red chlorophyll catabolite + reduced acceptor Arabidopsis thaliana chlorophyll catabolism, leaf senescence, ring-opening activity, a reduction destroys the residual conjugated bond system to yield the colourless product primary fluorescent chlorophyll catabolite + oxidized acceptor pFCC, the fate of primary fluorescent chlorophyll catabolite is to be conjugated, imported into the vacuole and tautomerized to accumulate there as non-fluorescent chlorophyll catabolites and possibly other terminal catabolites ?
