Here’s an interesting new paper on ROS1, an enzyme that removes DNA methylation and that is POSITIVELY controlled by DNA methylation.
It’s repression during heat stress 🥵🌱 is crucial to suppress transposon mobility! 🧬

Plants repress ROS1 expression to attenuate heat-induced transposon burst - Nature Plants
Plants suppress the DNA demethylase ROS1 under heat stress to limit transposon activation, preventing genome instability. This conserved mechanism balances stress adaptation with genome protection.
