| Résumé: | Copyright © 2025 Elsevier Masson SAS. All rights reserved. Brassica napus is one of the major oil-seed crops worldwide, providing a large proportion of the global edible oil supply. The root system of B. napus is essential for nutrient and water uptake, contributing significantly to the yield formation. However, the lack of comprehensive understanding in root development mechanism has hindered the improvement of root system in B. napus. In this study, we evaluated the root system of 20 representative B. napus accessions by assessing the primary and lateral root growth at the seedling stage, and the accessions with well-developed and less-developed root system, namely 'Sy28' and 'Gl210', were identified and subjected to transcriptome analysis. Gene Ontology analysis revealed several biological processes closely related to root development, including phytohormone response, cell cycle progression, and cell wall organization. Subsequently, a series of differentially expressed genes (DEGs) related to the development of meristematic and elongation zone in primary root, as well as lateral root development were identified by heatmap analysis. Furthermore, we verified the function of two selected DEGs, BnaA06.CIPK25 and BnaA08.AGL21, in the control primary root elongation and lateral root development, respectively. These findings offer new insights into the regulatory mechanisms governing root development in B. napus |
