Salicornia strobilacea (Synonym of Halocnemum strobilaceum) Grown under Different Tidal Regimes Selects Rhizosphere Bacteria Capable of Promoting Plant Growth.

摘要: Halophytes classified under the common name of salicornia colonize salty and coastal environments across tidal inundation gradients. To unravel role tide-related regimes on structure functionality root associated bacteria, rhizospheric soil Salicornia strobilacea (synonym Halocnemum strobilaceum) plants was studied in a zone coastline Southern Tunisia. Although total counts cultivable bacteria did not change rhizosphere grown along gradient, significant differences were observed diversity both uncultivable bacterial communities. This observation indicates that regime is contributing to species selection rhizosphere. Despite community structure, PGP potential assessed through vitro vivo tests, equally distributed gradient. Root colonization tests with selected strains proved halophyte (i) stably S. rhizoplane plant shoot suggesting they move from (ii) are capable improving growth. The versatility colonization, overall traits growth promotion saline condition suggest such beneficial activities likely take place naturally range regimes.
