“…Metarhizium es un hongo que se encuentra en todo el mundo, siendo muy estudiado por diversos investigadores por su capacidad patogénica contra plagas agrícolas (Medina et al, 2020). Las especies nativas pueden ser altamente patogénicas alcanzando un índice de moralidad del 60% y esporulación del 80%, como lo demostraron Rodríguez y colaboradores en 2006 al utilizar cepas de Metarhizium anisopliae y Beauveria bassiana sobre Tuta absoluta.…”

Esta investigación tuvo como objetivo evaluar en laboratorio el potencial biocontrolador de Metarhizium anisopliae sobre Mocis latipes presente en pastos ganaderos del Municipio de Tantoyuca, Veracruz. La investigación se desarrolló en el año 2019; los microorganismos nativos se obtuvieron de 48 muestras compuestas de suelo, tomadas dentro de las unidades de producción ganaderas sin perturbación o poco transitadas, estas muestras se inocularon gusanos trampa (larvas de Galleria mellonella). Se aislaron tres cepas de Metarhizium anisopliae en medio agar-papa-dextrosa. Cada una de estas se inoculó sobre un grupo de 10 insectos adultos de Mocis latipes. Las pruebas de patogenicidad realizadas mostraron que los aislados nativos del género Metarhizium anisopliae, son promisorios para el control de Mocis latipes, con los que se puede plantear un control efectivo de esta especie a pesar de ser una plaga esporádica y voraz. Es necesario aplicar estas cepas en campo y evaluarlas en otras especies de insectos como mosca pinta (Aeneolamia spp., Prosapia spp.), las cuales son una plaga de importancia económica que afecta las gramineas forrajeras cultivadas en la Huasteca Veracruzana. El hongo Metarhizium anisopliae, el cual habita en diferentes tipos de suelo, podría ser usado para el control de plagas por su potencial como agente biocontrolador. Existen pequeñas poblaciones de este hongo en el suelo por lo que es necesario reproducirlas masivamente.

“…During interaction, alcohols, aldehydes, ketones, terpenes, aromatic compounds and reactive oxygen species (ROS) are produced as a result of antagonism (Evans et al 2008 ), which leads to the up-regulation of many oxidative enzymes like laccase, manganese peroxidase, lignin peroxidase (Gregorio et al 2006 ). For instance, dual culture of Trichoderma and Metarhizium leads to oxidative stress and production of sugar alcohols in the zone of interaction (Medina et al 2020 ). Tamayo et al ( 2016 ) reported that the increase in ROS activated enzymes like superoxide dismutases (SODs) which acted as first line of defense.…”

Melanin production and laccase mediated oxidative stress alleviation during fungal-fungal interaction among basidiomycete fungi

Fungal-fungal interaction often leads to the change in metabolite profile of both the interacting fungus which may have potential implication in industry or agriculture. In the present study, we performed two sets of fungal-fungal interaction—Trametes coccinea (F3) with Leiotrametes lactinea (F9) and T. coccinea (F3) with T. versicolor (F1) to understand the changes in the metabolite profile during the interaction process and how this process impacts the hyphal/mycelial morphology of the participating fungi. The metabolites produced during interaction of T. coccinea (F3) with L. lactinea (F9) and T. coccinea (F3) with T. versicolor (F1) was analysed through liquid chromatography coupled to mass spectroscopy (LC-MS). Most of the metabolites secreted or produced during interaction are associated with defensive response. Further, visualization with scanning electron microscopy revealed that interaction between the tested fungi led to the changes in the hyphal morphology. The bipartite fungal interaction resulted in the production of a dark brown colour pigment—melanin as confirmed by the LC-MS, FTIR and NMR analysis. Moreover, the fungal–fungal interaction also led to increase in the production of laccase, a group of multicopper oxidases involved in detoxification of toxic compounds. Further, increased activity of superoxide dismutase, an enzyme that catalyzes the dismutation of the superoxide anion to hydrogen peroxide was also recorded during fungal–fungal interaction. Quantitative real-time PCR revealed upregulation of lcc1 (encoding a laccase enzyme) and few other stress related genes of T. versicolor during its hyphal interaction with T. coccinea, suggesting a direct correlation between laccase production and melanin production.
