Gene Details:

  • Gene ID:
  • Gene Symbol: StGA2ox1
  • Gene Name: Gibberellin 2-oxidase 1
  • Genome:
  • Species: Solanum tuberosum

Functional Descriptions:

  • StGA2ox1 is induced prior to stolon swelling and controls GA levels during potato tuber development.
  • StGA2ox1 is upregulated during the early stages of potato tuber development prior to visible swelling and is predominantly expressed in the subapical region of the stolon and growing tuber.
  • Transgenic plants with reduced expression levels of StGA2ox1 showed normal plant growth, an altered stolon swelling phenotype and delayed in vitro tuberization.
  • Over-expression and suppression of StGA2ox1 expression results in altered growth characteristics and tuber morphology.
  • We propose a role for StGA2ox1 in early tuber initiation by modifying GA levels in the subapical stolon region at the onset of tuberization, thereby facilitating normal tuber development and growth.
