Gene Details:

• Gene ID: Zm00001eb297040
• Gene Symbol: Tdy1
• Gene Name: tie-dyed1
• Genome: Zm-B73-REFERENCE-NAM-5.0
• Species: Zea mays

Functional Descriptions:

• Tie-dyed1 Encodes a Novel, Phloem-Expressed Transmembrane Protein That Functions in Carbohydrate Partitioning.
• Tdy1 encodes a novel transmembrane protein present only in grasses, although two protein domains are conserved across angiosperms.
• Tdy1 is expressed exclusively in phloem cells of both source and sink tissues, suggesting that Tdy1 may play a role in phloem loading and unloading processes.
• Tdy1 RNA accumulates in protophloem cells upon differentiation, suggesting that Tdy1 may function as soon as phloem cells become competent to transport assimilates.
• Even though Tdy1 RNA accumulates in source and sink tissues, we propose that Tdy1 functions in carbon partitioning by promoting phloem loading.
• Tie-dyed1 and sucrose export defective1 act independently to promote carbohydrate export from maize leaves.
