SUMO in Plants

SUMO is a member of the ubiquitin family and is involved in regulation of protein activity, cellular localization, or protection from ubiquitination. In plants, SUMO plays an important role in biotic and abiotic stress responses, and regulates abscisic acid (ABA) signaling, plant hormone that mediates environmental stress responses, and flowering. In addition, we have found that a functional sumoylation system is essential during seed development, process that is also regulated by ABA at different stages. Our general goal is to investigate the biological role of SUMO in the context of ABA signaling and stress responses in Arabidopsis. For this purpose we will focus on the dissection of the SUMO biological role during seed development and germination, and the identification of new SUMO targets. The data generated will contribute to a better understanding of this biological process and, eventually, to a thoughtful design of plants with improved agronomical traits.
