Gene Details:

• Gene ID: Zm00001eb377480
• Gene Symbol: ZmHb77
• Gene Name: Homeobox-transcription factor 77
• Genome: Zm-B73-REFERENCE-NAM-5.0
• Species: Zea mays

Functional Descriptions:

• Identified the transcription factor ZmHb77 that affects overall root architecture by increasing SRN but suppressing lateral root density.
• ZmHb77 acts as a central modulator contributing to the promotion of seminal root formation but inhibition of lateral root density in maize seedlings. Such root architectural and functional plasticity provides maize seedlings with great potential to balance external water constraints.
• ZmHb77 regulates root system architecture and drought resilience.
• Functional characterization of the transcription factor ZmHb77 and in silico root modeling provides evidence that reshaping root system architecture by reducing the number of seminal roots and promoting lateral root density is benefcial for the resilience of maize seedlings to drought.
