Gene Details:

• Gene ID: Zm00001eb175150
• Gene Symbol: TGA1
• Gene Name: teosinte glume architecture1
• Genome: Zm-B73-REFERENCE-NAM-5.0
• Species: Zea mays

Functional Descriptions:

• The transition between these two plants involved the retraction of fruit cases, which allowed a stronger, thicker, and higher-yield cob. Although this is a remarkable change, the only gene identified to contribute to this has been the transcription factor Teosinte glume architecture 1 (TGA1).
• In a new publication, Jiahn-Chou Guan and colleagues (Guan et al., 2022) reveal that strigolactones (SLs) regulate many aspects of maize domestication phenotypes by modulating the accumulation of TGA1.
• TGA1 ia one of the domestication traits that made maize distinct from teosine.
• TGA1 increase in number of brace root whorls.
