Relationship between olpidium virulentus and LBVD - Coggle Diagram
Relationship between olpidium virulentus and LBVD
Lettuce- virus relationships
LBVaV and MLBVV natural host range limited
The role of LBVaV in LBVD is unclear
Olpidium virulentus
more than one exit tube for sporangia, could be classified under pleotrachelus.
O. virulentus is the vector of LBVD viruses.
infect lettuce and tomato
viruses: tobacco stunt virus and MLBVV
homothallic, noncrucifer infecting
different subclades divded by region
1st subclade- europe and japan
2nd subclade- japan
australian and japan isolated are found in both subclades
Olphidium- plant associations
simple life cycle, 3-4 days to mature, 3-4 weeks to produce sporangia
along with lettuce, can infect melon, water melon and tomato
invade fine roots
virus associations
virus attaches to zoospores and resting spores
the mechanism of virus release into plants is unknown
viruses may impact fungal ecology and evolution
disease management strategies
development in resistant plants
methyl bromide to control resting spores
detect zoospores that are carrying disease
study these diseases in weeds
prevention of disease spread and introduction
commerical lettuce seedling nurseries
