1 Here, we report that a deficiency in the H2O2-scavenging enzyme, cytosolic ascorbate peroxidase (APX1), results in the accumulation of H2O2 in Arabidopsis plants grown under optimal conditions. Hydrogen Peroxide ascorbate peroxidase 1 Arabidopsis thaliana
2 Here, we report that a deficiency in the H2O2-scavenging enzyme, cytosolic ascorbate peroxidase (APX1), results in the accumulation of H2O2 in Arabidopsis plants grown under optimal conditions. Hydrogen Peroxide ascorbate peroxidase 1 Arabidopsis thaliana
3 Our findings also suggest that at least part of the induction of heat shock proteins during light stress in Arabidopsis is mediated by H2O2 that is scavenged by APX1. Hydrogen Peroxide ascorbate peroxidase 1 Arabidopsis thaliana
