Re-isolation of the inoculated gfp -tagged strains from plant tissue confirmed the microscope observations. Besides contributing to the balance of carbon, nitrogen, and other elements in coastal ecosystems Kirchman et al.
Selection on soil microbiomes reveals reproducible impacts on plant function. Plant host habitat and root exudates shape soil bacterial community structure.
Rhizosphere effect and salinity competing to galocnemum microbial communities in Phragmites australis Cav. Halocnemum strobilaceum has small economic value as a grazing plant for camels and sheep. The diversity and biogeography of soil bacterial communities. The bacterial isolates were de-replicated by strain typing through ITS fingerprinting resulting in different haplotypes.
In this context, the ability to enrich and recruit PGP bacteria associated with salt-adapted plant is a promising research area to be further developed in upcoming years, and a key aspect for the selection novel PGP candidates Philippot et al. Journal List Front Microbiol v. Climate parameters are reported in the Supplementary Figure 2B.
Halophyte plant colonization as a driver of the composition of bacterial communities in salt marshes chronically exposed to oil hydrocarbons. The flowers are hermaphrodite and very small, and are arranged in whorls of three on the upper part of the branches. Root colonization tests with selected strains proved that halophyte rhizospheric bacteria i stably colonize S. Bacterial growth and tidal variation in bacterial abundance in the Great Sippewissett Salt Marsh.
Plant species and soil type cooperatively shape the structure and function of microbial communities in the rhizosphere.
Amaranthaceae from southern Turkey. National Center for Biotechnology InformationU.
Retrieved from ” https: Marinobacterfor example, was highly abundant in the subtidal and intertidal rhizospheres flooded by seawater. Among the toxic effects caused by high salinity, the reduction of nutrients availability i. However, little information is available on the role of tidal flooding regimes on determining the structure and diversity of plant-associated bacterial communities and their functional PGP potential.
Although total counts of cultivable bacteria did not change in the rhizosphere of plants grown along a tidal gradient, significant differences were observed in the diversity of both the cultivable and uncultivable bacterial communities. Despite the observed diversity in the bacterial community structure, the plant growth promoting PGP potential of cultivable rhizospheric bacteria, hxlocnemum through in vitro and in vivo tests, was equally distributed along the tidal gradient.
For instance, in mangrove ecosystems, exposure to tidal flow influences the microbial growth and biomass in intertidal surface sediments Alongi, The selected bacteria mainly showed effects on the plant promotion at the shoot level.
EPS production was detected only when bacteria grew in absence of salt and it was present in a lower percentage of the isolates Similar results were obtained by Borruso et al. This article was submitted to Plant Biotic Interactions, a section of the journal Frontiers in Microbiology.
Cluster analysis indicated that the supratidal rhizosphere cultivable bacterial community differed significantly from those collected in the subtidal and intertidal zones similarity Prokopos LagoonWestern AchaiaGreece. Conclusion The role of tidal regime on shaping the structure of rhizosphere bacterial communities has been demonstrated. Views Read Edit View history. Hughes A Directory of African Wetlandsp.
Isolation and characterization of endophytic plant growth-promoting bacteria from date palm tree Phoenix dactylifera L. The two selected strains belonged to the same genus but presented a different PGP potential both in vitro and in vivoconfirming the importance for the plant to interact with specific bacteria Panke-buisse et al. Furthermore, a correlation between the bacterial communities associated to S.

The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest. A gfp -labeled E. These genera have been already characterized in arid and saline ecosystems for their capacity to resist to multiple abiotic stresses, to grow in association with plant both with a rhizospheric and endophytic life-style and to exert PGP activities involved in the promotion and protection of plant growth Marasco et al.
The mostly bisexual flowers are somewhat immersed in the inflorescence axis. However the ability to tolerate the abiotic stresses, such as salinity, osmotic stress, and temperature variation, was widespread in the collection, confirming the adaptability of these strains to stressors typical of the environment of origin.
The phylogenetic affiliation of the 16S rRNA gene partial sequences and the network analysis on the dataset are reported in Figures 1A,Brespectively.
The area was subjected to a constant tidal flooding Supplementary Figure 2A with an excursion ranging from 20 cm during neap tide up to 1 m during spring tide. Several works demonstrated that bacteria are able to solubilize nutrients making them available for the bio-uptake Mapelli et al.
