Multi-omics analysis of seed oil accumulation in Brassica napus cultivars ZS11 and WH5557

This project aims to elucidate the molecular mechanisms regulating seed oil accumulation in Brassica napus through transcriptomic analysis. Developing seeds of two contrasting cultivars, high-oil ZS11 (approximately 48% oil content) and low-oil WH5557 (approximately 32% oil content), were collected at three key developmental stages: 10, 24, and 34 days after flowering (DAF). A total of 18 samples (3 biological replicates per cultivar per time point) were sequenced using Illumina platform. This dataset provides a comprehensive resource for understanding oil biosynthesis in rapeseed and for genetic improvement of oil content.
