Summary

We have examined the late-flowering behavior of two ecotypes of Arabidopsis thaliana, Sf-2 and Le-0. The late-flowering trait segregates as a single dominant gene in crosses with the early-flowering Columbia ecotype. This gene, which we refer to as FLA, is located at one end of chromosome 4 between RFLP markers 506 and 3843 and is thus distinct from previously mapped genes that affect flowering time. The extreme delay in flowering time caused by the FLA gene can be overcome by vernalization in both the ecotypes in which it occurs naturally and in the Columbia ecotype into which this gene has been introgressed.
