Genome-wide identification and expression analysis of SBP-box gene family reveal their involvement in hormone response and abiotic stresses in Chrysanthemum nankingense.

ABSTRACT: SQUAMOSA promoter-binding-protein (SBP)-box family proteins are a class of plant-specific transcription factors, and widely regulate the development of floral and leaf morphology in plant growth and involve in environment and hormone signal response. In this study, we isolated and identified 21 non-redundant SBP-box genes in Chrysanthemum nankingense with bioinformatics analysis. Sequence alignments of 21 CnSBP proteins discovered a highly conserved SBP domain including two zinc finger-like structures and a nuclear localization signal region. According to the amino acid sequence alignments, 67 SBP-box genes from Arabidopsis thaliana, rice, Artemisia annua and C. nankingense were clustered into eight groups, and the motif and gene structure a
