Leaf senescence in Arabidopsis thaliana is regulated by a histone H3K4 demethylase (Plant Cell)

Leaf senescence is the final stage of leaf development where the organ turns yellow and programmed cell death occurs. While it is generally understood that the regulation of senescence associated genes (SAGs) is dependent on the trimethylation of histone H3 at lysine 4 (H3K4me3), the exact mechanism…
