Terpenoid and lipid profiles vary in different Phytophthora cactorum – strawberry interactions

Specialized metabolites are essential components in plant defence systems, serving as signalling molecules and chemical weapons against pathogens. The manipulation of metabolome or can thus be an important virulence strategy for Because their central role, give valuable insights into plant-pathogen interactions. Here, we have conducted nontargeted metabolite profiling with UPLC-ESI-qTOF-MS to investigate the metabolic changes that taken place crown tissue Fragaria vesca L. (woodland strawberry) × ananassa (Weston) Duchesne ex Rozier (garden during 48 h after Phytophthora cactorum challenge. Two P. isolates were compared: Pc407 is highly virulent F. causes rot, whereas Pc440 mildly virulent. In total, 45 differentially accumulated between treatment groups tentatively identified. Triterpenoids various lipid compounds represented. levels several triterpenoids increased upon inoculation, some them showing distinct accumulation patterns different could either inhibit stimulate growth and, therefore, triterpenoid profiles might significant impact on disease progression. Of compounds, lysophospholipids, linoleic acid linolenic most compatible - interaction. As lysophospholipids promote cell death been linked susceptibility, these involved pathogenesis rot disease. This analysis revealed potential factors contributing outcome – strawberry information valuable, it help find new breeding strategies solutions control strawberry.
