Genome-Wide Identification and Analysis of bHLH Transcription Factors Related to Anthocyanin Biosynthesis in Cymbidium ensifolium.

ABSTRACT: The basic helix-loop-helix (bHLH) transcription factors are widely distributed across eukaryotic kingdoms and participate in various physiological processes. To date, the bHLH family has been identified and functionally analyzed in many plants. However, systematic identification of bHLH transcription factors has yet to be reported in orchids. Here, 94 bHLH transcription factors were identified from the Cymbidium ensifolium genome and divided into 18 subfamilies. Most CebHLHs contain numerous cis-acting elements associated with abiotic stress responses and phytohormone responses. A total of 19 pairs of duplicated genes were found in the CebHLHs, of which 13 pairs were segmentally duplicated genes and six pairs were tandemly duplicated genes. Expression pattern an
