dc.description.abstract
FLOWERING LOCUS C (FLC) has a major regulatory role in the timing of flowering in Arabidopsis thaliana (L.) Heynh. and has more recently been shown to influence germination. Here, we investigated the conditions under which FLC influences germination, and demonstrated that its effect depends on the level of primary and secondary dormancy and the temperature of seed imbibition. We tested the germination response of genotypes with different degrees of FLC activity over the course of after-ripening and after secondary dormancy induction by hot stratification. Genotypes with high FLC-activity showed higher germination; this response was greatest when seeds exhibited primary dormancy or were induced into secondary dormancy by hot stratification. In this study, which used less dormant seeds, the effect of FLC was more evident at 22 C, the less permissive germination temperature, than at 10 C, in contrast to prior published results that used more dormant seeds. Thus, because effects of FLC variation depend on dormancy, and because the range of temperature that permits germination also depends on dormancy, the temperature at which FLC affects germination can also vary with dormancy. Finally, we document that the effect of FLC can depend on FRIGIDA and that FRIGIDA itself appears to influence germination. Thus, pleiotropy between germination
