Symptoms of shoot dieback and leaf yellowing followed by leaf chlorosis were observed in naturally infected roses 'Frisco' and 'Suela', cultivated in a commercial greenhouse in Poland. The presence of phytoplasma was demonstrated in affected plants by nested polymerase chain reaction (PCR) with R16Fl/RO and Pl/P7 primer pairs in the first round followed by a second one with R16F2n/R2, fA/rA, Pc399/P1694, R16(I)Fl/Rl and Pl/fArev primer pairs. Restriction fragment length polymorphism (RFLP) analysis of PCR products (primed with primers R16F2n/R2) was done using enzymes AluI, MseI, RsaI and HpaII. Restriction profiles obtained with these enzymes were identical to those of reference strain AY1 belonging to aster yellows phytoplasma group, subgroup I-B (16SrI-B). Nested PCR products from roses 'Frisco' and 'Suela' were sequenced. Analysis of sequences confirmed that the phytoplasma infecting those roses could be classified to aster yellows phytoplasma group, subgroup B
