Lagercrantz & Axelsson (2000): A family of CONSTANS LIKE genes (COLs) has recently been identified in Arabidopsis thaliana and other plant species. CONSTANS, the first isolated member, is a putative zinc finger transcription factor that promotes the induction of flowering in A. thaliana in long photoperiods.
