摘要 | Light is a key environmental signal that regulates plant growth and development. While posttranscriptional regulatory mechanisms of gene expression include alternative splicing (AS) of pre-messenger RNA (mRNA) in both plants and animals, how light signaling affects AS in plants is largely unknown. Here, we identify DExD/H RNA helicase U2AF65-associated protein (UAP56) as a negative regulator of photomorphogenesis in Arabidopsis thaliana. UAP56 is encoded by the homologs UAP56a and UAP56b. Knockdown of UAP56 led to enhanced photomorphogenic responses and diverse developmental defects during vegetative and reproductive growth. UAP56 physically interacts with the central light signaling repressor constitutive photomorphogenic 1 (COP1) and U2AF65. Global transcriptome analysis revealed that UAP56 and COP1 co-regulate the transcription of a subset of genes. Furthermore, deep RNA-sequencing analysis showed that UAP56 and COP1 control pre-mRNA AS in both overlapping and distinct manners. Ribonucleic acid immunoprecipitation assays showed that UAP56 and COP1 bind to common small nuclear RNAs and mRNAs of downstream targets. Our study reveals that both UAP56 and COP1 function as splicing factors that coordinately regulate AS during light-regulated plant growth and development. The RNA helicase UAP56 and the E3 ubiquitin ligase COP1 function as splicing factors to coordinately regulate alternative splicing during light-regulated plant growth and development. |
