CATALASE2 plays a crucial role in long-term heat tolerance of Arabidopsis thaliana.

Abstract excerpt

Plants are often exposed not only to short-term (S-) heat stress but also to diurnal long-term (L-) heat stress over several consecutive days; nevertheless, most previous studies of heat tolerance have used S-heat stress, such as 42 °C for 30-60 min, for evaluation. Yet the mechanisms underlying L-heat tolerance remain poorly understood. Here we found that hydrogen peroxide (H2O2) in Arabidopsis thaliana plants...
