title: DNA sequence of the ribosomal protein genes rp12 and rps19 from a plant-pathogenic mycoplasma-like organism.
abstract: A segment of a ribosomal protein operon from a plant-pathogenic mycoplasma-like organism (MLO) was cloned and sequenced, to provide supplemental molecular data pertinent to the question of MLO phylogeny. Comparisons of the deduced amino acid sequences indicate an ancient divergence of the MLOs from the animal-pathogenic mycoplasmas. Furthermore, although both the plant and animal pathogens have A-T rich genomes, a fundamental difference was apparent in their usage of the UGA codon.
