Pale yellow green7-1 (pyg7-1) is a photosystem I (PSI)-deficient Arabidopsis (Arabidopsis thaliana) mutant. PSI subunits are synthesized in the mutant, but do not assemble into a stable complex. In contrast, light-harvesting antenna proteins of both photosystems accumulate in the mutant. Deletion of Pyg7 results in severely reduced growth rates, alterations in leaf coloration, and plastid ultrastructure. Pyg7 was isolated by map-based cloning and encodes a tetratrico peptide repeat protein with… CONTINUE READING
