Other claims from this paper (9)
- Intervention effect Supplementary UVB radiation reduced transcripts of the photosynthetic genes Lhcb and psbA in fully expanded pea leaves.
- Association The UVB-induced response of photosynthetic transcripts was less marked in apical buds.
- Association High light ameliorated the UVB-induced response of photosynthetic transcripts.
- Intervention effect Free radical generators mimicked the effect of UVB on pea leaves.
- Intervention effect Antioxidant feeding prevented the effect of UVB on pea leaves.
- Intervention effect UVB irradiation increased the activities of ascorbate peroxidase, glutathione reductase and superoxide dismutase in pea.
- Association Antioxidant enzyme activities were higher under high light and in buds.
- Mechanism Active oxygen species are involved in the UVB signal pathway leading to down-regulation of photosynthetic genes in pea.
- Mechanism The antioxidant capacity of pea tissue may determine how susceptible these transcripts are to UVB radiation.
