| endophytic bacteria of mammillaria fraileana, an endemic rock-colonizing cactus of the southern sonoran desert. | the small cactus mammillaria fraileana is a pioneer rock-colonizing plant harboring endophytic bacteria with the potential for nitrogen fixation and rock weathering (phosphate solubilization and rock degradation). in seeds, only a combination of culture-independent methods, such as fluorescence in situ hybridization, scanning electron microscopy, and fluorescence vital staining, detected significant amounts of non-culturable, but living, endophytic bacteria distributed underneath the membrane co ... | 2011 | 21445557 |
