Overview

Finds biocontrol and phytostimulant properties in Trichoderma isolates, suggesting agricultural applications.

Key Points

  • This research aims to characterize novel Trichoderma spp. isolates for their growth-promoting and biocontrol properties in plants.
  • Collected 27 Trichoderma isolates from Tucumán, Argentina.
  • Conducted in vitro assays to test antifungal activity against key fungal pathogens.
  • Evaluated root growth responses of Arabidopsis thaliana to secreted compounds from isolates.
  • Selected five promising isolates for further greenhouse testing in A. thaliana.
  • Monitored biomass, leaf area, and gene expression related to growth and defense.
  • Selected isolates showed enhanced biomass and leaf area in A. thaliana.
  • Specific gene expression changes were observed, indicating altered growth and immune responses.
  • Treated plants responded differently based on the isolate used, demonstrating isolate-specific effects.
