| genetic structure of graphocephala atropunctata (hemiptera: cicadellidae) populations across its natural range in california reveals isolation by distance. | the genetic structure of 23 populations of graphocephala atropunctata (signoret) (hemiptera: cicadellidae: cicadellinae), a vector of the plant pathogenic bacterium xylellafastidiosa wells et al., was investigated using ribosomal 28s and mitochondrial cytochrome c oxidase i gene sequences. the 28s sequences were identical across all g. atropunctata specimens and populations, but 16 mitochondrial haplotypes were detected and significant interpopulation differences were found in the distribution o ... | 2011 | 21404869 |
