To get insights into the functional difference of CPD (constitutive photomorphogenesis and dwarfism) between herb and woody plants, a full-length Populus euphratica L. cDNA homologous to Arabidopsis thaliana CPD (AtCPD), named PeCPD, was introduced to Arabidopsis thaliana cpd mutant (CM) and corresponding wild type (WT), resulting in a series of CM-PeCPD and WT-PeCPD transgenic lines. All the CM-PeCPD lines differentially displayed evident restoration in phenotype and fertility compared to cpd mutant, but still showed differences from WT in some respects. All the WT-PeCPD lines displayed obvious overexpression phenotype compared to WT plants. The transcription levels (TLs) of PeCPD in the CM-PeCPD lines were positively correlated, and that in the WT-PeCPD lines uncorrelated, with the level of their phenotype restoration/change. In the CM-PeCPD lines, the TLs of AtDWF4, AtBR6OX2 and AtTCH4 were negatively, and of AtBAS1 and AtSAUR-AC1 positively correlated with PeCPD TLs, whereas in the WT-PeCPD lines, their TLs were uncorrelated, and positively or negatively correlated to PeCPD TLs. The level of total endogenous BRs was basically negatively correlated to the level of phenotype restoration/change and PeCPD TLs in the PeCPD transgenic plants. The findings indicate that PeCPD also plays important role in regulation of plant growth and development through participating in BR biosynthesis.
