The association of phytoplasma was investigated in symptomatic tomato (Solanum lycopersicum L.), eggplant (Solanum melongen L.), mallow (Malva spp.) and Bermuda grass (Cynodon dactylon L.) plants exhibiting witches’ broom and white leaf diseases, respectively. Total DNA was extracted from tomato (n=3), eggplant (n=2), mallow (n=2) and Bermuda grass (n=8) samples. Direct polymerase chain reaction (PCR) was performed using P1/P7 primer set, then PCR products were sequenced. Sequences obtained from tomato, eggplant and mallow shared 99% maximum nucleotide identity with phytoplasma belonging to subgroup 16SrII-D, and resulted therefore ‘Candidatus Phytoplasma australasia’-related. Sequences obtained from Bermuda grass showed 100% maximum nucleotide identity to 16SrXIV-A subgroup and were ‘Ca. P. cynodontis’-related. The study presents the first molecular confirmation and sequence data of presence of ‘Ca. P. australasia’ and ‘Ca. P. cynodontis’ in Iraq.
