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. These genera have been already characterized in arid and saline ecosystems for their capacity to resist to multiple abiotic stresses, halocnemym grow in association strobilacsum plant both with a rhizospheric and endophytic hzlocnemum and to exert PGP activities involved in the promotion and protection of plant growth Marasco et al.
Isolation halocnemm characterization of endophytic plant growth-promoting PGPB or stress homeostasis-regulating PSHB bacteria associated to the halophyte Prosopis strombulifera. Retrieved from ” https: Both Pseudomonas strains were recovered at high titres from the plantlets especially from the root, indicating that they actively grow in the rhizosphere.
Despite the different bacterial phylogenetic composition in the strobllaceum tidal areas, the investigated phenotypic traits related to PGP potential did not significantly change according to our initial hypothesis.
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.
Halophyte plant colonization as a driver of the composition of bacterial communities in salt marshes chronically exposed to oil hydrocarbons. Similarly, dry weight increment has been detected in the root system for all the tested strains except SR Figures 3D—Fconfirming that the strains promoted plant growth. No use, distribution or reproduction is permitted which does not comply with these terms.
Druck, Grazp. The roots of the halophyte Salicornia brachiata are a source of new halotolerant nalocnemum bacteria with plant growth-promoting potential. We are aware of the limitations of the cultivation-based approach for instance, we focused on the fast-growing bacteria that grow forming colonies after 72 h of incubation and we have not considered the slow growing bacteria.
Halocnemum strobilaceum – Flora of Qatar
The abiotic stress tolerance was equally distributed along the tidal gradient and was not driven by the presence of NaCl in the growth medium Figures 2A,B. After that period the biomass parameters were measured for five replicates per treatment. At successive times 48 and 96 hthe roots bacterized with gfp -labeled and the control strains were gently washed to remove the non-attached bacterial cells and analyzed by confocal laser-scanning microscopes Leica TCSNT with the Leica Confocal Software.
Mini-Tn7 transposons for site-specific tagging of bacteria with fluorescent proteins. From Wikipedia, the free encyclopedia. Frequently used in the rehabilitation or establishment of halophytic pastures. According to Bacchetta et al.
In strobilaceu projects Wikimedia Commons Wikispecies. However, we found that the distribution of the phylogenetic affiliation of bacteria isolated from S. In vitro antagonistic activity, plant growth promoting traits and phylogenetic affiliation of rhizobacteria associated with wild plants grown in arid soil.
The analysis take into account the abundance of each OTU in the samples. Marinobacter is a halophilic genus typically found in seawater and marine sediments McGenity et al.
Plant host habitat and root exudates shape soil bacterial community structure. No differences in term of total CFU per gram of rhizospheric sediment were observed in the three areas. Accessed 8 August We moved beyond the consideration of the sole intertidal zone: High-throughput deep sequencing reveals that microRNAs play important roles in salt tolerance of euhalophyte Salicornia europaea. Guide to Software and Statistical Methods. 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.
Hughes A Directory of African Wetlandsp.
Salicornia plants are common in many saline ecosystems, comprising dry salt lakes, lagoons, and strobilaceun areas where they are exposed to variable tidal regimes i. Rhizosphere bacteria help plants tolerate abiotic stress. Rhizocompetence and recolonization ability of S.
After this period, plantlets were gently harvest, washed, and strobilaaceum in pots containing ml of sterile marine water. Halophytes classified under the common name of salicornia colonize salty and coastal environments across tidal inundation gradients.
