Abstract excerpt

Photosynthetic light reactions comprise a significant source of hydrogen peroxide (H(2)O(2)) in illuminated leaves. APXs (ascorbate peroxidases) reduce H(2)O(2) to water and play an important role in the antioxidant system of plants. In the present study we addressed the significance of chloroplast APXs in stress tolerance and signalling in Arabidopsis thaliana. To this end, T-DNA (transfer DNA) insertion mutants...
