Inheritance of a Chlorophyll Deficiency in Hazelnut
A chlorophyll deficiency expressed as yellowing of leaves was observed in hazelnut (Corylus avellana L.) progenies. Segregation ratios approximated 3 green : 1 yellow, indicating control by a single recessive gene designated chlorophyll deficient #1, for which the symbol c, is proposed. ‘Barcelona’, ‘Butler’, ‘Compton’, ‘Lansing’, Willamette’, and the ornamental selection ‘Redleaf #3’ are heter...
متن کاملGenetic Studies of Induced Mutants in Melilotus alba. II. Inheritance and Complementation of Chlorophyll-deficient Mutants
Six ethyl methanesulfonate-induced mutants of Melilotus alba Desr. were studied. Five of the mutants behaved as monogenic recessives. In the sixth mutant, two independent recessive alleles were responsible for the observed phenotype. Of these two genes, one had a phenotypic effect similar to the five single-gene mutants. The other (the veined gene) caused a chlorophyll deficiency in which the l...
متن کاملChlorophyll 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 کاملChlorophyll a oxygenase (CAO) is involved in chlorophyll b formation from chlorophyll a.
Chlorophyll b is an ubiquitous accessory pigment in land plants, green algae, and prochlorophytes. Its biosynthesis plays a key role in the adaptation to various light environments. We isolated six chlorophyll b-less mutants by insertional mutagenesis by using the nitrate reductase or argininosuccinate lyase genes as tags and examined the rearrangement of mutant genomes. We found that an overla...
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...
