. Compared with wild-type CCMC, CsDWF1 had lower expression levels in the stem, leaf and ovary of cpa-2. In addition, the compact phenotype in cpa-2 could be partially restored by exogenous BR application. Transcriptome analysis revealed that many genes related to plant growth hormones were differentially expressed in cpa-2 plants. This is the first report about the characterization and cloning of the CsDWF1 gene. This work revealed the importance of CsDWF1 in plant development regulation and extended our understanding of the interaction between BRs and other hormones for plant architecture development.
