Gene Details:

Functional Descriptions:

  • A gamma-thionin protein from apple, MdD1, is required for defence against S-RNase-induced inhibition of pollen tube prior to self/non-self recognition.
  • MdD1 was shown to bind to the RNase activity sites of S-RNase leading to inhibition of enzymatic activity.
  • MdD1 acts as a primary defence protein in apple pollen tubes facilitating compatible pollen tube growth in the presence of S-RNase.s
  • MdD1 directly interacts with the active sites of S-RNase and inhibits its activity following S-RNase entry into the pollen tube.
  • This work provides intriguing insights into an ancient defence mechanism present in apple pollen tubes where MdD1 likely acts as a primary line of defence to inhibit S-RNase cytotoxicity prior to self/non-self recognition.
