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

We developed a genetic panel of the unicellular slime mould, <em>Physarum polycephalum</em> 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.
