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 (exp 2 growth rate.csv) and movement (exp 1 race track.csv) assays. Also included are the excel spreadsheet containing the mean phenotype values for the six mitonuclear strains across both temperatures (inter trait correlation.csv), R script file used for data analyses and a spreadsheet containing the list of gene sequences generated in the study.
