Resumen

Objective: the present work was done with the objective of identifying endophytic fungi associated with Theobroma cacao L. in Centro, Cunduacán and Comalcalco, locations in the state of Tabasco, Mexico. The molecular identity used was the region of the Internal Transcribed Spaces (ITS), ITS 1 and ITS 4. Design/methodology/approach: the study identified 15 fungal strains, grouped into 13 different species, belonging to the Ascomycota phylum, distributed in three different classes: Dothideomycetes, Eurotiomicetos and Sordariomycetes. It is important to mention that it is the first record of Endomelanconiopsis endophytica and freycinetiae found in cacao in Tabasco. In addition, we also identified Aspergillus foetidus, fischeri, delicatus arcoverdensis; Thielaviopsis ethacetica, Cophinforma atrovirens, Neurospora udagawae, Diaporthe miriciae, Nodulisporium indicum, Cophinforma atrovirens; Colletotrichum tainanense y hebeiense. Findings/conclusions: Many of these endophytic fungi produce secondary metabolites and antioxidants that can be used in the medical industry or for biological control of phytopathogenic diseases, such as Moniliophthora roreri.
