Abstract
The association of phytoplasma was investigated in sand olive [Dodonaea viscosa ssp. Angustifolia (L. f.) J.G. West], cowpea [Vigna unguiclata (L.)] Wap and alfalfa (Medicago sativa L.) plants exhibiting witches broom, fasciation and little leaf symptoms, respectively. Sequence analysis of ~1.7 kb DNA fragments amplified by P1/P7 primer set confirmed the association of 'Candidatus Phytoplasma aurantifolia' within symptomatic alfalfa, while 'Ca. Phytoplasma cynodontis' was associated within cowpea and sand olive.
