The Genetic Basis of Thermal Reaction Norm Evolution in Lab and Natural Phage Populations
Figure 5
Growth Rates of Phage Isolated from Nature at High Temperatures
(A) Phylogenetic relationships of G4-like phages recently isolated from environmental samples, modified from [24]. The genotypes of two pairs of sister taxa that differ at a locus (gene H: A47V) determined to have a large effect on reaction norm shape are indicated with blue (alanine) and red (valine). (B and C) Thermal reaction norms of the two phage pairs. Data are means ± s.e.m. determined from four or five replicate measures at each temperature.
