We report the first identification of the female molecule that induces competency of the pollen tube to respond to the ovular attraction signal. This molecule, named AMOR, is an ovular arabinogalactan sugar chain, of which a terminal disaccharide, methyl- glucuronosyl galactose, is necessary and sufficient for activity.

Highlights

  • AMOR makes pollen tubes competent to respond to LURE attractant peptides in Torenia
  • Arabinogalactan sugars, which are abundant in the ovary, are responsible for AMOR
  • A terminal disaccharide structure is necessary and sufficient for AMOR activity
  • The synthesized disaccharide, methyl-glucuronosyl galactose, shows AMOR activity
