Histone H3K4 methyltransferases SDG25 and ATX1 maintain heat?stress gene expression during recovery in Arabidopsis

Plants have short-term stress memory that enables them to maintain the expression state of a substantial subset heat-inducible genes during recovery after heat stress. Little is known about molecular mechanisms controlling stress-responsive gene at stage in plants, however. In this article, we demonstrate histone H3K4 methyltransferases SDG25 and ATX1 are required for heat-stress tolerance Arabidopsis. not only important stress, but also maintaining recovery. A combination whole-genome bisulfite sequencing, RNA-sequencing ChIP-qPCR demonstrated mutations decrease H3K4me3 levels, increase DNA cytosine methylation inhibit results confirm binds chromatins associated with these target genes. Our reveal affects regions loci recovery, providing insights into transcriptional plants.
