RNA-seq of pericarp of purple-grain wheat Luozhen No.1 of 20 days (D20) shading treatment after pollination, against 20 DAP untreated controls

Purple-grain wheat are caused by anthocyanin accumulation in the seed coat. The anthocyanin biosynthesis and accumulation were affected by light in purple-grain wheat. The spikes of purple-grain wheat Luozhen No.1 were bagged with four-layer Kraft paper bags after pollination. To identify genes involved in the anthocyanin biosynthesis, we sequenced two pericarp cDNA libraries, D20 (20 DAP) of shading treatment, and L20 (20 DAP) of untreated control using an Illumina HiSeqTM 2000.
