Gene Details:

• Gene ID: Zm00001eb350590
• Gene Symbol: ZmSWEET3a ZmSWEET15 ZmSWEET16
• Gene Name: sugars will eventually be exported transporter3a
• Genome: Zm-B73-REFERENCE-NAM-5.0
• Species: Zea mays

Functional Descriptions:

• Extracellular sucrose is hydrolyzed to monosaccharides by cell wall acid invertase and subsequently absorbed as monosaccharides by the monosaccharide transporters ZmSTP3 and Zmsweet31/4C.
• ZmSWEET3a 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.
