The Willamette Valley, west of the Cascade mountain range in the state of Oregon, is home to a growing number of vineyards. This rather recent, booming industry of the region has become an important component of the economy of the state’s agriculture since the late 1960’s, contributing more than $1.56...
Papain-like leader proteases are found in diverse families of human, animal, plant, and fungal positive-strand RNA viruses. In addition to autocatalytic processing, these proteases play a variety of roles in the virus life cycle. In particular, the leader protease (L-Pro) of a prototype member of the Closterovirus genus, Beet yellows...
A pheromone lure baited with the sex pheromone of grape mealybug is the most reliable way to confirm the presence or absence of this important vector of grapevine leafroll-associated viruses.

Virus contamination in a potato breeding program can seriously
disrupt the variety development process. Experiments were conducted
from 1989 through 1993 to: evaluate the extent to which Potato
Leafroll Virus (PLRV) and Potato Virus Y (PVY) can invade a breeding
program, determine viral spread within hills and within individual
tubers,...
Potato leafroll virus (PLRV) causes yield and quality losses in
potato. PLRV is identified by plant symptoms and serological tests
such as an enzyme-linked immunosorbent assay (ELISA). A similar
serological test, direct tissue blotting assay (DTBA), was used to
detect and monitor PLRV movement in field-inoculated Russet Burbank
plants and...
