Gene Details:

• Gene ID: Zm00001eb180830
• Gene Symbol: ZmSWEET15a ZmSWEET10 ZmSWEET9
• Gene Name:
• Genome: Zm-B73-REFERENCE-NAM-5.0
• Species: Zea mays

Functional Descriptions:

• ZmSWEET14a/15a and ZmSUT4 are responsible for sucrose transport from the periembryonic region (endosperm) to the embryo, respectively.
• ZmSWEET15a likely exporting sucrose but enhanced the expression of most transporter genes for uptake of apoplasmic sugars.
• The expression of ZmSUT1 in the BETL suggests that sucrose uptake may occur in parallel with hexose import facilitated by ZmSTPs and ZmSWEET3a/4c, thereby contributing further to sugar transport in the maize grain.
