Gene Details:

  • Gene ID:
  • Gene Symbol: GhPSK
  • Gene Name: Phytosulfokine-α
  • Genome:
  • Species: Gossypium arboreum

Functional Descriptions:

  • A peptide hormone gene, GhPSK promotes fibre elongation and contributes to longer and finer cotton fibre.
  • A putative PSK gene (GhPSK) was cloned from Gossypium hirsutum. Expression pattern analysis revealed that GhPSK is preferentially expressed in rapidly elongating fibre cells (5–20 days postanthesis).
  • Overexpression of GhPSK in cotton increased the endogenous PSK-α level and promoted cotton fibre cell elongation, resulting in longer and finer fibres.
  • Digital gene expression (DGE) profile analysis of GhPSK overexpression lines indicates that PSK signalling may regulate the respiratory electron-transport chain and reactive oxygen species to affect cotton fibre development.
