Applied Virology
What can Plant viruses can be transmitted by?
Applied Virology
What was one of the first methods to get rid of a plant virus -> get a virus free plant?
By meristem culture.
Applied Virology
What name can the virus particle be given based on its molecular composition? A protein? A Nucleic acid?
It is a nucleoprotein.
Applied Virology
Which parts of a virus are critical end can be sufficient for infection?
Only the genome!
Applied Virology
How does the TMV move through the infected plant?
Applied Virology
What makes a virus "well adapted"?
That it deos not show any symptoms.
Applied Virology
What is the most important route of plant virus transmission?
Insect transmission
Applied Virology
What means "stylet borne", when it comes to plant viruses? Why is this form of transmission "non-persistent"?
It means, that the virus is carried over by the stylets, the chewing tools of the insect. Because this contamination is very superficial and the virus does not use the insect as a host, the contamination is rather transient and is not "persistent"
Applied Virology
What is the "acquisition feed"?
(insect-plant relation)
The aquisition feed is the process of an uncontaminated insect feeding on an infected plant (aquires the virus)
Applied Virology

It enters the salivary glands and is transmitted via the saliva.
Applied Virology
What are 4 of the tools that are used in a regulatory manner to control plant virus diseases?
Applied Virology
What is the basis of the Dot blot?
The dot blot is basically a hybridization technique that uses radiolabeled probes to bind the complementary ssDNA (melted before)-> e.g. potentially present viral DNA in plant sap.
