Azospirillum Amazonense

Nitrogen-fixing bacteria were isolated from surface-sterilized seeds and roots of turf grasses growing in Nebraska. The percentage of successful isolations from surface-sterilized seeds ranged from 0 to 100 depending upon the source of the seeds. Based upon morphological and physiological characterization, some of the root and seed isolates appeared to be Azospirillum spp. Deoxyribonucleic acid homology studies on four selected isolates indicated that two root and one seed isolates were related to Azospirillum brasilense SP-7 with 70% or greater DNA homology, and one seed isolate was related to reference strain Azospirillum amazonense Y1 with 100% DNA homology. After repeated culturing on semisolid malate medium, some of the isolates lost their capacity to fix nitrogen. However, when certain non-nitrogen-fixing isolates were used as inoculants on turf grasses grown from surface-sterilized seeds which possessed no detectable indigenous nitrogen-fixing bacteria, nitrogenase activity as measured by acetylene reduction was detected.

Ten Streptomyces isolates from common scab lesions on carrots (Daucus carota) were characterized. Morphological and physiological characterization of the carrot isolates established that they were closely related to S. scabies. DNA-DNA hybridization studies were carried out between DNA from the carrot isolates and DNA from two potato strains belonging to the two genetic clusters of S. scabies. Most of the carrot isolates exhibited a high level of DNA relatedness (average of 90%) to strain EF-54, which belongs to genetic cluster 1 of S. scabies. Three carrot isolates could not be included in either S. scabies genetic cluster 1 or 2. The pathogenicity of six S. scabies isolates from potato or carrot, two isolates of S. caviscabies, and one isolate of S. acidiscabies was determined on potato, carrot, radish, beet, turnip, and parsnip. All S. scabies isolates were pathogenic on carrot and radish, but pathogenicity on beet, parsnip, turnip, and potato was variable. Even though S. acidiscabies and S. caviscabies until now have been isolated only from potato, we demonstrated that isolates of these species also could infect other crops, such as radish, carrot, parsnip, and turnip.
