The TRM (TONNEAU1 Recruiting Motif) gene family plays a crucial role in multiple biological processes, including microtubule organization, cell division regulation, fruit morphogenesis, stress adaptation, and growth and development. To delve deeper into the potential functions of BnaTRMs in Brassica napus, this study employed bioinformatics methods to systematically identify and analyze the TRM family genes in Brassica napus (Westar). Using the model plant Arabidopsis thaliana as a reference and based on six conserved motifs, 100 TRM members were first identified in Brassica napus. These genes are widely distributed across 19 chromosomes, and most exhibit nuclear localization characteristics. Through gene collinearity analysis among Brassica napus, Arabidopsis thaliana, Glycine max, Oryza sativa, and Zea mays, we speculate that Brassica napus and Glycine max may share a similar evolutionary history. Analysis of cis-acting elements in the 2000 bp upstream region of TRM gene promoters revealed numerous elements related to abiotic stress response and hormone regulation. Furthermore, qRT-PCR data supported these findings, indicating that multiple TRM genes actively participate in the growth and development process and abiotic stress tolerance of Brassica napus. In summary, BnaTRMs exhibit significant functions in stress adaptation, growth, and development. This study not only enhances our understanding of the functions of the TRM gene family but also provides new perspectives and strategies for further exploring their regulatory mechanisms and potential applications.
