| genetic diversity of european phytoplasmas of the 16srv taxonomic group and proposal of 'candidatus phytoplasma rubi' | in addition to the grapevine flavescence dorée phytoplasmas, other members of the taxonomic group 16srv infect grapevine, alders, clematis and rubus in europe. in order to investigate which phytoplasmas constitute discrete, species-level taxa, several isolates were analysed comparing their 16s rrna gene sequence and a set of five house-keeping genes. whereas 16s rrna gene sequence identities were above 97.5 %, which is the proposed threshold to distinguish two 'candidatus phytoplasma' species, p ... | 2010 | 20889771 |
