Inactive FRIGIDA-like 2 protein. Expressed at low levels throughout the plant, with slightly higher expression in developing seeds and the highest expression in pollen. No effect on flowering time, due to a partial redundancy with FRL1. Frl1 and frl2 double mutants flower earlier than frl1 single mutant. In cv. Columbia and cv. Landsberg erecta, either FRL1 or FRL2, but not both, is functional and required for FRI-mediated up-regulation of FLC (PubMed:17056759). Belongs to the Frigida family. The sequence displayed is a non-functional allele found in cv. Columbia. The protein in cv. Landsberg erecta (AC A0SWL0) only differ by two residues in positions 132 and 401 (Pro to Ala and Gln to Leu changes, respectively); these variations leading to activate the protein in cv. Landsberg erecta.
