SKIP Confers Salt Tolerance through Controlling Gene Alternative Splicing in Arabidopsis

ABSTRACT: A better understanding of the mechanisms for plant in response to abiotic stresses is key for the improvement of plant to resistant to the stresses. Much has been known for the regulation of gene expression in response to salt stress at transcriptional level, however, little is known at posttranscriptional level for this response. Recently, we identified that SKIP is a component of spliceosome and is necessary for the regulation of alternative splicing and mRNA maturation of clock genes. In this study, we observed that skip-1 is hypersensitive to salt stress. SKIP is necessary for the alternative splicing and mRNA maturation of several salt tolerance genes, e.g. NHX1, CBL1, P5CS1, RCI2A, and PAT10. Genome-wide analysis reveals that SKIP mediates the alternative splicing of many genes under
