GSNOR-dependent nitric oxide homeostasis shapes methylome persistence after multi-generational exposure to future climate conditions in Arabidopsis thaliana
Environmental stress can modify plant DNA methylation, but the roles of nitric oxide homeostasis in methylome recovery and multigenerational persistence remain unclear. We used whole-genome bisulfite sequencing to compare Arabidopsis thaliana wild type and the GSNOR-deficient mutant (gsnor1-3) exposed to drought, elevated CO2, ozone, heat, or their combination during generation G1 to G3, followed…
