Abstract

The co-evolution of plant pathosystems has generated a plethora of molecular mechanisms by which plants defend themselves from the attack of invading pathogens. One of the players involved in plant response to pathogen attack includes the double-stranded RNA Binding (DRB) proteins. The model plant Arabidopsis thaliana encodes DRB proteins by five genes (DRB1 to DRB5). Their participation in plant responses has been demonstrated for viruses and bacteria but not yet for fungi and stramenopiles. Thus, this study investigated the expression profile of A. thaliana DRB genes throughout a time course experiment after inoculation with eukaryotic pathogens of different lifestyles. Employing RT-qPCR and electronic Northern analysis, we observed that DRB genes were differentially expressed between infected and control plants during Alternaria brassicicola, Colletotrichum higginsianum, Phytophtora infestans, Botrytis cinerea, and Golovinomyces orontii infection. DRB3, DRB4, and DRB5 were the genes with higher variation across infected and control plants. Gene expression analysis showed that there is no differentiated pattern between the modulations of DRB genes comparing pathogens with different lifestyles. The results presented in this study are the first approach relating the DRB genes to the response of plants to fungi and oomycetes.
