Brassica rapa subsp. chinensis Raw sequence reads

The branching is an important trait for controlling the architecture of Chinese flowering cabbage. Gibberellins are growth phytohormones that regulate branching and promote stem elongation in plants. We obtained a DH line designated CX020 showed a multi-branched (MB) phenotype isolated by microspore culture in Chinese flowering cabbage. After application of 600 mg/L GA3 on MB, the number of primary rosette branching was significantly decreased, however, the regulatory mechanisms were not well known. RNA-sequencing (RNA-seq) and metabolic profiling were performed to analyse controlling the genes responding for the GA regulation of branching architecture and hormone content changes in MB and MB_GA (exogenous application of GA3 on MB).
