H. Fakhfakh et al., SEQUENCE POLYMORPHISM IN THE 3'-NTR AND T HE CP PROTEIN OF 3 TUNISIANISOLATES OF THE POTATO-VIRUS-Y, Agronomie, 15(9-10), 1995, pp. 569-579
In Tunisia, potato virus Y (PVY) causes yield losses, particularly on
pepper cultures. Sequence analysis from the 3'non-translated region (3
'-NTR) and from the coat protein coding region (CP) of 2 PVY isolates
from pepper and 1 from potato are in agreement with the biological cla
ssification. Potential RNA secondary structure analysis of the 3'-NTR
region revealed additional differences between isolates. Phylogenetic
analysis of these 3 sequences suggests that 1 isolate (PVY-P21) might
have emerged through a recombination process.
