Can the DSE Fungus Mitigate the Effect of Salinity on the Grass ?

Dark septate endophytes (DSEs) are commonly found in saline environments, such as the Flooding Pampas (Argentina), where the forage grass has been introduced. This study evaluated the effect of salinity on the DSE fungus , isolated from , and its contribution to the grass's salinity tolerance. Two greenhouse experiments were conducted under three salinity levels (0, 40, and 80 meq Na·L), with and without fungal inoculation.

Cover Crops Modulate the Response of Arbuscular Mycorrhizal Fungi to Water Supply: A Field Study in Corn.

Cover crops (CCs) were found to improve soil health by increasing plant diversity and ground cover. They may also improve water supply for cash crops by reducing evaporation and increasing soil water storage capacity. However, their influence on plant-associated microbial communities, including symbiotic arbuscular mycorrhizal fungi (AMF), is less well understood.

Protein corona on biogenic silver nanoparticles provides higher stability and protects cells from toxicity in comparison to chemical nanoparticles.

The development of environmentally friendly new procedures for the synthesis of metallic nanoparticles is one of the main goals of nanotechnology. Proteins and enzymes from plants, filamentous fungi, yeast, and bacteria to produce nanoparticles are both valuable and viable alternatives to conventional synthesis of nanomaterials due to their high efficiency and the low cost to scale up and generate large quantities. The aim of this work is to compare biogenic silver nanoparticles (AgNPs) obtained from cell-free filtrates from the fungus Macrophomina phaseolina to conventional chemical AgNPs, in biocidal activity and toxicity.

Tolerance of dark septate endophytic fungi (DSE) to agrochemicals in vitro.

Dark septate endophytes (DSE) are a heterogeneous group of fungi, mostly belonging to the Phylum Ascomycota, that are involved in a mutualistic symbiosis with plant roots. The aim of this study is to evaluate the behavior of two strains of DSE isolated from wheat roots of two cropping areas in the province of Buenos Aires, Argentina, against some agrochemicals. Of all the isolates obtained, two strains were identified as Alternaria alternata and Cochliobolus sp.

Extracellular biosynthesis of bactericidal Ag/AgCl nanoparticles for crop protection using the fungus Macrophomina phaseolina.

Synthesis of noble metal nanoparticles using natural products and living organisms has drawn a lot of interest owing to economic prospects and potential applicability in different fields. For this work we used the exudate of the soil fungus Macrophomina phaseolina for a low-cost method of green synthesis to obtain stable silver-silver chloride nanoparticles (Ag/AgCl-NPs). Reaction parameters including media and AgNO concentration were further optimized for NPs production.

Arbuscular mycorrhiza detoxifying response against arsenic and pathogenic fungus in soybean.

Unlabelled: Uptake of Arsenic (As) in plant tissues can affect metabolism, causing physiological disorders, even death. As toxicity, but also pathogen infections trigger a generalised stress response called oxidative stress; however knowledge on the response of soybean (Glycine max L.) under multiple stressors is limited so far.
