ProteomicsSUMOylome Profiling in Arabidopsis of Targets Modified by the Sumo Ligase Siz1 During Heat Stress
Ligation is accomplished by a small set of SUMO E3 ligases, with the SAP-MIZ domain-containing (SIZ)-1 and METHYL METHANESULFONATE-SENSITIVE (MMS)-21 ligases having critical roles in stress protection and DNA endoreduplication, respectively. To help identify their corresponding Arabidopsis targets,...

TranscriptomicsSUMO E3 ligase SIZ1 sustains nuclear condensate-mediated immune activation in plants
SIZ1, a major plant SUMO E3 ligase, has diverse roles in development and immunity. Although loss-of-function studies have positioned SIZ1 as a negative immune regulator, the pleiotropic effects of its broad substrate repertoire may obscure its core function. Here we report that SIZ1 overaccumulation...

TranscriptomicsGenome-wide transcriptome analysis of Arabidopsis and siz1-3 response to drought stress
Post-translational modifications of proteins by Small Ubiquitin-like Modifiers (SUMOs) regulate protein degradation and localization, protein-protein interaction, and transcriptional activity. SUMO E3 ligase functions are executed by SIZ1/SIZ2 in yeast and PIAS family members in human. The Arabidops...

Methylation profilingSIZ1-mediated SUMOylation of ROS1 Enhances Its Stability and Positively Regulates Active DNA Demethylation in Arabidopsis
The 5-methylcytosine DNA glycosylase/lyase REPRESSOR OF SILENCING 1 (ROS1)-mediated active DNA demethylation is critical for shaping the genomic DNA methylation landscape in Arabidopsis. Whether and how the stability of ROS1 may be regulated by post-translational modifications is unknown. Using a me...
