Bacteria producing 1-aminocyclopropane-1-carboxylate (ACC) deaminase modulate plant ethylene levels. Decreased levels increase tolerance to environmental stresses and promote legume nodulation. On the contrary, role of in mycorrhizal symbiosis establishment is still controversial. In this work, ACC deaminase-producing strain Pseudomonas putida UW4 AcdS+ its mutant AcdS(-), impaired synthesis, were inoculated alone or combination with AM fungus Gigaspora rosea on cucumber. Mycorrhizal...
After the determination of toxic but nonlethal concentration NaCl for cucumber, we examined interaction between an ACC (1-aminocyclopropane-1-carboxylate) deaminase producing bacterial strain and arbuscular mycorrhizal fungus (AMF) their effects on cucumber growth under salinity.In first experiment, seedlings were exposed to 0.1, 50, 100 or 200 mmol l(-1) NaCl, plant biomass leaf area measured. While seeds did not germinate, size reduced by 50 salt. The latter salt cancentration caused death...
Arbuscular mycorrhizal fungi (AMF) colonize the roots of most terrestrial plant species, improving growth, nutrient uptake and biotic/abiotic stress resistance tolerance. Similarly, growth promoting bacteria (PGPB) enhance fitness production. In this study, three different AMF (Funneliformis mosseae, Septoglomus viscosum Rhizophagus irregularis) were used in combination with strains Pseudomonas sp. (19Fv1t, 5vm1K Pf4) to inoculate plantlets Fragaria x ananassa var. Eliana F1. The effects...
Candida albicans is an important opportunistic pathogen, responsible for the majority of yeast infections in humans. Essential oils, extracted from aromatic plants, are well‐known antimicrobial agents, characterized by a broad spectrum activities, including antifungal properties. The aim this work was to assess sensitivity 30 different vaginal isolated strains C. 12 essential compared three main used drugs (clotrimazole, fluconazole and itraconazole). Thirty were swab on CHROMagar™ Candida....
Summary The arbuscular mycorrhizal (AM) status of Solidago gigantea was investigated in a contaminated site Northern Italy, where the chemical industry ACNA (Associated National Chemical Companies) active till 1999. To counteract devastating effects chemicals and to allow re‐vegetation, soil from an uncontaminated area used cover highly polluted hills industrial about 25 years ago. On basis current floristic features, hill divided into four areas. Heavy metal content plant shoots roots...
Below ground and above plant-insect-microorganism interactions are complex regulate most of the developmental responses important crop plants such as tomato. We investigated influence root colonization by a nonmycorrhizal plant-growth-promoting fungus on direct indirect defenses tomato plant against aphids. The multitrophic system included Solanum lycopersicum ('San Marzano nano'), root-associated biocontrol Trichoderma longibrachiatum strain MK1, aphid Macrosiphum euphorbiae (a pest),...
Microorganisms associated with Vitis vinifera (grapevine) can affect its growth, health and grape quality. The aim of this study was to unravel the biodiversity bacterial rhizosphere microbiota grapevine in an integrated pest management vineyard located Piedmont, Italy. Comparison between microbial community structure bulk soil (variable: space) were performed. Moreover, possible shifts according two phenological stages such as flowering early fruit development time) characterized....
Phytoremediation is a promising green technique for the restoration of polluted environment, but there often gap between lab and field experiments. The fern, Pteris vittata L., can tolerate high soil arsenic concentration rapidly accumulate metalloid in its fronds. Arbuscular mycorrhizal fungi (AMF) are mutualistic that form symbiosis with most land plants’ roots, improve their growth, induce stress tolerance. This paper reports results obtained using P. inoculated AMF, to extract Arsenic...
Abstract Vitis vinifera L. is an economically important crop that can be influenced by soil microorganisms, including arbuscular mycorrhizal fungi (AMF), establish symbiotic associations with its roots. AMF have beneficial effects on grapevine performance improving water use efficiency and replant success. Most varieties are susceptible to various diseases, integrated pest management (IPM) one of the emerging approaches perform control. In present study, we examined communities in associated...
Antimicrobial resistance related to the misuse of antibiotics is a well-known current topic. Their excessive use in several fields has led enormous selective pressure on pathogenic and commensal bacteria, driving evolution antimicrobial genes with severe impacts human health. Among all possible strategies, viable one could be development medical features that employ essential oils (EOs), complex natural mixtures extracted from different plant organs, rich organic compounds showing, among...
The rhizosphere is a hotspot of microbial activity where the release root exudates stimulates bacterial density and diversity. majority cells in soil are viable, unculturable, but active. Proteomic tools could be useful gaining information about community to better understand real interactions between roots soil. aim this work was characterize associated with Vitis vinifera cv. Pinot Noir using metaproteome approach. Our results confirmed large potential proteomics describing environmental...
Flavescence dorée is an epidemic yellows disease of grapevine, caused by a phytoplasma (FDP), for which there currently no cure. We assessed whether the endophyte Pseudomonas migulae 8R6, able to synthesize 1-aminocyclopropane-1-carboxylate (ACC) deaminase, can limit phytoplasma-induced damages in periwinkle, model plant hosting FDP. Plant protection induced 8R6 and its mutant, impaired ACC deaminase synthesis, was compared. Fifteen plants per treatment were used; FD infection transmitted...
Abstract Maize is one of the most important crops worldwide and strongly dependent on arbuscular mycorrhiza (AM) fungi, organisms that form a mutualistic association with land plants. In maize, AM symbiosis enhances spike dry weight, length, circumference weight dimensions grain. Notwithstanding its ubiquitous nature, detailed relationship between fungal colonization plant development not completely understood. To facilitate better understanding effects fungi plants, work reported here...
