Genome- and Transcriptome-Wide Characterization and Expression Analyses of bHLH Transcription Factor Family Reveal Their Relevance to Salt Stress Response in Tomato.

ABSTRACT: The bHLH (basic helix-loop-helix) transcription factors function as crucial regulators in numerous biological processes including abiotic stress responses and plant development. According to our RNA-seq analysis of tomato seedlings under salt stress, we found that, although the bHLH gene family in tomato has been studied, there are still so many tomato bHLH genes that have not been identified and named, which will hinder the later study of SlbHLHs. In total, 195 SlbHLHs that were unevenly distributed onto 12 chromosomes were identified from the tomato genome and were classified into 27 subfamilies based on their molecular features. The collinearity between SlbHLHs and interrelated orthologs from 10 plants further revealed evolutionary insights into SlbHLHs. Cis-element
