pox virus strain M

The genetic diversity of plum pox virus strain M (PPV-M) was assessed by analyzing 28 isolates collected in 8 European
countries. Two genomic fragments spanning the (Cter)P3-6K1-(Nter)CI coding region as well as the full coat protein coding
region were sequenced directly from PCR products. Phylogenetic analysis showed that the geographical origin of the collected
isolates was clearly associated with two different PPV-M clades. Moreover, the pattern of substitutions in the CP gene shed light
on the evolutionary relationships between PPV-M and the recombinant strains PPV-Rec and PPV-T.

The genetic diversity of three temperate fruit tree phytoplasmas ‘Candidatus Phytoplasma prunorum’, ‘Ca. P. mali’ and ‘Ca. P.
pyri’ has been established by multilocus sequence analysis. Among the four genetic loci used, the genes imp and aceF
distinguished 30 and 24 genotypes, respectively, and showed the highest variability. Percentage of substitution for imp ranged
from 50 to 68 % according to species. Percentage of substitution varied between 9 and 12 % for aceF, whereas it was between 5
and 6 % for pnp and secY. In the case of ‘Ca P. prunorum’ the three most prevalent aceF genotypes were detected in both plants
and insect vectors, confirming that the prevalent isolates are propagated by insects. The four isolates known to be hypo-virulent
had the same...

Des pucerons ailés vivants, en activité au niveau de la végétation d’une parcelle de melons contaminée à 100 du p. 100 par le
virus de la mosaïque du concombre (CMV), ont été capturés à l’aide de pièges à succion et placés rapidement sur des melons
