Prunus species plants can be infected by eight ‘Candidatus Phytoplasma’ (‘Ca. P.’) species classified to eight distinctive taxonomic groups: ‘Ca. P. prunorum’ (16SrX-B), ‘Ca. P. mali’ (16SrX-A), ‘Ca. P. pyri’ (16SrX-C), ‘Ca. P. asteris’ (16SrI), ‘Ca. P. aurantifolia’ (16SrII), ‘Ca. P. ziziphi’ (16SrV), ‘Ca. P. fraxini’ (16SrVII), ‘Ca. P. phoenicium’ (16SrIX) and two potentially new species: ‘Ca. P. pruni’ (16SrIII) and ‘Ca. P. solani’ (16SrXII). These agents occur incidentally in orchards and their impact on stone fruit production is lower than ‘Candidatus Phytoplasma prunorum’. Hosts, geographic distribution, symptoms and insect vectors of these ‘Ca. P.’ species, methods of their identification, and control management are reviewed.
