Outline of Final Research Achievements

Trichoderma koningii one of plant growth-promoting fungi suppresses the expression of resistant genes involved in production of phytoalexin in Lotus japonicus and establishes an associative symbiosis. it seems to failed to irrupt into the inside of roots and establish the symbiosis since it could not suppress the expression of the resistant genes when T. koningii was inoculated on Lotus japonicus mutated on the symbiosis pathway. It suggests that T. koningii might require the symbiosis pathway for associative symbiosis with Lotus japonicus.
