“…Trichoderma spp. are soil-borne and belongs to the genus of filamentous fungi, which can employ both direct and indirect biocontrol mechanisms, including biosynthesis of antimicrobial compounds, competition for nutrients and space, and induction of systemic resistance [ [33] , [34] , [35] , [36] ]. Trichoderma spp.…”

“…The positive correlations between R s and Actinobacteria and Dothideomycetes (order Pleosporales) were plausibly related to their contribution to an increase in available C sources through lignin degradation, which would produce a release of simpler compounds to soil (Vida et al, 2016). The positive correlation between R s and Hypocreaceae (genus Trichoderma) was likely related to their critical role in producing cell wall-degrading enzymes (chitinase, b-1,3-glucanase and cellulase) (Konappa et al, 2022). Although not directly correlated with R s , Agaricomycetes may also contribute to R s through their relevance in cellulose decomposition.…”

IntroductionCrops influence both soil microbial communities and soil organic carbon (SOC) cycling through rhizosphere processes, yet their responses to nitrogen (N) fertilization have not been well investigated under continuous monoculture.MethodsIn this study, rhizosphere soil microbial communities from a 5-year continuous mono-cropped peanut land were examined using Illumina HighSeq sequencing, with an N fertilization gradient that included 0 (N0), 60 (N60), 120 (N120) and 180 (N180) kg hm−2. Soil respiration rate (Rs) and its temperature sensitivity (Q10) were determined, with soil carbon-acquiring enzyme activities assayed.Results and discussionThe obtained results showed that with N fertilization, soil mineral N (Nmin) was highly increased and the soil C/N ratio was decreased; yields were unchanged, but root biomass was stimulated only at N120. The activities of β-1,4-glucosidase and polyphenol oxidase were reduced across application rates, but that of β-1,4-cellobiohydrolase was increased only at N120. Bacterial alpha diversity was unchanged, but fungal richness and diversity were increased at N60 and N120. For bacterial groups, the relative abundance of Acidobacteria was reduced, while those of Alphaproteobacteria and Gammaproteobacteria were increased at N60 and N120. For fungal members, the pathogenic Sordariomycetes was inhibited, but the saprotrophic Agaricomycetes was promoted, regardless of N fertilization rates. RDA identified different factors driving the variations in bacterial (root biomass) and fungal (Nmin) community composition. N fertilization increased Rs slightly at N60 and significantly at N120, mainly through the promotion of cellulose-related microbes, and decreased Rs slightly at N180, likely due to carbon limitation. N fertilization reduced microbial biomass carbon (MBC) at N60, N120 and N180, decreased SOC at N120 and N180, and suppressed dissolved organic carbon (DOC) at N180. In addition, the unchanged Q10 may be a joint result of several mechanisms that counteracted each other. These results are of critical importance for assessing the sustainability of continuously monocultured ecosystems, especially when confronting global climate change.

En la actualidad uno de los retos a los que se enfrentan los agricultores es producir alimentos bajo las inclemencias climáticas. Para el 2050, se estima un aumento en la demanda en producción de alimentos básicos a causa del incremento demográfico, aumentando con ello el detrimento de los recursos naturales. Dentro de las alternativas biológicas está el uso de insumos a base de microorganismos benéficos, como el género Trichoderma. Los cuales se han utilizado en los campos agrícolas para el control biológico contra un gran número de fitopatógenos. Sin embargo, aún son poco conocidas otras propiedades benéficas de este género para las plantas que coloniza y el ecosistema. Se realizó una búsqueda de artículos científicos en Academic Search Ultimate, BioOne, Acsess, Esmerald, Fuente Académica, ScienceDirect y Springer, entre 2015 y 2023, con dos excepciones de años anteriores. Se utilizó la palabra clave “Trichoderma” y aquellas relacionadas con interacciones microbianas y su aplicación agrícola. Esta revisión resume los hallazgos bibliográficos actuales de este género que muestran su alta capacidad hacia el desarrollo sostenible de los agroecosistemas. Varias investigaciones reportan su capacidad de inducir la defensa vegetal, la promoción del crecimiento y desarrollo radicular, así como la estimulación y síntesis de sustancias que contribuyen a fortalecer la fertilidad del suelo. Con ello mejora los rendimientos de los cultivos a los que se encuentra asociado. En definitiva, la aplicación de Trichoderma puede coadyuvar a disminuir los efectos negativos ocasionados por el uso de agroquímicos y fertilizantes sintéticos, contribuyendo a una producción más sostenible.
