Summary
The timing of »owering is important for the reproductive success of plants. Here we describe the
identi«cation and characterization of a new MADS-box gene, FLOWERING LOCUS M (FLM), which is
involved in the transition from vegetative to reproductive development. FLM is similar in amino-acid
sequence to FLC, another MADS-box gene involved in »owering-time control. »m mutants are early
»owering in both inductive and non-inductive photoperiods, and »owering time is sensitive to FLM
dosage. FLM overexpression produces late-»owering plants. Thus FLM acts as an inhibitor of »owering.
