Abstract excerpt
Application of norflurazon (NF) damages plastids, induces photobleaching and represses expression of the nuclear LHCB1.2 gene encoding a light-harvesting protein. In genomes uncoupled (gun) mutants, LHCB1.2 expression is maintained in the presence of NF. The mutants gun2, gun4 and gun5 exhibit perturbations in tetrapyrrole biosynthesis, but gun1 is defective in organellar gene expression (OGE). How gun mutations...
