摘 要：Finding water resources for the desert plants is one of the important research areas since it enables saving water *** inermis plant was noticed to keep 5%of moisture in its rhizosphere zone;therefore,this study aimed to identify this source of *** endophytic bacteria were isolated from the root of *** and *** specific respiration rate was *** faecalis showed the highest specific respiration *** is a facultative chemoautotrophic hydrogen-fixing bacterium that utilizes the hydrogen gas as energy source and the water is produced as an end *** source of hydrogen gas for this bacterium is not only from air and soil gases but also from the hydrogen-producing bacteria such as Enterobacter spp.,which was among the isolated *** hydrogenases synthesizing genes(HoxC,HypA and HypB)were detected in most of the isolated bacteria and roots of four wild plants,out from 18 wild plant samples,epically the grains of the wild wheat *** result suggests that the hydrogen-fixing and hydrogen-producing bacteria transfer from the root through the plant to inhabit the grain/*** can help the grain/seeds to germinate in drought environment.
