A spatio-temporal transcriptomic and proteomic dataset of developing Brassica napus seeds.

Oilseed rape (Brassica napus) seeds are of major economic and nutritional value since they are rich in both oil and proteins, which accumulate predominantly in the embryonic cotyledons during the filling period. Developmental phases such as embryogenesis, seed filling, and maturation have been associated with specific changes in the transcriptional landscape and are controlled by interactions of regulatory components, particularly transcription factors and cis-regulatory elements. However, the global changes on the protein level remain largely elusive. Here, we investigated the dynamics of seed development by an integrative analysis of the seed transcriptome and proteome. Plants of the winter-type cultivar Express 617 were grown under controlled, field-like conditions in the IPK PhenoSphere, and developing seeds were collected for temporally and spatially resolved multi-omics analyses. The dataset covers five stages, from pre-storage to seed maturation, and includes spatial information on four dissected organs/tissues. It provides comprehensive insights into differentiation and developmental processes of the Brassica napus seed and may serve as starting point to select potentially important genes for detailed functional investigations.
