study of some growth promotion properties of bacterial isolates from animal manures and identification of selected isolatesabstractbackground and objectives: plants growth in agricultural soils are affected by several biological factors. plant growth promoting bacteria can improve growth and yield of agronomic plants through direct and indirect mechanisms. minimizing consequences of using high ...

Bitki geli?imini te?vik eden bakterilerin (PGPB) alt grubu olan Endofit bakteriler (EB) bitki dokular? içinde de bulunabilmeleri nedeniyle hastal?klar? ile sava??mda önemli bir potansiyele sahiptir. Bu çal??mada dört farkl? endofit bakteri izolat?n?n domateste Clavibacter michiganensis subsp. (Cmm) patojeninin neden oldu?u bakteriyel kanser ve solgunluk hastal???n?n kontrolu? geli?imi u?zerine ...

Nitrogen-fixing bacteria have been isolated from sugarcane (Saccharum spp.) and other grasses in an endophytic and beneficial interaction that promotes plant growth. In this interaction, bacteria colonize the intercellular spaces and vascular tissues of most plant organs without causing disease symptoms. The best characterized sugarcane endophytic diazotrophs are Gluconacetobacter diazotrophicu...

background and objectives: nitrogen fixation is a biological process, which provides atmospheric nitrogen in usable form for plants, and satisfies the plants n requirement and can replace chemical fertilizers in high proportion. on the other hand, calcareous and high ph soils have usually small amounts of nutrients in available forms and use of plant growth promoting rhizobacteria can increase ...

One of the central the mechanisms used by many soil bacteria to directly promote plant growth is the production of the enzyme 1-aminocyclopropane-1-carboxylate (ACC) deaminase. This enzyme facilitates plant growth as a consequence of the fact that it sequesters and cleaves plantproduced ACC (the immediate precursor of ethylene in plants), thereby lowering the level of ethylene in the plant. In ...

21 In our study, we report the identification, characterization, and gene cloning of a novel 22 protein elicitor (PeBL1) secreted from Brevibacillus laterosporus strain A60. Through a 23 purification process consisting of ion exchange chromatography and HPLC, we isolated a 24 protein that was identified by ESI-QTOF-MS/MS. The 351-bp PeBL1 gene produces a 25 12833 Da protein with 116 amino acids...
