TypeA glandular trichomes ofthewildpotato (Solanum berthaultii Hawkes) entrap insects byrapidly polymerizing thetrichomecontents after breakage byinsect contact. Polymerization oftrichome exudate appears tobedriven byasoluble polyphenol oxidase (PPO). PPOconstitutes upto70%oftheprotein inindividually collected trichomes andreaches a concentration approaching 200gMinthese organs. Trichome PPOhasbeenpurified andshowntobeamonomeric copper metalloprotein withan isoelectric point of5.5, possessing… CONTINUE READING
