Chlorophyll Degradation.
Although the loss of green color in senescent leaves and ripening fruits is a spectacular natural phenomenon, research on chlorophyll breakdown has been largely neglected until recently. This review summarizes knowledge about the fate of chlorophyll in degreening tissues that has been gained during the past few years. Structures of end- and intermediary products of degradation as well as the bi...
متن کاملDuplicate chlorophyll-deficient loci in soybean.
Three lethal-yellow mutants have been identified in soybean (Glycine max (L.) Merr.), and assigned genetic type collection numbers T218H, T225H, and T362H. Previous genetic evaluation of T362H indicated allelism with T218H and T225H and duplicate-factor inheritance. Our objectives were to confirm the inheritance and allelism of T218H and T225H and to molecularly map the locus and (or) loci cond...
متن کاملSimulating Concerted Evolution
Teshima and Innan, in [1], describes simulation results for duplicated genes under concerted evolution. Their simulation method evolves a pair of initially identical genes; mutations can accumulate in the two genes—under an infinite sites mutation model—causing divergence between the genes, and gene conversions can occur between the two genes, reducing the divergence again. Their method, howeve...
متن کاملA new chlorophyll degradation pathway.
Chlorophyll degradation is vital during leaf senescence and fruit ripening, as it allows for recycling of nitrogen and other nutrients and for protection from buildup of phototoxic chlorophyll intermediates (Hörtensteiner, 2006). The first steps in chlorophyll breakdown are the removal of the phytol tail (dephytylation) and the central Mg atom. It has been thought that dephytylation typically o...
متن کاملChlorophyll b to chlorophyll a conversion precedes chlorophyll degradation in Hordeum vulgare L.
This study reveals by in vivo deuterium labeling that in higher plants chlorophyll (Chl) b is converted to Chl a before degradation. For this purpose, de-greening of excised green primary leaves of barley (Hordeum vulgare) was induced by permanent darkness in the presence of heavy water (80 atom % (2)H). The resulting Chl a catabolite in the plant extract was subjected to chemical degradation b...
