Gene Details:

• Gene ID: Zm00001eb381400
• Gene Symbol: ZmEXPB15 expb15
• Gene Name: Zm00001eb381400
• Genome: Zm-B73-REFERENCE-NAM-5.0
• Species: Zea mays

Functional Descriptions:

• The expression of ZmEXPB15 is under the direct control of two nucellus-enriched genes, ZmNAC11/ZmNAC29, which control kernel size by a similar mechanism.
• ZmNAC11 and ZmNAC29, activate ZmEXPB15 expression. Accordingly, these two TFs also promote kernel size and weight through nucellus elimination regulation.
• Increased kernel weight of hybrids overexpressing ZmEXPB15 demonstrates its potential application value of maize breeding.
• ZmEXPB15 acts genetically with ZmNAC11 and ZmNAC29 to control kernel weight.
• Mutations in ZmNAC11 and ZmNAC29 cause similar kernel defects to ZmEXPB15.
• ZmEXPB15 may be involved in seed expansion during kernel development.
