Contrasting epigenetic dynamics in chromosome arms and pericentromeres during ROS1-induced plant immune memory

Adam Hannan Parker, Peijun Zhang, Kwok Yin Man, Louis Tirot, Stephen A. Rolfe, Lisa M. Smith, Samuel W. Wilkinson, Jurriaan Ton

This study shows that ROS1-induced DNA demethylation leads to distinct epigenetic changes in chromosome arms and pericentromeres during plant immune memory formation and erasure.

Multi-generational biotic stress increases the rate of spontaneous epimutations in a ROS1-dependent manner

Zhilin Zhang, Adam Hannan Parker, Aikaterini Symeonidi, Samuel W. Wilkinson, J. H. M. Stassen, Lisa M. Smith, Jurriaan Ton, Frank M. Johannes

The paper shows that multi-generational exposure to biotic stress increases epimutation rates in Arabidopsis, mediated by ROS1, affecting low-methylation genes.
