The identification of genes contributing to speciation has the potential to provide important insights into the mechanisms of evolution. One of the most interesting unresolved puzzles is the relationship between intraspecific variability in morphological traits and their interspecific divergence. Intraspecific polymorphisms without major detrimental(More)
The properties of alleles at quantitative trait loci (QTLs) contributing to variation in lifespan should be described to determine the mechanisms of evolution of life length and to predict its future changes. Previously, we and others conducted genome-wide screens for QTLs that segregate among one panel of recombinant inbred lines (RILs) using a dense(More)
We describe a novel fungal expression system which utilizes the Quorn® myco-protein fungus Fusarium graminearum A 3/5. A transformation system was developed for F. graminearum and was used to introduce the coding and regulatory regions of a trypsin gene from Fusarium oxysporum. The protein was efficiently expressed, processed and secreted by the recombinant(More)
Knowledge of genes responsible for aging and death is a prerequisite for determining the relative contributions of the different evolutionary factors responsible for the limited duration of life. Polymorphism of these genes probably accounts for the variation in lifespan. Previously, quantitative trait loci (QTLs) controlling this variation were mapped with(More)
