physiological function | violaxanthin de-epoxidase plays an important role in protecting the photosynthetic apparatus from photo-damage by dissipating excessively absorbed light energy as heat, via the conversion of violaxanthin (V) to intermediate product antheraxanthin and final product zeaxanthin under high light stress | Cucumis sativus |
