Early production and scavenging of hydrogen peroxide in the apoplast of sunflower plants exposed to ozone

Early production and scavenging of hydrogen peroxide in the apoplast of sunflower plants exposed to ozone

The present work set out to define the processes involved in the early O3-induced H2O2 accumulation in sunflower plants exposed to a single pulse of 150 ppb of O3 for 4 h. Hydrogen peroxide accumulation only occurred in the apoplast and this temporally coincided with the fumigation period. The inhib...
