A lower number of CFU per g was observed in the shoot tissues with both the bacteria 6. The vertical seed is orange to red-brown, with slightly papillose seed coat. A Bacterial isolates classification using the RDP classifier at genus level. Isolation and characterization of endophytic plant growth-promoting bacteria from date palm tree Phoenix dactylifera L. Together with Bacillusthe genus Pseudomonas was one of the two genera isolated using both the media and overall its abundance was higher in the supratidal rhizospheres.

The erect stems are cylindrical and succulent, with green joints that turn yellow as they age. Although subjected to the rhizosphere effect and thus showing a core pool of microbial isolates, S. Root colonization tests with selected strains proved that halophyte rhizospheric bacteria i stably colonize S.

Received Apr 28; Accepted Aug 4. Furthermore, the isolated strains have been screened in vitro for several PGP traits, including i production of IAA and ii siderophores, iii mineral phosphate solubilization, iv EPS and for tolerance to v abiotic stresses osmotic and temperature variation following the methods described strobikaceum Cherif et al.

Retrieved 8 August Under the tidal flow bacteria naturally associated to plant roots are subjected to periodical changes of selective pressures, on top of those constantly imposed by the sediment and root exudates.

The mostly bisexual flowers are somewhat immersed in the inflorescence axis. Marine microorganisms make a meal of oil. Perianth segments at fruit stage 3-lobed, unequal, dropform, broadly oblong, hyaline, apex truncate. Bacterial productivity and microbial biomass in tropical mangrove sediments. The gfp fluorescence is visible in green. The same strains incremented plant fresh and dry shoot biomass Figures 3B,C.


Support Center Support Center. Such uneven distribution of bacterial isolates could be explained by the different oxygen availability in the subtidal zone, strictly related to the strobolaceum pattern of root, from which oxygen can be lost storbilaceum a more suitable surrounding environment haloocnemum microbes Berg and Smalla, ; Oliveira et al. Phylogenetic affiliation of cultivable bacteria associated to the rhizosphere of Salicornia strobilacea grown under different tidal regimes.

Plant Biosystems 3, p. The plants are fleshy and halocnenum articulated with characteristic globular or short-cylindrical lateral branches, and reduced leaves and flowers. 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. It is native to coastal areas of the Mediterranean Sea and the Red Sea and parts of the Middle East and central Asia, where it grows in coastal strobilaaceum inland salt marshesalkali flatsand other habitats with saline soils.

EPS production was detected only when bacteria grew in absence of salt and it was present in a lower percentage of the isolates D Re-isolation experiments showing the ability of Pseudomonas strains SR and SR to actively halochemum both root and shoot tissues of S.

Cookies help us deliver our services. Similarly, dry weight increment has been detected in the root system for all the tested strains except SR Figures 3D—Fconfirming strlbilaceum the strains promoted plant growth. The network was constructed using Cytoscape version 3.

A gfp -labeled E.

Halocnemum strobilaceum – Flora of Qatar

The strains able to promote the growth were deriving from the rhizosphere of plants both from intertidal and supratidal zones indicating that S. Conceived and designed the experiments: The woody stems at the base are jointed and have sterile, rounded or conical shaped buds, arranged in whorls on the terminal part of each portion.

Genotypic responses of bacterial community structure to a mixture of wastewater-borne PAHs and PBDEs in constructed mangrove microcosms.


The induction of IAA production under salt condition was recently documented by Yaish et al. Most of the isolates from S. Abstract Halophytes classified under the common name of salicornia colonize salty and coastal environments across tidal inundation gradients. Biochar treatment resulted in a combined effect on soybean growth promotion and a shift in plant growth promoting rhizobacteria. Phylogenetic research confirmed, that Halocnemum is closely ualocnemum to the genus Halostachys.

Halophytes stgobilaceum under the common name of salicornia colonize salty and coastal environments across tidal inundation gradients. Critically revised the manuscript: All the data obtained demonstrated that plants growing across the tide regimes selected specific community at OTUs level.

Despite the different bacterial phylogenetic composition in the three tidal areas, the investigated phenotypic traits related to PGP potential did not significantly change according to our initial hypothesis.

Halocnemum strobilaceum – Wikispecies

The bacterial isolates were de-replicated by strain typing through ITS fingerprinting resulting in different haplotypes.

Gelatinous crusts of cyanobacteria sometimes form in depressions in the ground, and when these get dusted with windblown sand, H. To resolve the distribution of the isolate the profile network was used. 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.

Going back to the roots: The output peak matrix was transferred to Microsoft Excel for the following analysis. 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.
