Gene Details:

• Gene ID: GRMZM5G838324
• Gene Symbol: Cg1
• Gene Name: Corngrass1
• Genome: B73_RefGen_v3
• Species: Zea mays

Functional Descriptions:

• Furthermore, a target of Cg1 is teosinte glume architecture1 (tga1)1, a gene known to have had a role in the domestication of maize from teosinte.
• Cg1 mutant plants overexpressing miR156 have lower levels of mir172, a microRNA that targets genes controlling juvenile development2.
• The Cg1 reference allele (Cg1-R) affects multiple aspects of development, from leaf initiation to floral architecture.
• These phenotypes suggest that the Cg1 gene and its targets are responsible for initiating the switch from juvenile to adult vegetative development as well as maintaining that switch during floral development.
• Cg1 increase in number of brace root whorls.
• Cg1 encodes two tandem miR156 genes that are overexpressed in the meristem and lateral organs.
