Description
Summary:, also known as pinewood nematode (PWN), is the pathogenic agent of pine wilt disease (PWD), which affects pine trees around the world. Infection spread globally through international wood commerce and locally by vector beetles, threatening the wood world economy. As climate changes, more countries are becoming susceptible to PWD and, to prevent disease spread and limit economic and ecological losses, better knowledge about this pathogenic agent is needed. strains, present in the endophytic community of pine trees and carried by PWN, may play an important role in PWD. This work aimed to better understand the interaction between strains and and to assess the nematicidal potential of serratomolide-like molecules produced by strains. Serrawettin gene presence was evaluated in selected strains. Mortality tests were performed with bacteria supernatants, and extracted amino lipids, against (model organism) and to determine their nematicidal potential. Attraction tests were performed with . Concentrated supernatants of strains with serratamolide-like lipopeptides were able to kill more than 77% of after 72 h. Eight specific amino lipids showed a high nematicidal activity against . We conclude that, for some strains, their supernatants and specific amino lipids showed nematicidal activity against .
