Protein Variants

Protein Variants Comment Organism
additional information the non-yellow coloring, nyc1, recessive mutant is a rice stay-green phenotype mutant due to a defect in chlorophyl degradation, in which chlorophyll degradation during senescence is impaired, the mutant NYC1 does not show chlorophyll b reductase activity, but NOL, i.e. NYC1-like, a protein closely related to NYC1 in rice, shows chlorophyll b reductase activity in vitro, phenotype, overview, a double mutant from a cross between nyc1-2 and a chlorophyll b-deficient mutant cao-2 does not show the stay-green senescence phenotype, overview Oryza sativa
