摘要： In rice, OsBBX14, a B-box (BBX) transcription factor, reportedly delays heading. Here, we revealed that OsBBX14 positively regulates rice photomorphogenesis. The OsBBX14-overexpressing (OsBBX14-OX) seedlings were hypersensitive to light, especially blue light, and exhibited dwarfism, while the OsBBX14 knock-out plants (osbbx14) were taller than wild-type plants under blue light. Histological analyses indicated that the observed dwarfism was mainly due to decreased cell length. Additionally, OsBBX14 abundance (mRNA and protein levels) was influenced by different light wavelengths in a time-dependent manner. The expression levels of HY5Ls (LONG HYPOCOTYL 5 LIKE) and ELIPs (EARLY LIGHT-INDUCIBLE PROTEIN) genes, whose Arabidopsis thaliana homologs function as positive regulators in the light signaling pathway, were significantly upregulated in OsBBX14-OX lines. In contrast, the expression of genes related to cell wall organization and dwarfism was downregulated in OsBBX14-OX lines. Chromatin immunoprecipitation (ChIP) assays confirmed that OsBBX14 binds to the T/G-box of HY5L1 (LONG HYPOCOTYL 5 LIKE 1) promoter. LUC complementation imaging (LCI) results suggested that OsBBX14 had physical interaction with OsCRY2 protein. Collectively, in response to blue light, OsBBX14 promotes photomorphogenesis, probably by directly or indirectly regulating the expression of HY5L1 or other genes related to cell wall organization and dwarfism.
