Transcriptome Analysis of Alternative Splicing Events Induced by Arbuscular Mycorrhizal Fungi (Rhizophagus irregularis) in Pea (Pisum sativum L.) Roots.

ABSTRACT: Alternative splicing (AS), a process that enables formation of different mRNA isoforms due to alternative ways of pre-mRNA processing, is one of the mechanisms for fine-tuning gene expression. Currently, the role of AS in symbioses formed by plants with soil microorganisms is not fully understood. In this work, a comprehensive analysis of the transcriptome of garden pea (Pisum sativum L.) roots in symbiosis with arbuscular mycorrhiza was performed using RNAseq and following bioinformatic analysis. AS profiles of mycorrhizal and control roots were highly similar, intron retention accounting for a large proportion of the observed AS types (67%). Using three different tools (SUPPA2, DRIMSeq and IsoformSwitchAnalyzeR), eight genes with AS events specific for mycorrhizal roots of pea wer
