Project description:Knockout mutants of polyketide synthase genes were generated (pks1, pks2, pks3, pks14, pks18, pks37) and compared to wild-type AX2 strain of Dictyostelium discoideum using Agilent custom microarrays. The Dictyostelium cells were harvested at eight developmental stages (Amoeboid, Intiation of starvation, loose aggregate, Streaming, Mound, Slug, early culminant, Fruiting body) and subjected to microarray based expression profiling.
