Gene Details:

• Gene ID: Zm00001eb312340
• Gene Symbol: Ra1
• Gene Name: ramosa1
• Genome: Zm-B73-REFERENCE-NAM-5.0
• Species: Zea mays

Functional Descriptions:

• The Cys2-His2 zinc-finger transcription factor RAMOSA1 (Ra1) regulates the fate of most axillary meristems during the early development of maize inflorescences, the tassel and the ear, and has been implicated in the evolution of grass architecture.
• Mutations in Ra1 or any other known members of the ramosa pathway, RAMOSA2 and RAMOSA3, generate highly branched inflorescences.
• REL2/Ra1 transcriptional repressor complex antagonizes the formation of indeterminate branches during maize inflorescence development.
• Despite genetic and expression analysis that place both RA2 and RA3 genes upstream of Ra1 in regulating spikelet-pair meristem identity and fate.
