Differential regulation of genes transcribed by nucleus-encoded plastid RNA polymerase, and DNA amplification, within ribosome-deficient plastids in stable phenocopies of cereal albino mutants.

Abstract excerpt

We isolated stable albino plants of barley and maize by inhibiting plastid protein synthesis with streptomycin and propagating bleached seedlings in the absence of antibiotics in vitro. Albino plants are deficient in plastid translation products and plastid ribosomal RNAs, and are stable phenocopies of the barley albostrians and maize iojap mutants, which contain ribosome-free plastids. Once plastid ribosomes are...
