Insights into the transcriptional and posttranscriptional regulation of the rice SUMOylation machinery and into the role of two rice SUMO proteases

SUMOylation is an essential eukaryotic post-translation modification that, in plants, regulates numerous cellular processes, ranging from seed development to stress response. Using rice as a model crop plant, we searched for potential regulatory points that may influence the activity of the rice SUMOylation machinery genes.
