Aphid transmissibility of different European beet polerovirus isolates Inra
Kozlowska-Makulska, A.; Beuve, M.; Syller, J.; Szyndel, M.S.; Lemaire, O.; Bouzoubaa, S.; Herrbach, E..
Different field isolates of the ‘beet poleroviruses’Beet mild yellowing virus (BMYV) and Beetchlorosis virus (BChV) (genus Polerovirus, familyLuteoviridae) collected in France and Poland wereevaluated for transmissibility from and to sugar beetplants by different aphid species. In general, bothBMYV and BChV were efficiently transmitted by Myzus persicae and by a French clone of Macrosiphumeuphorbiae. In contrast, transmissibility of the twopoleroviruses by an English clone of M. euphorbiaewas evidently weaker, although the aphid samplescontained the virus as demonstrated by RT-PCR. Noneof the BMYV or BChV isolates was transmitted byAphis fabae or Myzus ascalonicus. In attempting tocorrelate biological properties with molecular variations,the RT proteins...

Biological properties and molecular characterization of beet chlorosis virus (BChV) Inra
Hauser, S.; Stevens, M.; Beuve, M.; Lemaire, O..
 Two distinct viruses belonging to the Polerovirus genus, in the family Luteoviridae, have been described as being able to induce mild yellowing on sugar beet: Beet mild yellowing virus (BMYV) and more recently, beet chlorosis virus (BChV). We have analysed biological properties and molecular organisation of two strains of BChV, one collected in England and the second from California. The biological data suggested that BChV displayed a narrower host range compared to BMYV and Beet western yellows virus lettuce isolate (BWYV). The complete genomic RNA sequence of the American isolate BChV-California and the European isolate BChV-2a showed a genetic organisation and expression typical of other Polerovirus members including 6 open reading frames (ORFs)....
