We collected genome-wide expression data from three subspecies and normalized them by FPKM. The tissues used in the study were collected throughout the flowering process of the rape plant from eight representative accessions. T0: 24 days post sowing; T1: 54 days post sowing; T2: 82 days post sowing; T3: 115 days post sowing; T4: 147 days post sowing. An instruction download about tissues stage is available via FTP.
