Project description:In this project, we developed a data resource based on the German winter oilseed rape cultivar Express 617. Plants were grown under controlled environmental conditions in the container-based system of the IPK PhenoSphere in 2020-2021. The dataset comprises gene expression data generated by RNA sequencing of different seed tissues across five stages of seed development, spanning early embryo/seed development, seed filling, and seed maturation. In the first stage (pre-storage), whole seeds were analysed. In the later four stages, developing seeds were dissected into four organs/tissues (SC = seed coat, IC = inner cotyledon, OC = outer cotyledon, and RA = radicle). This dataset (mRNA sequencing) is part of a series of multi-omics data generated in the frame of the AVATARS project.
