Abstract

The basic leucine zipper (bZIP) is a widely known transcription factors family in eukaryotes. In plants, the role of bZIP proteins are crucial in various biological functions such as plant growth and development, seed maturation, response to light signal and environmental stress. To date, bZIP protein family has been comprehensively identified in Arabidopsis, castor, rice, ramie, soybean and other plant species, however, the complete genome-wide investigation of Carthamus tinctorius-bZIP family still remains unexplained. Here, we identified 52 putative bZIP genes from Carthamus tinctorius using a draft genome assembly and further analyzed their evolutionary classification, physicochemical properties, Conserved domain analysis, functional differentiation and the investigation of expression level in different tissues. Based on the common bZIP domain, CtbZIP family were clustered into 12 subfamilies renamed as (A-J, S, X), of which the X is a unique subfamily to Carthamus tinctorius. A total of 20 conserved protein motifs were found in CtbZIP proteins. The expression profiling of CtbZIP genes deciphered their tissue-specific pattern. Furthermore, the changes in CtbZIP transcript abundance suggested that their transcription regulation could be highly influenced by light intensity and hormones. Collectively, this study highlights all functional and regulatory elements of bZIP transcription factors family in Carthamus tinctorius which may serve as potential candidates for functional characterization in future.
