英文摘要	Finger millet is an important food crop that grows in arid and semi-arid parts of Africa and Asia and serve as a staple food source for millions of people. However, compared to other major crops, finger millet gives lower yield. For major crops high yield has been achieved through the introduction of improved varieties coupled with an intensive use of synthetic agrochemicals, often at the expense of the environment. In recent years endophytes received attention because of their potential to increase crop yield without massive application of synthetic chemicals. In this study seeds collected from three finger millet growing regions of Ethiopia contained a high load of bacterial endophytes. But no fungal endophytes were isolated from any of the samples. Based on their 16S rRNA gene sequence the isolates were identified as members of the genera Pantoea, Pseudomonas, Enterobacter, Sphingobacterium, Microbacterium, and Curtobacterium. A significant number of the isolates produced indole-3-acetic acid (IAA), were able to grow on nitrogen free medium, solubilized phosphate, and produced hydrogen cyanide. The most interesting observation was that the different genera showed restricted occurrence to a specific geographic location. Differences in plant growth promotion capacity based on the geographic location from which the isolates were obtained was also observed. Therefore, location specific differences in the distribution of the different taxonomic groups and their difference in plant growth promotion capacity could have important practical implication for the selection of the best microbial inoculants to improve plant growth and crop yield.
