The basic helix-loop-helix transcription factor, bHLH11 functions in the iron-uptake system in Arabidopsis thaliana

Iron (Fe) is a micronutrient that is essential for plant development and growth. Basic helix-loop-helix (bHLH) transcription factors are a superfamily of transcription factors that are important regulatory components in transcriptional networks in plants. bHLH transcription factors have been divided into subclasses based on their amino acid sequences and domain structures. Among the members of clade IVb (PYE, bHLH121, and bHLH11), the functions...
