First report of Trichoderma guizhouense isolated from soil in Türkiye

Trichoderma species (Hypocreaceae) is one of the world's most common widely used plant growth-promoting fungus and, ecologically and economically important genus. A survey was conducted for species of the genus Trichoderma from 165 soil samples in Aydin province, Turkiye in 2018 and 2019. We obtained 88 isolates of the genus Trichoderma with macroscopic and molecular features were identified from soil samples. Single conidia colonies of Trichoderma isolates were cultured different media for morphological characteristics. Tr49 isolate was recognized Trichoderma guizhouense and this isolate isolation of soil samples from red beet (Beta vulgaris subsp. vulgaris var. conditiva) field. The isolate was identified grounded on molecular and phylogenetic analysis with three gene (ITS; internal transcribed spacer, tef1-alpha; translation elongation factor 1 alpha, rpb2; RNA polymerase II subunit) primers. To our knowledge, this study provides the first report of Trichoderma guizhouense in soil in Turkiye.
