Figure 3

Relative expression levels of FRI and FLC in Arabidopsis accessions and F 1 hybrids grouped by their FRI allele. (a and b) 137 Arabidopsis accessions were grown in long days under greenhouse conditions, sampled after four weeks and expression levels of FLC and FRI were quantified from northern hybridizations [38]. Letters in each bar indicate the significance groups as determined by a Tukey HSD test. The number in each bar indicates the number of accessions in each group. (c and d) Positions with SNPs specific to Ler-1 or Col-0 were targeted using pyrosequencing in genomic DNA (c) or in cDNA (d) of F1 hybrids. Leaf material for hybrids involving Bor-4, Bur-0, Knox-10 or Sha was collected at the time of bolting from plants growing under 12-hour photoperiods in an environmental chamber. Leaf material from hybrids involving Col-0 was collected from 10 day-old seedlings grown in the greenhouse in long days. Error bars indicate the standard error of the mean.
