Gene Details:

  • Gene ID:
  • Gene Symbol: ScRALF3
  • Gene Name: rapid alkalinization factor 3
  • Genome:
  • Species: Solanum chacoense

Functional Descriptions:

  • ScRALF3, a secreted RALF-like peptide involved in cell–cell communication between the sporophyte and the female gametophyte in a solanaceous species.
  • ScRALF3 is an important peptide regulator of female gametophyte development. Its expression, which is auxin-inducible, is strictly regulated before and after fertilization. Down-regulation of ScRALF3 expression by RNA interference leads to the production of smaller fruits that produce fewer seeds, due to improper development of the embryo sacs.
  • ScRALF3 is expressed in the sporophytic tissue surrounding the embryo sac, the integument and the nucellus, as revealed by in situ hybridization and GUS staining.
  • As expected for a secreted peptide, fluorescence from an ScRALF3–GFP fusion construct is detected throughout the secretory pathway.
  • The ScRALF3 secreted peptide may be directly involved in the regulation of multiple aspects of cell–cell communication between the female gametophyte and its surrounding sporophytic tissue during ovule development.
