What if next Valentine's Day, you could time the flowers you bought to blossom just as your spouse walked in the door?

The patent (US 6,693,228) covers the Flowering Locus C1 (FLC1) gene, which contains a MADS box domain, and a method by which it is connected to an expressible promoter. The FLC locus is one of two that controls flowering in Arabidopsis; the other is FRIGIDA. When expressed, FLC delays flowering.
