Pre-mRNA Splicing in Plants: In Vivo Functions of RNA-Binding Proteins Implicated in the Splicing Process
Meyer K, Köster T, Staiger D. Pre-mRNA Splicing in Plants: In Vivo Functions of RNA-Binding Proteins Implicated in the Splicing Process. Biomolecules. 2015;5(3):1717-1740.Alternative pre-messenger RNA splicing in higher plants emerges as an important layer of regulation upon exposure to exogenous and endogenous cues. Accordingly, mutants defective in RNA-binding proteins predicted to function in the splicing process show severe phenotypic alterations. Among those are developmental defects, impaired responses to pathogen threat or abiotic stress factors, and misregulation of the circadian timing system. A suite of splicing factors has been identified in the model plant Arabidopsis thaliana. Here we summarize recent insights on how defects in these splicing factors impair plant performance

RNA-Binding Protein Immunoprecipitation from Whole-Cell Extracts
Köster T, Staiger D. RNA-Binding Protein Immunoprecipitation from Whole-Cell Extracts. Methods in molecular biology (Clifton, N.J.). 2014;1062:679-695.RNA-based regulation is increasingly recognized as an important factor shaping the cellular transcriptome. RNA-binding proteins that interact with cis-regulatory motifs within pre-mRNAs determine the fate of their targets. Understanding posttranscriptional networks controlled by an RNA-binding protein requires the identification of its immediate in vivo targets. Here we describe RNA immunoprecipitation in Arabidopsis thaliana. Transgenic plants expressing an RNA-binding protein fused to green fluorescent protein are treated with formaldehyde to "trap" RNAs in complexes with their physiological protein partners. A whole-cell extract is subjected to immunoprecipitation with an antibody against the GFP tag. In parallel, a mock immunoprecipitation is performed using an unrelated antibody. Coprecipitated RNAs are eluted from the immunoprecipitate and identified via real-time PCR. Enrichment relative to immunoprecipitation from plants expressing GFP only and mock immunoprecipitation with an unrelated antibody indicates specific binding
