Gene Details:

• Gene ID: Zm00001eb194460
• Gene Symbol: bHLH155
• Gene Name: bHLH-transcription factor 155
• Genome: Zm-B73-REFERENCE-NAM-5.0
• Species: Zea mays

Functional Descriptions:

• We functionally characterized two genes encoding atypical basic-helix–loop–helix (bHLH) transcription factors, bHLH30 and its homolog bHLH155, which are highly expressed in the elongated adaxial cells.
• Genetic analyses revealed that bHLH30 and bHLH155 positively regulate LA expansion, and molecular experiments demonstrated their ability to activate the transcription of genes involved in cell elongation and lignification of SCs.
• Identified two atypical basic-helix–loop–helix (bHLH) transcription factors, bHLH30 and its homolog bHLH155, that are specifically expressed in the ligular region and associate with the promoter regions of maize alpha expansin 5 (EXPA5) and phenylalanine ammonia lyase 7 (PAL7), activating their transcription and thereby promoting LA expansion.
• Maize bHLH30 and bHLH155 positively regulate LA expansion.
