High genetic variation in a small population of Cherry leaf roll virus in Betula sp. of montane origin in Corsica
Summary Cherry leaf roll virus ( CLRV ) infection is common in Betula pendula and B. pubescens in Middle and North Europe, easily observable by chlorotic leaf vein banding, mottling and leaf roll, partially adherent with progressive loss of vitality or death of twigs and branches. In Fennoscandia, a...

| Summary: | Summary Cherry leaf roll virus ( CLRV ) infection is common in Betula pendula and B. pubescens in Middle and North Europe, easily observable by chlorotic leaf vein banding, mottling and leaf roll, partially adherent with progressive loss of vitality or death of twigs and branches. In Fennoscandia, a severe viral epidemic in various birch species in forest stands, public greens and roadsides is associated with CLRV . In Corsica, CLRV ‐typical symptoms were observed on birch trees ( Betula sp.) in a montane stand (1470 m) at Col de Vergio. CLRV was detected by RT ‐nested PCR in all leaf samples from 11 randomly selected birch trees exhibiting characteristic symptoms. Along with the fact that this is the first report of CLRV in Betula sp. of both montane and Mediterranean origins, remarkably high genetic variation and a new distinct phylogenetic cluster are comprised by a small randomly sampled CLRV population that has evolved in one of the few scattered birch stands in Corsica. |
