Fig. 6. Branchial hsp90
(A) and hsp90ß (B) mRNA
levels for northern (NH, hatched bars) and southern (GA, grey bars) killifish
exposed to heat shock. Control (C) samples were taken prior to
experimentation, and handling controls (CH) were treated identically to the
heat shock groups but exposed only to the acclimation temperature of 20°C.
All mRNA expression data is normalized to the control gene
EF-1
(values are mean ± s.e.m.; N=6).
Different letters indicates significant differences between treatments but
within a population, and an asterisk indicates a significant difference
between northern and southern fish within a treatment.
