Gene Details:

• Gene ID: Zm00001eb008680
• Gene Symbol: Ifa1
• Gene Name: indeterminate floral apex1
• Genome: Zm-B73-REFERENCE-NAM-5.0
• Species: Zea mays

Functional Descriptions:

• The defect found in Ifa1 mutants is specific to meristems and does not affect lateral organs.
• A role for Ifa1 in meristem identity in addition to meristem determinacy was revealed by double mutant analysis. In zea agamous1 (zag1) Ifa1 double mutants, the female floral meristem converts to a branch meristem whereas the male floral meristem converts to a spikelet meristem.
• We have discovered a gene in maize, indeterminate floral apex1 (Ifa1) that regulates meristem determinacy.
• Ifa1 regulates determinacy of spikelet pair, spikelet and floral meristems.
• Genetic interaction of Ifa1-r with mutants affecting floral and spikelet determinacy.
