Construction and high-throughput phenotypic screening ofZymoseptoria tritici over-expression strains.

ABSTRACT: Targeted gene deletion has been instrumental in elucidating many aspects of Zymoseptoria tritici pathogenicity. Gene over-expression is a complementary approach that is amenable to rapid strain construction and high-throughput screening, which has not been exploited to analyze Z. tritici, largely due to a lack of available techniques. Here we exploit the Gateway® cloning technology for rapid construction of over-expression vectors and improved homologous integration efficiency of a Z. tritici Δku70 strain to build a pilot over-expression library encompassing 32 genes encoding putative DNA binding proteins, GTPases or kinases. We developed a protocol using a Rotor-HDA robot for rapid and reproducible cell pinning for high-throughput in vitro screening. This screen identified an over-express
