Arabidopsis JMJ heat project
The acclimation to relatively high temperature enables plants to tolerate to subsequent lethal high temperatures. Although much progress has been made toward epigenetic regulation of gene expression in plants, how plants memorize environmental changes over several days in a flexible and reversible manner remains unclear. We found that demethylases of tri-methylation of lysine 27 on histone H3 (H3K27me3), JUMONJI (JMJ) family proteins are required and sufficient for heat acclimation in Arabidopsis.
