Summary Although drought is an increasing problem in agriculture, the contribution of root‐associated bacterial microbiome to plant adaptation water stress poorly studied. We investigated if culturable associated with five grapevine rootstocks and cultivar Barbera may enhance growth under stress. Eight isolates, over 510 strains, were tested vivo for their capacity support The selected strains exhibited a vast array promoting ( PGP ) traits, confocal microscopy observation gfp ‐labelled A...
Summary Community‐level molecular techniques are widely used in comparative microbial ecology to assess the diversity of communities and their response changing environments. These include among others denaturing temperature gradient gel electrophoresis (DGGE/TGGE), single‐strand conformation polymorphism (SSCP), length heterogeneity‐PCR (LH‐PCR), terminal‐restriction fragment (tRFLP) 16S rRNA gene clone libraries. The amount data derived from these available literature is continuously...
ABSTRACT ITSF and ITSReub, constituting a new primer set designed for the amplification of 16S-23S rRNA intergenic transcribed spacers, have been compared with sets consisting 1406F 23Sr (M. M. Fisher E. W. Triplett, Appl. Environ. Microbiol. 65:4630-4636, 1999) S-D-Bact-1522-b-S-20 L-D-Bact-132-a-A-18 (L. Ranjard et al., 67:4479-4487, 2001), previously proposed automated ribosomal spacer analysis (ARISA) complex bacterial communities. An agricultural soil polluted soil, maize silage, goat...
Background Traditional agro-systems in arid areas are a bulwark for preserving soil stability and fertility, the sight of "reverse desertification". Nevertheless, impact desert farming practices on diversity abundance plant associated microbiome is poorly characterized, including its functional role supporting development under drought stress. Methodology/Principal Findings We assessed structure to drought-sensitive pepper (Capsicum annuum L.) cultivated traditional Egyptian farm, focusing...
Here, we show that an alpha-proteobacterium of the genus Asaia is stably associated with larvae and adults Anopheles stephensi, important mosquito vector Plasmodium vivax, a main malaria agent in Asia. bacteria dominate mosquito-associated microbiota, as shown by 16S rRNA gene abundance, quantitative PCR, transmission electron microscopy situ-hybridization genes. In adult mosquitoes, sp. present high population density female gut male reproductive tract. from An. stephensi has been cultured...
The plant compartments of Vitis vinifera, including the rhizosphere, rhizoplane, root endosphere, phyllosphere and carposphere, provide unique niches that drive specific bacterial microbiome associations. majority endophytes originate from soil migrate up to aerial through endosphere. Thus, endosphere partially define in leaves berries, contributing terroir fruit. However, V. vinifera cultivars are invariably grafted onto rootstocks other species hybrids. It has been hypothesized determines...
Abstract In the relentless battle for human health, proliferation of antibiotic‐resistant bacteria has emerged as an impending catastrophe unprecedented magnitude, potentially driving humanity towards brink unparalleled healthcare crisis. The unyielding advance antibiotic resistance looms foremost threat 21st century in clinical, agricultural and environmental arenas. Antibiotic is projected to be genesis next global pandemic, with grim estimations tens millions lives lost annually by 2050....
The rapid melting of mountain glaciers and the vanishing their streams is emblematic climate change1,2. Glacier-fed (GFSs) are cold, oligotrophic unstable ecosystems in which life dominated by microbial biofilms2,3. However, current knowledge on GFS microbiome scarce4,5, precluding an understanding its response to glacier shrinkage. Here, leveraging metabarcoding metagenomics, we provide a comprehensive survey bacteria benthic across 152 GFSs draining Earth's major ranges. We find that...
Deep hypersaline anoxic basins in the Mediterranean Sea are a legacy of dissolution ancient subterranean salt deposits from Miocene period. Our study revealed that these not biogeochemical dead ends, but support situ sulfate reduction, methanogenesis, and heterotrophic activity. A wide diversity prokaryotes was observed, including new, abundant, deeply branching order within Euryarchaeota . Furthermore, we demonstrated presence unique, metabolically active microbial community Discovery...
Abstract Background In recent years, acetic acid bacteria have been shown to be frequently associated with insects, but knowledge on their biological role in the arthropod host is limited. The discovery that of genus Asaia are a main component microbiota Anopheles stephensi makes this mosquito useful model for studies novel group symbionts. Here we present experimental results provide first evidence beneficial An. . Results Larvae at different stages were treated rifampicin, an antibiotic...
Since a few decades, apiculture is facing important economic losses worldwide with general major consequences in many areas of agriculture. A strong attention has been paid towards the phenomenon named Colony Collapse Disorder which colonies suddenly disappear no clear explanations. Honeybee can be affected by abiotic factors, such as environmental pollution or insecticide applications for agricultural purposes. Also biotic stresses cause colony losses, including bacterial (e.g....
Two-stage anaerobic digestion (AD) for integrated biohydrogen and biomethane production from organic materials has been reported to promise higher process efficiency energy recoveries as compared traditional one-stage AD. This work presents a comparison between two-stage (reactors R1 R2) (reactor R3) AD systems, fed with identical substrates loading rates, focusing the attention on chemical microbiological aspects. Contrary previous experiences, no significant differences in overall recovery...
Bacterial symbionts of insects have been proposed for blocking transmission vector-borne pathogens. However, in many vector models the ecology and their capability cross-colonizing different hosts, an important feature symbiotic control approach, is poorly known. Here we show that acetic acid bacterium Asaia, previously found malaria mosquito Anopheles stephensi, also present in, capable other sugar-feeding phylogenetically distant genera orders. PCR, real-time PCR situ hybridization...
Soil salinity and drought are among the environmental stresses that most severely affect plant growth production around world. In this study rhizospheres of Salicornia plants bulk soils were collected from Sebkhet Chott hypersaline ecosystems in Tunisia. Depiction bacterial microbiome composition by Denaturing Gradient Gel Electrophoresis unveiled occurrence a high diversity associated with root system. A large collection 475 halophilic halotolerant bacteria was established rhizosphere...
Seagrass meadows provide numerous ecosystem services and their rapid global loss may reduce human welfare as well ecological integrity. In common with the other 'blue carbon' habitats (mangroves tidal marshes) seagrasses are thought to coastal defence encourage sediment stabilisation surface elevation. A sophisticated understanding of elevation dynamics in mangroves marshes has been gained by monitoring a wide range different sites, located varying hydrogeomorphological conditions over long...
