SQUAMOSA promoter-binding protein(SBP)transcription factors are known tofunction in a number of processes in plants.Here,we have characterized twelve SBP-like(SPL)genes in the important ornamental species chrysanthemum(Chrysanthemummorifolium).A total of twelve distinct sequences were isolated and amplified based ontranscriptomic sequences.Phylogenetic analysis identified two pairs of orthologous proteinsfor Arabidopsis and chrysanthemum and two pairs of paralogous proteins in chrysanthemum.
