Milpa is an agroecological production system based on the polyculture of plant species, with corn featuring as a central component. Traditionally, milpa does not require application chemicals, and so pest attacks poor growth in soils can have adverse effects its production. Therefore, bioinoculants could be strategy for improving crop health; however, effect external inoculant agents endemic microbiota associated has been extensively studied. Here, objective this work was to fertilize maize under agrosystem PGPR Pseudomonas fluorescens UM270, evaluating impact diversity rhizosphere (rhizobiome) root endophytic (root endobiome) microbiomes plants. The endobiome roots evaluated by 16S rRNA internal transcribed spacer region (ITS) sequencing, rhizobiome assessed metagenomic sequencing upon inoculation strain UM270. results showed that UM270 P. did increase alpha either monoculture or milpa, but it alter microbiome stimulating presence bacterial operational taxonomic units (OTUs) genera Burkholderia (in monoculture), whereas, system, stimulated greater such Burkholderia, Variovorax, N-fixing rhizobia genera, including Rhizobium, Mesorhizobium, Bradyrhizobium. No clear association found between fungal beneficial fungi, Rizophagus irregularis Exophiala pisciphila, were detected system. In addition, network analysis revealed unique interactions species Stenotrophomonas sp., xenovorans, Sphingobium yanoikuyae, which potentially play roles plant. Finally, seem strong microbial rhizosphere, some functions, trehalose synthesis, ammonium assimilation, polyamine metabolism. biofertilizer plants modifies rhizo- high potential health models.

Importance of Dark Septate Endophytes in Agriculture in the Face of Climate Change

Journal of Fungi, Год журнала: 2024, Номер 10(5), С. 329 - 329

Climate change is a notable challenge for agriculture as it affects crop productivity and yield. Increases in droughts, salinity, soil degradation are some of the major consequences climate change. The use microorganisms has emerged an alternative to mitigate effects Among these microorganisms, dark septate endophytes (DSEs) have garnered increasing attention recent years. Dark shown capacity mitigating reducing harmful agriculture, such drought, reduced nutrient availability soil. Various studies show that their association with plants helps reduce abiotic stresses increases availability, enabling thrive under adverse conditions. In this study, effect DSEs underlying mechanisms help develop higher tolerance were reviewed.

Dark septate endophyte Exophiala pisciphila promotes maize growth and alleviates cadmium toxicity

Frontiers in Microbiology, Год журнала: 2023, Номер 14

Dark septate endophytes (DSE) are typical root with the ability to enhance plant growth and tolerance heavy metals, but underlying mechanisms unclear. Here, physiological molecular of a DSE strain, Exophiala pisciphila, in mitigating cadmium (Cd, 20 mg/kg) toxicity maize were investigated. Our results showed, under Cd stress, E. pisciphila inoculation enhanced biomass reduced both inorganic soluble forms (high toxicity) by 52.6% leaves, which may be potentially contributing mitigation. Besides, significantly affected expression genes involved signal transduction polar transport phytohormone, then abscisic acid (ABA) indole-3-acetic (IAA) contents roots, was main reason for promoting growth. In addition, also made 27% increase lignin content regulating synthesis it, beneficial hinder Cd. activated glutathione metabolism up-regulation related S-transferase. This study helps elucidate functions sheds light on mechanism detoxifying provides new insights into protection crops from metals.

Epichloë gansuensis Increases the Tolerance of Achnatherum inebrians to Low-P Stress by Modulating Amino Acids Metabolism and Phosphorus Utilization Efficiency

Journal of Fungi, Год журнала: 2021, Номер 7(5), С. 390 - 390

Опубликована: Май 17, 2021

In the long-term evolutionary process, Achnatherum inebrians and seed-borne endophytic fungi, Epichloë gansuensis, formed a mutually beneficial symbiosis relationship, gansuensis has an important biological role in improving tolerance of host grasses to abiotic stress. this work, we first assessed effects on dry weight, content C, N, P metal ions, metabolic pathway amino acids, phosphorus utilization efficiency (PUE) at low Our results showed that weights, alanine, arginine, aspartic acid, glycine, glutamine, glutamic L-asparagine, lysine, phenylalanine, proline, serine, threonine, tryptophan were higher leaves gansuensis-infected (E+) than gansuensis-uninfected (E-) Further, increased C roots compared root E- plant 0.01 mM 0.5 P; Epichloëgansuensis K leaf P. reduced Ca Mg Fe addition, stress, most probably influenced aspartate glutamate metabolism; valine, leucine, isoleucine biosynthesis leaves; arginine proline aspartate, metabolism roots. also affected organic acid stress-related metabolites conclusion, improves growth stress by regulating acids content, increasing PUE.

The origin of human pathogenicity and biological interactions in Chaetothyriales

Fungal Diversity, Год журнала: 2023, Номер 125(1), С. 99 - 120

Опубликована: Март 1, 2023

Abstract Fungi in the order Chaetothyriales are renowned for their ability to cause human infections. Nevertheless, they not regarded as primary pathogens, but rather opportunists with a natural habitat environment. Extremotolerance is major trend order, quite different from black yeasts Capnodiales which focus on endurance, an important additional parameter advancing toxin management. In ancestral ecology of rock colonization, association metabolite-producing lichens significant. Ant-association, dealing pheromones and repellents, another mainstay order. The phylogenetically derived family, Herpotrichiellaceae , shows dual monoaromatic hydrocarbon assimilation disease humans cold-blooded vertebrates. this study, data ecology, phylogeny, genomics were collected analyzed support hypothesis evolutionary route species . Comparing ribosomal tree that enzymes involved toluene degradation, significant expansion cytochromes observed catabolism found be complete some Herpotrichiellaceae. This might enhance systemic infection. However, since most have traumatically inoculated disease, invasive potential categorized opportunism. Only chromoblastomycosis, true pathogenicity surmised. criterion would possible escape agents vertebrate host, enabling dispersal adapted genotypes subsequent generations.
