This study investigates how glutathione mediates plant responses to high-temperature stress, showing its role in redox regulation and adaptation to heat.

The paper measures chromatin mobility in Arabidopsis thaliana during DNA damage and finds that the DDR factor SOG1 increases mobility, which is reduced in sog1-1 mutants.

The paper introduces ANCHOR, a method to monitor single-locus positioning in plant cells, and uses it to study chromatin mobility during cell differentiation in Arabidopsis.

This study shows that reducing rRNA gene copies in Arabidopsis leads to genomic instability, chromosomal duplications, and altered gene expression, including enhanced resistance to pathogens.
