Podosphaera fusca is the main causal agent of cucurbit powdery mildew in Spain. Four Bacillus subtilis strains, UMAF6614, UMAF6619, UMAF6639, and UMAF8561, with proven ability to suppress disease on melon detached leaf seedling assays, were subjected further analyses elucidate mode action involved their biocontrol performance. Cell-free supernatants showed antifungal activities very close those previously reported for vegetative cells. Identification three lipopeptide antibiotics, surfactin,...
This study was undertaken to isolate Bacillus subtilis strains with biological activity against soil-borne phytopathogenic fungi from the avocado rhizoplane.A collection of 905 bacterial isolates obtained rhizoplane healthy trees, contains 277 gram-positive isolates. From these isolates, four strains, PCL1605, PCL1608, PCL1610 and PCL1612, identified as B. subtilis, were selected on basis their antifungal diverse fungi. Analysis compounds involved in antagonistic showed that produced...
The practice of adding organic amendments to crop soils is undergoing resurgence as an efficient way restore soil matter content and improve quality. quantity quality the inputs affect physicochemical properties microbiota, influencing different parameters such microbial biomass diversity, community structure activities or functions. influence on has also effects production plant health. enhancement suppressiveness using been widely described, especially for soil-borne diseases. However,...
The antibacterial potential of four strains Bacillus subtilis, UMAF6614, UMAF6619, UMAF6639, and UMAF8561, previously selected on the basis their antifungal activity efficacy against cucurbit powdery mildew, was examined. Among these strains, UMAF6614 UMAF6639 showed highest in vitro, especially Xanthomonas campestris pv. cucurbitae Pectobacterium carotovorum subsp. carotovorum. These produced three families lipopeptide antibiotics known spp.: surfactins, iturins, fengycins. Using thin-layer...
Abstract Bacteria of the genera Pseudomonas and Bacillus can promote plant growth protect plants from pathogens. However, interactions between these plant-beneficial bacteria are understudied. Here, we explore interaction subtilis 3610 chlororaphis PCL1606. We show that extracellular matrix protects B. colonies infiltration by P. . The absence results in increased fluidity loss structure colony. type VI secretion system (T6SS) is activated upon contact with cells, stimulates sporulation....
A collection of 905 bacterial isolates from the rhizospheres healthy avocado trees was obtained and screened for antagonistic activity against Dematophora necatrix, cause root rot (also called white rot). set eight strains selected on basis growth inhibitory D. necatrix several other important soilborne phytopathogenic fungi. After typing these strains, they were classified as belonging to Pseudomonas chlororaphis, fluorescens, putida. The spp. analyzed their secretion hydrogen cyanide,...
Plant-beneficial Pseudomonas spp. competitively colonize the rhizosphere and display plant-growth promotion and/or disease-suppression activities. Some strains within P. fluorescens species complex produce phenazine derivatives, such as phenazine-1-carboxylic acid. These antimicrobial compounds are broadly inhibitory to numerous soil-dwelling plant pathogens play a role in ecological competence of phenazine-producing We assembled collection encompassing 63 representative worldwide diversity...
Abstract Application of external organic inputs to soils can be considered as one the most ancient strategies in agriculture, and it has been commonly used since very beginning human‐based agricultural practices. During all this time, application several matters demonstrated their benefit plants soils. Organic amendments have proved useful recovering soil properties, improving quality and, some cases, directly involved providing beneficial effects plants. All these obtained finally lead an...
An evaluation was made of the ability two mycoparasite‐based products AQ10® ( Ampelomyces quisqualis ) and Mycotal® Lecanicillium lecanii ), as well three strains Bacillus subtilis , to manage powdery mildew disease, caused by Podosphaera fusca on melon seedlings maintained under different regimes relative humidity plants grown greenhouse conditions in Spain. In every case fungal bacterial biocontrol agents (BCAs) performed better high (90–95% RH). experiments, effectiveness mycoparasites...
Summary Pseudomonas alcaligenes AVO73 and pseudoalcaligenes AVO110 were selected previously as efficient avocado root tip colonizers, displaying in vitro antagonism towards Rosellinia necatrix , causal agent of white rot. Despite the higher number antagonistic properties shown by AVO73, only demonstrated significant protection against As both strains are enhanced colonization is crucial for most likely biocontrol mechanisms used these strains, namely production non‐antibiotic antifungal...
Pseudomonas syringae is a phytopathogenic model bacterium that used worldwide to study plant-bacteria interactions and biofilm formation in association with plant host. Within this species, the pathovar most studied due its wide host range, affecting both, woody herbaceous plants. In particular, pv. (Pss) has been previously described as causal agent of bacterial apical necrosis on mango trees. Pss exhibits major epiphytic traits virulence factors improve survival pathogenicity The cellulose...
ABSTRACT Bacterial apical necrosis of mango, elicited by Pseudomonas syringae pv. syringae, limits fruit production in southern Spain and Portugal. Examination a collection P. isolates for copper resistance showed that 59% were resistant to cupric sulfate. The survey mango orchard revealed an increase frequencies copper-resistant bacteria after repeated treatments with Bordeaux mixture. These data suggest selection strains could be major reason control failures following management...
Nitrogen metabolism is one aspect of basic metabolism, which still quite unknown in the field plant–pathogen interactions. Evidence derived from previous studies conducted our laboratory strongly suggests that during microbial pathogenesis an important nitrogen mobilization process takes place diseased tissues. Here we describe expression pattern asparagine synthetase (AS; EC 6.3.5.4) tomato leaves infected by bacterial pathogen Pseudomonas syringae pv. tomato. Using homologous AS cDNA probe...
