Abstract: The present invention concerns methods for controlling fungus infestation via dsRNA mediated gene silencing, whereby the intact fungus cell(s) are contacted with a double-stranded RNA from outside the fungal cell(s) and whereby the double-stranded RNA is taken up by the intact fungal cell(s). In one particular embodiment, the methods of the invention are used to alleviate plants from fungus pests. Alternatively, the methods are used for treating and/or preventing fungal infestation on a substrate or a subject in need of such treatment and/or prevention. Suitable fungal target genes and fragments thereof, dsRNA constructs, recombinant constructs and compositions are disclosed.

Abstract: There is provided a method of identifying DNA responsible for conferring a particular phenotype in a cell which method comprises a) constructing a cDNA or genomic library of the DNA of the cell in a suitable vector in an orientation relative to a promoter(s) capable of initiating transcription of the cDNA or DNA to double stranded (ds) RNA upon binding of an appropriate transcription factor to the promoter(s), b) introducing said library into one or more of the cells comprising the transcription factor, and c) identifying and isolating a particular phenotype of the cell comprising the library and identifying the DNA or cDNA fragment from the library responsible for conferring the phenotype.
