Gene Details:

• Gene ID: PGSC0003DMG400009891
• Gene Symbol: StAmy23
• Gene Name: alpha-amylase 23
• Genome: potato genome sequence consortium database (http://solanaceae.plantbiology.msu.edu/pgsc_download.shtml)
• Species: Solanum tuberosum

Functional Descriptions:

• StAmy23 is localized in the cytoplasm, whereas StBAM1 and StBAM9 are targeted to the plastid stroma and starch granules, respectively.
• StAmy23 silencing resulted in higher phytoglycogen and lower RS accumulation in cold-stored tubers, implying that StAmy23 regulates CIS by degrading cytosolic phytoglycogen.
• StAmy23 and StBAM1 preferentially operate on soluble starch, but StBAM9 acts on starch granules.
• Our findings suggest that StAmy23, StBAM1, and StBAM9 function in potato CIS with varying levels of impact.
