CARAVANTES-PEREZ, Alejandra et al. Trichoderma species from rhizospheric soil and Agave potatorum tissues. Ecosistemas y recur. agropecuarios [online]. 2025, vol.12, n.3, e4270.  Epub 05-Dic-2025. ISSN 2007-901X.  https://doi.org/10.19136/era.a12n3.4270.

Fungi of genus Trichoderma are found in different habitats. The interest in their study is by the secondary metabolites production. Although the favorable conditions for their growth are in relative humidity greater than 70%, the discovery of these fungi in semiarid zones exposes the plasticity of native species to adapt and the opportunity to learn about their mechanisms of action. The research objective was to characterize the morphology, taxonomy and enzymatic biochemistry of Trichoderma species from rhizospheric soil and A. potatorum tissues. In 2023, soil and plants of A. potatorum were collected in Chichicapam, Oaxaca. From these samples, four Trichoderma species were identified and characterized by morphology, taxonomy, growth speed, conidia production and exoglucanases and chitinases activity. The species had significant differences in morphometric, taxonomic and enzymatic characters. T. asperellum, T. yunnanense and T. lentiforme were identified as fungi of A. potatorum soil and tissue.
