Cover Caption: Ubiquitination and Sumoylation


This Special Issue focuses on protein ubiquitination and Sumoylation in plants. On the cover, we have used a cartoon of a Japanese sumo wrestler to represent Small Ubiquitinlike Modifier (SUMO) proteins, which are the same proteins in Sumoylation. The box has ‘F-BOX’ printed on it, which is a reference to the F-box proteins in ubiquitination. Likewise, the golden ring refers to RING finger proteins (cover design by Qi Xie and Ying Wang).
