Coordinated regulation of pre-mRNA splicing by the SFPS-RRC1 complex to promote photomorphogenesis in Arabidopsis
We report the application of illumina high throughput RNA sequencing for rrc1-3 mutants in both light and dark conditions(three replicates under each condition) in Arabidopsis. By obtaining over 100 million reads (150bp paired_end) for each rRNA depleted lib, we compared the transcriptome profile between rrc1-3 mutant and Col-0 wild type light and dark conditions. We find that genome wide spliciing activities are general defective in rrc1-3 mutant comparing to Col-0 wild type, which indicates the importance of post-transcriptional processing on gene expression regulation. In addition, the sequencing data also indicates light signal probably regulates both splicing cascade and transcriptional cascade to control the downstream gene expression. Overall design: Examination of splicing profile in rrc1-3 mutants, comparing with Col-0 wild type under both light and dark conditions.
