Differential genes of Arabidopsis thaliana in response to Ustilago maydis infection

Abstract

Arabidopsis thaliana - Ustilago maydis integrate the pathosystem used to study the plant-pathogen interaction, in order to know the molecular mechanisms involved in the response of the plant to the pathogenesis of U. maydis, a differential expression bank was constructed 72 hours after inoculation, using the subtractive hybridization technique. The fragments obtained were sequenced and subjected to bioinformatic analysis which allowed us to locate 36 different sequences with homology to Arabidopsis thaliana in response to U. maydis infection, several of them with roles in photosynthesis, reactive oxygen species, defense, and signaling among others, involved either directly or indirectly in the early response to infection. The results of this work are focused on understanding the plant-pathogen interaction and can be extrapolated to other model plants of agronomic importance.
