|Abstract||Invasive plant pathogens have developed the ability to modify metabolic processes of their host and to promote those which facilitate their growth at the expense of the host. SUMOylation is widely conserved posttranslational modification in eukaryotic organisms, and this process exerts pleiotropic functional consequences that include changes in many aspects of protein activities, functions, stability, localization and interactions with other partners. Here we provide experimental evidence indicating that the SUMO pathway is partially under transcriptional control in Phythopthora infestans infected Solanum tuberosum leaves. We also report the results of using a recently developed proteomic approach based on the use of 3D gels to identify the endogenous SUMO targets and we show that during the infection process the abundance of most of these conjugates either increases, or decreases, significantly. This study primes further investigations into the molecular connections between host SUMOylation and Phythopthora infestans infection.|
