RNA-seq data of soybean GFP-GmSRKP1.


ABSTRACT: One fascinating aspect of plant pathogen co-evolution is that pathogens use effectors to alter a broad range of host responses. RNA splicing functions in many physiological processes including plant immunity. However, how plant pathogens manipulate host RNA splicing process remains unknown. Here we demonstrate that PsAvr3c, an avirulence effector from oomycete pathogen Phytophthora sojae, physically binds to and stabilizes soybean (Glycine max) serine/arginine/lysine rich proteins GmSRKPs in vivo. SRKP, novel proteins associating with spliceosome components, are plant susceptibility factors against Phytophthora. Furthermore, RNA-seq data uncovers that differential splicing over one thousand soybean mRNA transcripts, including defense related genes, are significantly changed in GmSRKP1 over-expressing lines. Representative splicing events are verified in either infection assay or soybean transient expression assay. Our results demonstrate that plant pathogen utilize effector to reprogram host RNA splicing, uncovering a new strategy evolved by pathogens to defeat host immune system
