Samples from apricot trees showing typical chlorotic leafroll symptoms were collected in June/July 2010 in Serbia and Italy. Phytoplasma detection was achieved by polymerase chain reaction and restriction fragment length polymorphism analyses on amplicons obtained after nested-PCR assays. 16SrX-B, 16SrXII and 16SrI phytoplasmas were identified in single or mixed infection in the Serbian samples, while 16SrX-B,16SrXII and 16SrIX-C were detected in single or mixed infection in the Italian samples. This is the first report of the presence in symptomatic apricot of different phytoplasmas from ESFY, in particular the 16SrIX-C phytoplasma is reported for the fist time in this species. Work to verify the epidemic relevance of these phytoplasmas in the apricot chlorotic leafroll disease is in progress.

Abstract
Samples from apricot trees showing typical chlorotic leafroll symptoms were collected in June/July 2010 in Serbia and Italy. Phytoplasma detection was achieved by polymerase chain reaction and restriction fragment length polymorphism analyses on amplicons obtained after nested-PCR assays. 16SrX-B, 16SrXII and 16SrI phytoplasmas were identified in single or mixed infection in the Serbian samples, while 16SrX-B,16SrXII and 16SrIX-C were detected in single or mixed infection in the Italian samples. This is the first report of the presence in symptomatic apricot of different phytoplasmas from ESFY, in particular the 16SrIX-C phytoplasma is reported for the fist time in this species. Work to verify the epidemic relevance of these phytoplasmas in the apricot chlorotic leafroll disease is in progress.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
