Gene Details:

• Gene ID:
• Gene Symbol: StPP2Ac2b
• Gene Name: protein phosphatase 2A catalytic subunit
• Genome:
• Species: Solanum tuberosum

Functional Descriptions:

• The protein phosphatase 2A catalytic subunit StPP2Ac2b is involved in the control of potato tuber sprouting and source–sink balance in tubers and sprouts.
• StPP2Ac2b overexpression delays tuber sprouting and affects apical dominance and sprout growth.
• We also determined that StPP2Ac2b is involved in the regulation of starch and sucrose metabolism, the response to GA, and the control of source–sink balance in tubers and sprouts.
• Demonstrating that the catalytic subunit StPP2Ac2b positively modulates tuber induction, and that its function is related to the regulation of gibberellic acid metabolism.
• Overexpression of StPP2Ac2b alters the source–sink balance, increasing the source capacity of the tuber, and the sink strength of the sprout to support its accelerated growth.
