General Information

General Information	Comment	Organism
evolution	evolutionary tree of vascular plants based on analysis of several molecular data sets for enzymes RCCR, overview. RCCR-1 appears to have evolved independently in some unrelated lineages. It has a restricted phylogenetic distribution and most likely represents recent derivations from RCC-2. Two forms of primary fluorescent chlorophyll catabolite, pFCC, are found in plants, the slightly more polar pFCC-1 or the less polar pFCC-2. A third form, pFCC-3 is found only in basal pteridophytes and in some gymnosperms, it seems to be produced by an ancestral type of RCCR. RCCR-1 appears to have evolved independently in some unrelated lineages. It has a restricted phylogenetic distribution and most likely represents recent derivations from RCCR-2. The situation within monocots appears to be quite clear cut. All the grasses and Carex tested are characterized by type 1 of RCCR, all other monocots produce pFCC-2	Spinacia oleracea

Two forms of primary fluorescent chlorophyll catabolite, pFCC, are found in plants, the slightly more polar pFCC-1 or the less polar pFCC-2. A third form, pFCC-3 is found only in basal pteridophytes and in some gymnosperms, it seems to be produced by an ancestral type of RCCR. RCCR-1 appears to have evolved independently in some unrelated lineages. It has a restricted phylogenetic distribution and most likely represents recent derivations from RCCR-2. The situation within monocots appears to be quite clear cut. All the grasses and Carex tested are characterized by type 1 of RCCR, all other monocots produce pFCC-2	Ginkgo biloba
