Knock-out of the genes coding for the Rieske protein and the ATP-synthase [delta]-subunit of Arabidopsis. Effects on photosynthesis, thylakoid protein composition, and nuclear chloroplast gene expression1[w]

In Arabidopsis, the nuclear genes PetC and AtpD code for the Rieske protein of the cytochrome b^sub 6^/f(cyt b^sub 6^/f) complex and the [delta]-subunit of the chloroplast ATP synthase (cpATPase), respectively. Knock-out alleles for each of these loci have been identified. Greenhouse-grown petc-2 and atpd-1 mutants are seedling lethal, whereas heterotrophically propagated plants display a high-chlorophyll (Chl)-fluorescence phenotype, indicating that the products of PetC and AtpD are essential for photosynthesis. Additional effects of the mutations in axenic culture include altered leaf ...
