Abstract
A FLORICOULA/LEAFY (FLO/LFY) homolog CnFL gene was isolated from the flower bud of a short-day Chrysanthemum nankingense plant during the flowering induction period. The sequence of CnFL contained a 1236Â bp open reading frame that encoded a putative protein of 412 amino acids, which shared 68.67% homology with FLO and 60.23% homology with LFY. The spatial expression patterns of CnFL were analyzed using quantitative real-time PCR in different tissues and the apical meristem during short-day flowering induction. The results indicated that CnFL was highly expressed in the flower buds while its expression was also detected in the stems, young leaves, and vegetative apical meristem. During the period of flowering induction, CnFL expression increased remarkably and reached its highest levels after 15 days of induction. The expression of CnFL in the apical shoot after short-day flowering induction indicates that CnFL regulation is controlled primarily by photoperiodicity.
