Gene Details:

• Gene ID: Zm00001eb250340
• Gene Symbol: EAD1
• Gene Name: ear apical degeneration1
• Genome: Zm-B73-REFERENCE-NAM-5.0
• Species: Zea mays

Functional Descriptions:

• The characterization of ear apical degeneration1 (EAD1) exhibiting strikingly shorter ears and the map-based cloning of the casual gene EAD1.
• EAD1 is a malate efflux transporter and loss of EAD1 leads to lower malate contents in the apical part of developing inflorescences.
• EAD1 is preferentially expressed in the xylem of immature ears and encodes an aluminum-activated malate transporter localizing to the plasma membrane.
• EAD1 plays essential roles in regulating maize ear development by delivering malate through xylem vessels to the apical part of the immature ear.
• EAD1 in malate-mediated female inflorescence development and provides a promising genetic resource for enhancing maize grain yield.
• mutants have strikingly shorter ears mutants have strikingly shorter ears.
