Economic losses caused by postharvest diseases represent one of the main problems citrus industry worldwide. The major affecting are "green mold" and "blue mold", Penicillium digitatum P. italicum, respectively. To control them, synthetic fungicides most commonly used method. However, often emergence resistant strains occurs their use is becoming more restricted because toxic effects environmental pollution they generate, combined with trade barriers to international markets. aim this work...
Food losses, defined as a reduction in the quantity and quality of food during production storage, impact safety security. Losses caused by plant pathogens are among most significant. Chemical pesticides have been extensively used to prevent microbial diseases. Their toxicity reduced efficacy, however, encouraged investigators develop alternatives. Alternatives based on biopesticides tend be safer more environmentally benign than conventional pesticides. In recent years, formulations...
Argentina is among the most important lemon fruit producers in world. Penicillium digitatum primary fungal phytopathogen, causing green mold during postharvest. Several alternatives to use of synthetic fungicides have been developed, being biocontrol yeasts one promising. Although many reports are based on a single yeast species, it has shown that combination agents with different mechanisms action can increase control efficiency through synergistic effects. The combined native had not...
ABSTRACT Actinobacteria have frequently been reported in the Andean Puna, including strains of genus Micrococcus . These demonstrate resistance to high levels UV radiation, arsenic, and multiple antibiotics, possess large linear plasmids. A comparative analysis sequences putative functions these plasmids was conducted. The presence regions with sequence identity (exceeding 30 kb total) all three studied megaplasmids indicates a clear evolutionary link among elements. Genes related essential...
Abstract Background Postharvest lemons are affected by several fungal infections, and as alternatives to chemical fungicides for combating these different microbial biocontrol agents have been studied, with the Clavispora lusitaniae 146 strain standing out. Although has proven be an effective agent, influence of a biological control agent on postharvest lemon microbiome not studied until now. Thus, this study aimed evaluate how epiphytic is application yeast C. 146. Results In terms...
Abstract Ceratitis capitata (Wiedemann) is a cosmopolitan pest of economic importance. It controlled by using the Sterile Insect Technique (SIT), which involves rearing and release sterile males destined to mate with wild females, causing generation‐to‐generation suppression. Medflies are colonized microorganisms, primarily Enterobacteriaceae, genera Klebsiella Enterobacter being most common. Such microbiota contributes host fitness. During SIT, diet antibiotics irradiation for sterility...
High altitude Andean lakes are placed in Puna desert over 4400 above sea level. Completely isolated, they exposed to extreme environmental factors like high levels of salinity, UV radiation and heavy metals low concentrations phosphorus. Nevertheless, the habitat enormous populations three flamingo species that migrate among these Lakes. Previous reports have determined bacteria isolated from environments present resistance antibiotics. The aim this work was determine diversity antibiotic...
Fungal rots are one of the main causes large economic losses and deterioration in quality nutrient composition fruits during postharvest stage. The yeast Clavispora lusitaniae 146 has previously been shown to efficiently protect lemons from green mold caused by Penicillium digitatum. In this work, effect concentration exposure time on biocontrol efficiency was assessed; protection various citrus against P. digitatum C. evaluated; ability strain degrade mycotoxin patulin tested; treatment...
Blueberry production is affected by fungal postharvest pathogens, including Botrytis cinerea and Alternaria alternata, the causative agents of gray mold disease rot, respectively. Biocontrol adapted to blueberries local environments are not known date. Here, we report on search for identification cultivable blueberry epiphytic bacteria with potential combat aforementioned fungi. Native, blueberry-borne bacterial strains were isolated from a plantation in Tucumán, Argentina classified based...
Mobile genetic elements, including plasmids, drive the evolution of prokaryotic genomes through horizontal transfer genes allowing exchange between bacteria. Moreover, plasmids carry accessory genes, which encode functions that may offer an advantage to host. Thus, it is expected in a certain ecological niche, are enriched functions, important for their hosts proliferate niche. Puquio de Campo Naranja high-altitude lake from Andean Puna exposed multiple extreme conditions, high UV radiation,...
Worldwide, the green rot caused by Penicillium digitatum is one of most aggressive postharvest diseases lemons. Searching for sustainable alternatives to chemical fungicides, epiphytic yeasts as potential biocontrol agents were isolated from citrus fruits using a tailor-made selective medium. For disclosing their antagonistic against P. digitatum, obtained isolates subjected direct screening methods, both in vitro and vivo. In course primary that comprised dual culture assays, 43 yeast...
Botrytis cinerea is the causal agent of gray mold, which affects a wide variety plant species. Chemical agents have been used to prevent disease caused by this pathogenic fungus. However, their toxicity and reduced efficacy encouraged development new biological control alternatives. Recent studies shown that bacteria isolated from amphibian skin display antifungal activity against pathogens. mechanisms these act reduce effects B. are still unclear. From diverse collection bacteria, three...
Only quite recently, we have shown that yeast strains Clavispora lusitaniae 146 and Pichia fermentans 27 can act as efficient biocontrol agents for combating postharvest fungal diseases in lemons. During storage conditions, microorganisms are subject to different stress factors could affect both their survival protective capacity. Understanding the tolerance of yeasts environmental support future development commercial application biological control formulations based on such organisms....
Different strains of Micrococcus luteus, isolated from high-altitude Argentinean wetlands, were recently reported to harbour the linear plasmids pLMA1, pLMH5 and pLMV7, all which with 5′-covalently attached terminal proteins. The link between pLMA1 host’s erythromycin resistance as well further presumptive qualities prompted us perform a detailed characterization. When 454 technology was applied for direct sequencing gel-purified assembly reads impossible. However, combined Sanger/454 cloned...
