The antifungal activity of magnolol and honokiol, two naturally occurring hydroxylated biphenyls, their synthetic derivatives was evaluated on a collection representative isolates Fusarium oxysporum, F. solani verticillioides clinical ecological concern. tested compounds were proposed as 'natural' alternative to conventional fungicides, even though larger range concentrations (5–400 μg/ml) applied. honokiol compared with that terbinafine (0.1–10 μg/ml), fluconazole (1–50 fungicides widely...
At least 20 epidemics of Fusarium head blight (FHB) wheat have been registered in the last 50 years Argentina, with variable intensity. Damage induced by disease is further aggravated presence mycotoxins affected grains that may cause health problems to humans and animals. The trichothecene chemotype was analyzed for 112 isolates graminearum from Argentina polymerase chain reaction two field trials were conducted study aggressiveness a subsample 14 representative analyze deoxynivalenol (DON)...
Background: The use of antimicrobial peptides (AMPs) as biotechnological tools is an area growing interest in the research that seeks to improve crop defense. SmAPα1–21 and SmAPγ27–44 were previously reported inhibit Fusarium graminearum, permeabilize plasma membrane induce cytoplasmic disorganization. To exert its activity, initially enters through basal apical cells F. graminearum conidia then displays a general but non-homogeneous distribution cytoplasm all conidial cells, contrast....
Fusarium graminearum (Schwabe) contaminates agricultural crops and commodities with trichothecenes, mostly deoxynivalenol its acetyl-derivatives. Current techniques available to detect final mycotoxin contamination products usually require an extended time lag between sampling the corresponding report, include different clean-up steps eventually derivatisation. This study was aimed develop a methodology toxigenic F. prior production. Headspace solid-phase microextraction coupled capillary...
Fusarium graminearum is the etiological agent of head blight (FHB), a disease that produces significant decrease in wheat crop yield and it further aggravated by presence mycotoxins affected grains may cause health problems to humans animals. Plant defensins defensin-like proteins are antimicrobial peptides (AMPs); they small basic, cysteine-rich (CRPs) ubiquitously expressed plant kingdom mostly involved host defence. They present highly variable sequence but conserved structure. The γ-core...
Solid phase microextraction (SPME) coupled to capillary gas chromatography (CGC) and mass spectrometry (MS) was used evaluate the use of fungal volatiles discriminate Fusarium species from wheat cultivars in Argentina pampa region. Monosporic isolates were grown on rice sealed containers for 1 week volatile organic compounds (VOC) sampled 30 min head space by SPME analysed CGC CGCMS. VOC profiles F. graminearum, poae, equiseti, verticillioides oxysporum discriminated comparison their elution...
The green belt area surrounding the city of La Plata, Argentina, produces more than 70% (around 280 ha) lettuce (Lactuca sativa L.) cultivated under greenhouse for fresh consumption in country. In February 2011, April 2012, and December 2013, butterhead plants from cv. Lores showing wilt stunted growth symptoms, red-to-brown discoloration vascular tissues, yellow leaves were found greenhouses Plata. Sections tap root, crown stem symptomatic dark-brown streaking tissue surface sterilized...
Annually, ~20 ha of sweet basil (Ocimum basilicum L.) are cultivated in greenhouses the green belt area surrounding La Plata, Argentina, mainly for fresh consumption. In 2004 to 2007, plants cv. Genovese showed wilt symptoms, necrosis leaves and stems, asymmetrical growth, discolored vascular tissue Plata. same symptoms were observed on Morada grown from seeds that produced Italy. Isolations completed root, crown, stem sections diseased three commercial seeds, sections, flowers, 2007. Seeds...
Fusarium head blight (FHB) of wheat, caused by graminearum (Schwabe), is a destructive disease worldwide, reducing wheat yield and quality. To accelerate the improvement scab tolerance in we assessed International Triticeae Mapping Initiative mapping population (ITMI/MP) for Type I II resistance against wide Argentinean isolates F. graminearum. We discovered total 27 additive QTLs on ten different (2A, 2D, 3B, 3D, 4B, 4D, 5A, 5B, 5D 6D) chromosomes resistances explaining maximum 15.99%...
Aims:The purpose of this work was to compare the efficiency Bradyrhizobium japonicum and Ensifer fredii infect develop nodules on soybean.Furthermore we also evaluated competitive ability both species how altered by plant genotype soil pH.Study Design: The design experiments completely at random number replicates different each tested.
Differences in aggressiveness and mycotoxin production were previously found among isolates of Fusarium graminearum, the main incitant head blight (FHB) wheat, from Argentina. This study aims at evaluating genetic diversity present these its relationship with their aggressiveness. Inter-simple sequence repeats polymerase chain reaction (ISSR-PCR) was used to asses variability 112 F. graminearum 28 localities Buenos Aires Province, The analysis molecular variance (AMOVA) performed examine...
Several Fusarium species cause disease on human hosts, including commonly fatal infections in immunocompromised individuals. Recently, cases of hospitalized patients affected by fusaria were reported the Tyrrhenian Island Sardinia, Italy. To precisely characterize and haplotypes present hospitals region, a multilocus DNA sequence typing (MLST) approach was applied. Water distribution systems four departments belonging to Sardinian sampled. types (STs) identified using MLST based sequences...
More than 15,000 ha of tomato (Solanum lycopersicum L.) are annually cultivated under greenhouse and field conditions in Argentina.From December 2013 to 2016, plants cultivar 'Elpida' showing wilting stunting were observed commercial fields from Goya, Corrientes.This province concentrates the largest area greenhouses dedicated production country.Symptoms began as a yellowing lower leaves, which frequently was confined one side plant at first then spread rest it.When stems diseased cut...
