    G×G×E effect on phenotype expression in the unicellular slime mould Physarum polycephalum

    No full text
    We developed a genetic panel of the unicellular slime mould, Physarum polycephalum containing strains differing in mitochondrial and nuclear DNA haplotypes. The panel included two strains harbouring a selfishly replicating mitochondrial-fusion (mF) plasmid that could affect phenotype expression. We assayed movement and growth rate differences among the strains across two temperature regimes: 24° and 28°C. The dataset contains raw data from growth rate and movement assays.</p

    Diet and mitonuclear haplotype interactions affect growth rate in a slime mould

    No full text
    Using a panel of six slime mould mitonuclear strains, we show that the growth rate of P. polycephalum is generally higher on diets containing more carbohydrates than protein. Three-way interactions between mitochondrial, nuclear haplotypes and dietary P:C ratios affected the strains' surface area of growth but not biomass. And, the strains did not increase their surface area and biomass when they had access to all diets on the buffet menu, compared to a set menu where they had access to one type of diet. </p
