As an important oil crop in the world, Brassica napus occupies a key position in agricultural production and industrial applications due to its excellent oil accumulation capacity and wide ecological adaptability. This study systematically expounded the molecular mechanism of gene expression regulation in this crop, focusing on its regulatory network in growth and development and environmental stress response. Studies have shown that transcription factor families such as MYB, bHLH and WRKY finely regulate the adaptive response of rapeseed to abiotic stresses such as high temperature, low temperature and drought through complex synergistic effects. At the same time, epigenetic mechanisms such as DNA methylation and histone modification constitute the second guarantee system for gene expression regulation. High-throughput omics technology and CRISPR/Cas9 genome editing technology have successfully revealed key gene networks related to stress resistance, seed development and flowering regulation. However, due to the special complexity of the allotetraploid genome of Brassica napus and the intricate interactions between growth and development and stress response pathways, related research still faces many challenges. This study emphasizes that by integrating multi-omics analysis methods and synthetic biology strategies to establish a precise gene regulation system, it will provide a theoretical basis and technical support for breeding new rapeseed varieties with high and stable yields. This study not only has guiding significance for the genetic improvement of Brassica napus, but also provides a reference for the stress-resistant breeding of other important crops.
