General Information

General Information Comment Organism
malfunction a reduction in enzyme expression results in greater photosensitivity Arabidopsis thaliana
physiological function the endogenous level of the enzyme is rate-limiting for non-photochemical quenching in Arabidopsis under subsaturating but not saturating light and can become rate-limiting under chilling conditions Arabidopsis thaliana
