Cross-protection test with 'Candidatus Phytoplasma mali' 1/93 strain against closely and distantly related phytoplasma strains
Acta Phytopathologica et Entomologica Hungarica 48 (2), 207-218
Abstract: Putative inhibitory effect of `Candidatus Phytoplasma mali' 1/93 mild strain was tested under greenhouse conditions against the related ESFY and the distantly related STOL and AAY strains of `Candidatus Phytoplasma prunorum', `Candidatus Phytoplasma solani' and 'Candidatus Phytoplasma asteris', respectively, which are responsible for serious damages and yield losses in fruit orchards across Europe. A consequent decrease of the DNA amount of the virulent GSFY strain analysed by PCR and Real-Time PCR could be observed when the plants were preliminary immunised by 1/93 strain. The cross-protection phenomenon proved to be effective between closely related strains, but no inhibition occurred among distantly related strains due to preliminary infection. Our results support that immunization with a mild, antagonist strain can be of phytopathological relevance in phytoplasmal researches.
