关系、分类、基因结构、基序组成、染色体定位和基因复制事件。这80个BnTCP蛋白被分为三个亚家族，其中PCF亚家族在进化过程中表现出显著扩张。片段重复被确定为TCP家族扩增的主要驱动力。为了全面评估TCP家族在不同植物物种中的进化关系，构建了九张比较基因组图谱，阐明了油菜与代表性单子叶植物和双子叶植物之间的同源基因。在研究的最后阶段，研究了15个选定基因在各种生物过程和应激反应中的基因表达响应特征。值得注意的候选基因，包括[具体基因1]、[具体基因2]和[具体基因3]，被确定在组织发育和环境应激反应中可能至关重要。
