Abstract
Aster yellows group phytoplasmas were reclassified by analysis of the 16S rRNA gene sequence, their phylogeny and the presence of interoperon heterogeneity. Nine phytoplasmas were classified into subgroups 16SrI-B and 16SrI-D using the 16S rRNA gene sequence. Then, based on the presence of interoperon heterogeneity, subgroup 16SrI-B phytoplasmas were differentiated into three subunits as 16SrI-B(a): mulberry dwarf, sumac witches’ broom and porcelain vine witches’ broom; 16SrI-B(b): angustata ash witches’ broom and Japanese spurge yellows; and 16SrI-B(c): onion yellow dwarf, water dropwort witches’ broom and hare’s ear yellow dwarf phytoplasma.
