Abstract:
A collection of Trichoderma isolates, with different biocontrol capabilities, were identified by molecular methods. Arbitrarily-primed PCR (ap-PCR) using repeat motif primers was performed on DNA from a Trichoderma spp. collection of 76 isolates, and representative isolates were further characterized into three main clades by internal transcribed spacer (ITS) sequence analysis. Consequently, a reliable phylogenetic tree was constructed containing isolates belonging to the T. harzianum clade (comprising T. aureoviride, T. inhamatum, and T. virens), the T. longibrachiatum and T. saturnisporum cluster, and that including the species T. asperellum, T. atroviride, T. koningii and T. viride.
