Cloned(Commentary)

Cloned (Comment) Organism
fusion of the region encoding the putative transit peptide of NOL to the green fluorescent protein (GFP) gene and introduced into the epidermal cells of Allium cepa by particle bombardment Oryza sativa

Protein Variants

Protein Variants Comment Organism
additional information nyc1 mutant, shows the stay-green phenotype. Nol mutant (lines G079-11B, C130-10H and G087-9H) shows a stay-green phenotype very similar to that of the nyc1 mutant, i.e. the degradation of chlorophyll b is severely inhibited and light-harvesting complex II is selectively retained during senescence, resulting in the retention of thylakoid grana even at a late stage of senescence. The nyc1 nol double mutant does not show prominent enhancement of inhibition of chlorophyll degradation Oryza sativa

Localization

Localization Comment Organism GeneOntology No. Textmining
plastid NOL is localized on the stromal side of the thylakoid membrane despite the lack of a transmembrane domain. NOL and NYC1 interact physically in vitro, NOL and NYC1 are co-localized in the thylakoid membrane and act in the form of a complex as a chlorophyll b reductase Oryza sativa 9536
