(A) and (B) Representation of the –log(10)-transformed p-values of the simple single locus association tests of each of the 119 sites that were included in the analysis. The black horizontal line corresponds to a significance threshold of p=0.05. The black dots represent polymorphic sites that associate with p>0.05, the red dots those with p<0.05. The green dots represent sites with p<0.05 that were chosen for detailed experimental analysis as shown Figure 4A. The FLM genomic gene model is as introduced in Figure 1. Each graph represents the analysis of the indicated expression trait. (A) shows all comparisons with relative expression values and (B) shows all comparisons of relative changes of transcript levels between FLM-β and FLM-δ in response to changes in temperature (15°C to 23°C) or ratios between the transcript levels (FLM-δ/FLM-β) at 15°C and 23°C as a readout for the relative abundance of the two splice forms with hypothesized antagonistic functions. Quantitative values are summarized in Supplementary file 5.
