Abstract
The present invention relates to an isolated strain of DNA mycovirus or a degenerate strain thereof, an isolated hypovirulent fungal strain or part thereof, and the use of the isolated strain of DNA mycovirus or hypovirulent fungal strain or part thereof as a biological control agent. Processes and compositions for the biological control of phytopathogenic microorganisms, particularly fungi, using the DNA mycovirus and hypovirulent fungal strain are also provided.
Claims17
An isolated DNA mycovirus or degenerate strain thereof encoding at least one polypeptide comprising at least 70% sequence identity to a polypeptide selected from the group consisting of SEQ ID NO:
- 2, SEQ ID NO:
- 4 and SEQ ID NO:
- 6.
An isolated polypeptide comprising at least 70% sequence identity to an amino acid sequence selected from the group consisting of SEQ ID NO:
- 2, SEQ ID NO:
- 4 and SEQ ID NO:
- 6.
An isolated nucleic acid sequence comprising at least 70% sequence identity to SEQ ID NO:
- 1.
An isolated DNA mycovirus comprising SEQ ID NO:
- 1, or a degenerate strain thereof.
A method of Botrytis spp. biocontrol comprising contacting at least one Botrytis spp. with an isolated DNA mycovirus, or degenerate strain thereof.
A method of controlling at least one phytopathogenic fungus comprising contacting the fungus with an isolated DNA mycovirus of claim 1 or claim 5, a vector of claim 6, an isolated host cell of claim 7 or claim 8, a composition of claim 9, or a combination thereof. The method of claim 10, 12 or 13 wherein the phytopathogenic fungus is a Botrytis spp., preferably Botrytis cinerea.
An isolated DNA mycovirus, or a degenerate strain thereof, for use in controlling Botrytis spp. fungi.
