The paper identifies FUG1, AL3, and LHP1 as essential components for repeat-expansion induced epigenetic silencing in Arabidopsis thaliana.

This study shows that sumoylation is largely dispensable for normal yeast growth but essential for heat tolerance, as reduced Ubc9 activity leads to temperature sensitivity and transcriptional dysregulation.

The paper shows that ethanol stress increases sumoylation of Cst6, which stabilizes the protein and restricts expression of its target genes.
