First report of Little cherry closterovirus-1 in Poland
So far 3 closteroviruses associated with little cherry disease have been described (Little cherry closterovirus-1 [LChV-1], LChV-2, LChV-3 – EU Annexes). In Poland, during the 2003 growing season, virus-like symptoms were observed on sour cherry trees (Prunus cerasus) growing in commercial orchards and in a germplasm collection of Prunus. Affected trees showed irregular, chlorotic mottling, distortion and premature leaf fall. Leaf samples were collected and tested (DAS-ELISA, RT-PCR) for several viruses affecting cherry. Results revealed the presence of Cherry virus A on 15 trees and of LChV-1 on 2 trees. These viruses are reported for the first time in Poland. Some trees were also affected by Prunus necrotic ringspot ilarvirus and Prune dwarf ilarvirus.
