CC   -!- FUNCTION: Truncated inactive FRIGIDA-like 1 protein.
CC       {ECO:0000269|PubMed:17056759}.
CC   -!- MISCELLANEOUS: In cv. Columbia and cv. Landsberg erecta, either FRL1 or
CC       FRL2, but not both, is functional and required for FRI-mediated up-
CC       regulation of FLC (PubMed:17056759). {ECO:0000305|PubMed:17056759}.
CC   -!- SIMILARITY: Belongs to the Frigida family. {ECO:0000305}.
CC   -!- CAUTION: In cv. Columbia, FRL1 (AC Q9FFF1) is full-length and
CC       functional. {ECO:0000305}.
