Summary The timing of flowering is important for the reproductive success of plants. Here we describe the identification 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 flowering‐time control. flm mutants are early flowering in both inductive and non‐inductive photoperiods, and flowering time is sensitive to FLM dosage. FLM overexpression produces late‐flowering plants. Thus FLM acts as an inhibitor of flowering. FLM is expressed in areas of cell division such as root and shoot apical regions and leaf primordia.
