ABSTRACT
During 2016–2017 surveys, carried out for phytoplasma diseases in ornamental plants in
Chaharmahal and Bakhtiari provinces, Iran, found symptoms of virescence, phyllody, reduced
size of leaves and flowers in columbine (Aquilegia vulgaris). Total DNAs extracted
from symptomatic and symptomless plants were tested for the presence of phytoplasma
using P1/P7 and R16F2n/R16R2 primers in direct and nested PCR producing amplicons
of about 1.8 and 1.2 kb, respectively, from all symptomatic A. vulgaris plants, but not from
symptomless ones. The consensus sequence of the detected phytoplasma named Aquilegia
phyllody (APh) was 100% identical with strains clustering to phytoplasmas enclosed in the
16SrI group as also confirmed by phylogenetic analyses. Both real and virtual restriction
fragment length polymorphism analysis of R16F2n/R16R2 amplicons showed profiles that
were identical to each other and indicated the affiliation of the APh phytoplasma to the
16SrI-R subgroup. This is the first report of a 16SrI-R phytoplasma associated with this
A. vulgaris phyllody disease.
