Bacterial distribution in the rhizosphere of wild barley under contrasting microclimates.

<h4>Background</h4>All plants in nature harbor a diverse community of rhizosphere bacteria which can affect the plant growth. Our samples are isolated from the rhizosphere of wild barley Hordeum spontaneum at the Evolution Canyon ('EC'), Israel. The bacteria which have been liv...

Our samples are isolated from the rhizosphere of wild barley Hordeum spontaneum at the Evolution Canyon ('EC'), Israel. The bacteria which have been living in close relationship with the plant root under the stressful conditions over millennia are likely to have developed strategies to alleviate plant stress.<h4>Methodology/principal findings</h4>We studied distribution of culturable bacteria in the rhizosphere of H. spontaneum and characterized the bacterial 1-aminocyclopropane-1-carboxylate deaminase (ACCd) production, biofilm production, phosphorus solubilization and halophilic behavior. We have shown that the H. spontaneum rhizosphere at the stressful South Facing Slope (SFS) harbors significantly higher population of ACCd producing biofilm forming phosphorus solubilizing osmotic stress tolerant bacteria.<h4>Conclusions/significance</h4>The long-lived natural laboratory 'EC' facilitates the generation of theoretical testable and predictable models of biodiversity and genome evolution on the area of plant microbe interactions. It is likely that the bacteria isolated at the stressful SFS offer new opportunities for the biotechnological applications in our agro-ecological systems.Salme TimmuskViiu PaalmeTomas PavlicekJonas BergquistAmeraswar VangalaTriin DanilasEviatar NevoPublic Library of Science (PLoS)articleMedicineRScienceQENPLoS ONE, Vol 6, Iss 3, p e17968 (2011)
