Research Abstract

When PGPF including Trichoderma koningi, Fusarium equiseti, and Penicillium simplicissimum were inoculated onto L. japonicus roots, only T. koningi colonized the roots long-term and increased plant dry weight(126%). Roots colonized by T. koningi and the induction of a plant defense response were also revealed. These studies demonstrated that T. koningi possesses the ability to suppress the transcription of genes involved in biosynthesis of phytoalexins, and it made T. koningi possible to colonize in the rhizosphere.
