Gene Details:

• Gene ID: Zm00001eb071990
• Gene Symbol: ZmLFY1 zfl2
• Gene Name: Zea floricaula leafy2
• Genome: Zm-B73-REFERENCE-NAM-5.0
• Species: Zea mays

Functional Descriptions:

• zfl1 and zfl2 double mutants exhibit a disruption of floral organ identity and patterning, as well as defects in inflorescence architecture and in the vegetative to reproductive phase transition.
• Despite overlap in traits associated with these duplicate genes, zfl1 showed stronger associations with flowering time, while zfl2 associated more strongly with branching and inflorescence structure traits, suggesting some divergence of function.
• The results suggest that zfl2 activity is important for the QTL effect, supporting zfl2 as a candidate gene for a role in morphological evolution of maize.
• ZmLFY1 a candidate maize domestication gene controlling ear rank number.
• The mutant phenotype observed in flowers specifically suggests a conserved role for the zfl genes as upstream regulators of the maize counterparts of the dicot ABC floral organ identity genes.
