Application

Application Comment Organism
additional information light intensity-dependent degradation of reduced and oxidized porphyrins prevents severe photodynamic leaf damage, moreover, under high-light conditions, elevated contents of reduced and total low-molecular-weight antioxidants, which contribute to the protection against photosensitizing porphyrins Nicotiana tabacum

Protein Variants

Protein Variants Comment Organism
additional information transgenic lines, expression levels of PPOX I mRNA and protein and the cellular enzyme activities are reduced to similar extents in transgenic plants grown under low- or high-light conditions, more necrotic leaf lesions are surprisingly generated under low- than under high-light exposure Nicotiana tabacum

Inhibitors

Inhibitors Comment Organism Structure
acifluorfen necrotic leaf lesions visible within the first hours of light exposure Nicotiana tabacum
additional information antisense RNA expression inhibits the formation of PPOX I in transgenic plants Nicotiana tabacum
