Gene Details:

• Gene ID: TraesCS7A03G0422300
• Gene Symbol: TaTPP-7A
• Gene Name: Trehalose-phosphatase
• Genome: Chinese_Spring1.0
• Species: Triticum aestivum

Functional Descriptions:

• TaTPP-7A is a crucial domestication- and breeding-targeted gene and it feedback regulates sucrose lysis, flux, and utilization in the grain endosperm mainly through the T6P-SnRK1 pathway and sugar–ABA interaction.
• TaTPP-7A encodes a functional T6P dephosphorylation enzyme of the Tre pathway and is highly expressed in the aleurone layer of the developing grains.
• TaTPP-7A promotes grain development and filling, resulting in higher TKW and early maturity.
• TaTPP-7A affects endosperm amylose content, influencing starch gelatinization temperature and processing quality.
• TaTPP-7A enhances starch synthesis and grain filling mainly through T6P-SnRK1 pathway and sugar–ABA interaction.
