resistance protein-associated defense signaling. Although the roles of SAG101, EDS1, and
PAD4 in biotic stress have been extensively studied, little is known about their functions in
plant responses to abiotic stresses. Here, we show that SAG101, EDS1, and PAD4 are
involved in the regulation of freezing tolerance in Arabidopsis. With or without cold
acclimation, the sag101, eds1, and pad4 single mutants, as well as their double mutants …
