The histone deacetylase SRT2 enhances the tolerance of chrysanthemum to low temperatures through the ROS scavenging system.

Low temperatures can severely affect plant growth and reduce their ornamental value. A family of plant histone deacetylases allows plants to cope with both biotic and abiotic stresses. In this study, we screened and cloned the cDNA of DgSRT2 obtained from transcriptome sequencing of chrysanthemum leaves under low-temperature stress.
