Identification of catabolites of chlorophyll-porphyrin in senescent rape cotyledons

Developing shoots of rape seedlings (Brassica napus L.) were excised and fed with 4-[14C]5-aminolevulinic acid to label the pyrroles in chlorophyll (Chl) synthesized during the final phase of expansion and greening of the cotyledons. About 80% of 14C taken up into the cotyledons was incorporated int...
