The most important genes of Arabidopsis autonomous and gibberellin pathways as well as some other floral regulators are presented. The biological function of the genes is indicated, and floral activators and repressors are marked by + and - marks, respectively. Moreover, the presence or absence of homologous sequence in Fragaria sequence databases and E-value of BLASTx comparison against Arabidopsis are indicated. Sequences found in our libraries are named BAR and VES for everbearing genotype 'Baron Solemacher' and short-day genotype, respectively. Other ESTs and EST contigs are found from Genome Database for Rosaceae http://www.bioinfo.wsu.edu/gdr/. More complete list is available in Additional file 2.
