Association of 'Candidatus Liberibacter solanacearum' with Zebra Chip Disease of Potato Established by Graft and Psyllid Transmission, Electron Microscopy, and PCR.
A new disease of potatoes, tentatively named zebra chip (ZC) because of the intermittent dark and light symptom pattern in affected tubers which is enhanced by frying, was first found in Mexico inExpand

Molecular characterization of DNA encoding 16S-23S rRNA intergenic spacer regions and 16S rRNA of pectolytic Erwinia species.
Sequences of 16S rDNAs and the intergenic spacer (IGS) regions between the 16S and 23S rDNA of bacterial strains from genus Erwinia were determined. Comparison of 16S rDNA sequences from differentExpand
