Author Contributions Conceived and designed the experiments: Interestingly, no Marinobacter was isolated from the supratidal S. The induction of IAA production under salt condition stdobilaceum recently documented by Yaish et al.
To resolve the distribution of the isolate the profile network was used. After this period, plantlets were gently harvest, washed, and transfer in pots containing ml of sterile marine water. Overall, these characteristics confer to the isolated strains all necessary adaptive traits to explicate their PGP activity in saline soils. The two gfp -labeled strains were halocnemym for colonization experiments on S.
Images were obtained with a Leica confocal microscope. This observation indicates that the tidal regime is contributing to the bacterial species selection in the rhizosphere.
In fruit the perianth remains unchanged. Such uneven distribution of bacterial isolates could be explained by the different oxygen availability in the subtidal zone, strictly related to the growth pattern of root, from which oxygen can be lost providing a more suitable surrounding environment for microbes Berg and Smalla, ; Oliveira et al.
The soil salinity in the selected area was determined in the field with a handheld multi-parameter system and ranged from Pollen grain 3-celled, penta-polyporate. Prokopos LagoonWestern AchaiaGreece. A cluster analysis performed by combining the bacterial PGP and abiotic stress tolerance traits grouped the strains in four clusters Supplementary Figure 7. Ovary superior with 2-awled stigma.
Biogeography of planktonic bacterial communities across the whole Mediterranean Sea. In the supratidal rhizosphere, Marinobacter and Alcanivorax were strlbilaceum by salt-loving bacteria of the genus Halomonaswhich have been previously observed in association with Salicornia spp. Plant species and soil type cooperatively shape the structure and function of microbial communities in the rhizosphere.
Cookies help us deliver our services. We moved beyond the consideration of the sole intertidal zone: The versatility in the root colonization, the overall PGP traits and the in vivo plant growth promotion under saline condition suggest that such beneficial activities likely take place naturally under a range of tidal regimes.
Biomass contribution is about 0. Druck, Grazp. Re-isolation of the inoculated gfp -tagged strains from plant tissue confirmed the microscope observations. This article was submitted to Plant Biotic Interactions, a section of the journal Frontiers in Microbiology.
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 the ability of selected rhizosphere bacterial types to actively recolonize S.
Several works demonstrated that bacteria are able to solubilize nutrients making them available for the bio-uptake Mapelli et al. Plant growth promoting traits and abiotic stresses tolerance of S. The main biostimulators identified in this study belong to the Pseudomonas and Bacillus genera. Isolation, characterization, and use for plant growth promotion under salt stress, of ACC deaminase-producing halotolerant bacteria derived from coastal soil.
Supplementary Material The Supplementary Material for this article can be found online at: The data were calculated as average of five plants per treatment and Student t -test was adopted to statistically analyze the data.
The network was constructed using Cytoscape version 3. The capacity of moving between different organs of the plant for instance from the root to the shoot should be further investigated to assess hakocnemum the bacteria move through the endosphere, the surface of the plant tissues or through aerosols from the rhizosphere. Halocnemum strobilaceum Scientific classification Kingdom: Perianth segments at fruit stage 3-lobed, unequal, dropform, broadly oblong, hyaline, apex truncate.
