Gene Details:

• Gene ID: Zm00001eb237270
• Gene Symbol: sxd1
• Gene Name: sucrose export defective1
• Genome: Zm-B73-REFERENCE-NAM-5.0
• Species: Zea mays

Functional Descriptions:

• Tie-dyed1 and Sucrose export defective1 act independently to promote carbohydrate export from maize leaves.
• As tdy1 and sxd1 are the only variegated leaf mutants known to accumulate carbohydrates in any plant, we investigated whether Tdy1 and sxd1 function in the same pathway.
• Double mutant plants showed an additive interaction for growth related phenotypes and soluble sugar accumulation, and expressed the leaf variegation pattern of both single mutants indicating that Tdy1 and sxd1 act in separate genetic pathways.
• Tdy1 and sxd1 function independently to promote carbon export from leaves. Our genetic and cytological studies implicate Tdy1 functioning in veins, and a model discussing possible functions of TDY1 is presented.
