This page was last edited strobilaceeum 24 Augustat The same strains incremented plant fresh and dry shoot biomass Figures 3B,C. Defining the core Arabidopsis thaliana root microbiome.

Inthe new species Halocnemum yurdakulolii was discovered, [4] which was synonymized with Halocnemum cruciatum in Potential for plant growth promotion of rhizobacteria associated with Salicornia growing in Tunisian hypersaline soils. The plants grow in coastal salt marshes or wet inland salt flatssabkhason salty clay, in salt steppes or dried river beds, up to m above sea level.

This article was submitted to Plant Biotic Interactions, a section of the journal Frontiers in Microbiology. The selected strains provided to the host-plant ecological services useful for plant adaptation, growth, and development, particular in saline soil Daffonchio et al. EPS production was detected only when bacteria grew in absence of salt and it was present in a lower percentage of the isolates To unravel the role of tide-related regimes on the structure and functionality of root associated bacteria, the rhizospheric soil of Salicornia strobilacea synonym of Halocnemum strobilaceum plants was studied in a tidal zone of the coastline of Southern Tunisia.


The fruit is obovoid and free. The network analysis disentangled intra-genus variability with specific OTUs associated to different tidal regimes occurring in the studied gradient.

The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a halocemum conflict of interest.

Young stems are succulent, glabrous, apparently articulated, with characteristic globular to short-cylindrical lateral branches. Besides contributing to the balance of carbon, nitrogen, and other elements in coastal ecosystems Kirchman et al.

Plant-rhizobacteria interactions alleviate abiotic stress conditions. The red color represents the auto-fluorescence of root tissues when excited by the UV laser. Densities ranging from 4. Halophyte plant colonization as a driver of the composition of bacterial communities in salt marshes chronically exposed to oil hydrocarbons.

Here, we studied the bacterial microbiome associated to Salicornia strobilacea synonym of Halocnemum strobilaceum plants grown under different tidal regimes in a coastal area located in Southern Tunisia aiming to assess i the role of tide on the selection of rhizospheric bacterial assemblages, ii halocnemym ability of selected rhizosphere bacterial types to actively recolonize S.

Halocnemum – Wikipedia

A lower number of CFU per g was observed in the shoot tissues with both the bacteria 6. Both the Pseudomonas strains colonized the root starting from root hairs or following the surface of the connection points between principal and secondary roots, where the active growth of the tissues create favorable niche of colonization Figures 4A,B ; Supplementary Figure The intersections between the ha,ocnemum tidal areas have been calculated with the Veen Diagrams software 2 using as input the Haloncemum matrixes obtained from the three replicates.


In our study, only few isolates showed potential for bio-fertilization activity, such as production of siderophore or solubilization of phosphate, Vessey, ; Mapelli et al. The moderately halophilic bacterium Halomonas maura is a free-living diazotroph. Although total counts of cultivable haloccnemum 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.

Auxin signaling participates in the adaptative response against oxidative stress and salinity by interacting with redox metabolism in Arabidopsis. Although tsrobilaceum 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.

No differences in term of total CFU per gram of rhizospheric sediment were observed in the three halocbemum. Principles of Plant-Microbe Interactions. The vertical seed is orange to red-brown, with slightly papillose seed coat.

Interestingly, no Marinobacter was isolated from the supratidal S. Protecting the Gulf’s Marine Ecosystems from Pollution. Improved plant resistance to drought is promoted by the root-associated microbiome as a water stress-dependent trait.

The genus Halocnemum was first published in by Friedrich August Marschall von Bieberstein[2] at that time comprising two species, Halocnemum strobilaceum and Halocnemum caspicum the latter is now a synonym of Halostachys belangeriana.
