Upsetting the balance of resource allocation
How do organisms allocate resources to different aspects of life and what are the consequences of differences in this allocation? To explore these questions at both genetic and phenotypic levels I generated a genetically heterogeneous population of the fungus Neurospora crassa which contains genes from 20 naturally isolated strains and performed selection experiments to bias resource allocation toward reproduction or growth. I used RADseq to genotype the parental lines, individuals from the heterogeneous population, and the evolved lines. I have also measured growth rate and spore production in these individuals in two conditions. Using this massive data set, I will determine whether biasing resource allocation toward growth or reproduction influences investment in the other and identify regions of the genome associated with the response to selection (population genomic comparisons between ancestral population and evolved lines). In addition to addressing important questions in life history evolution, this study represents a new approach for experimental study using Neurospora, which has previously been largely limited to studies of single strains and genetic mutants.
