Genetic diversity and symbiotic compatibility among rhizobial strains and Desmodium incanum and Lotus spp. plants
This work aimed to evaluate the symbiotic compatibility and nodulation efficiency of rhizobia isolated from Desmodium incanum, Lotus corniculatus, L. subbiflorus, L. uliginosus and L. glaber plants by cross-inoculation. Twelve reference strains and 21 native isolates of rhizobia were genetically analyzed by the BOX-PCR technique, which showed a high genetic diversity among the rhizobia studied....
متن کاملNAD1 Controls Defense-Like Responses in Medicago truncatula Symbiotic Nitrogen Fixing Nodules Following Rhizobial Colonization in a BacA-Independent Manner
Legumes form endosymbiotic interaction with host compatible rhizobia, resulting in the development of nitrogen-fixing root nodules. Within symbiotic nodules, rhizobia are intracellularly accommodated in plant-derived membrane compartments, termed symbiosomes. In mature nodule, the massively colonized cells tolerate the existence of rhizobia without manifestation of visible defense responses, in...
متن کاملPermanent draft genome sequences of the symbiotic nitrogen fixing Ensifer meliloti strains BO21CC and AK58
Ensifer (syn. Sinorhizobium) meliloti is an important symbiotic bacterial species that fixes nitrogen. Strains BO21CC and AK58 were previously investigated for their substrate utilization and their plant-growth promoting abilities showing interesting features. Here, we describe the complete genome sequence and annotation of these strains. BO21CC and AK58 genomes are 6,985,065 and 6,974,333 bp l...
متن کاملCorals form characteristic associations with symbiotic nitrogen-fixing bacteria.
The complex symbiotic relationship between corals and their dinoflagellate partner Symbiodinium is believed to be sustained through close associations with mutualistic bacterial communities, though little is known about coral associations with bacterial groups able to fix nitrogen (diazotrophs). In this study, we investigated the diversity of diazotrophic bacterial communities associated with t...
متن کاملStudies of aerobic non-symbiotic nitrogen-fixing bacteria.
The occurrence of aerobic, non-symbiotic, nitroqen-fixing bacteria was determined in samples of soil collecte~l in the various soil zones of Allxrm and Saslcatchewan. Mannitol and sodiuttl betuoate dust-platrs. and mallnit01 solution cultures wiLh subsequent inoculation onto rnannitol agar demonstrated that Asolohnrtt-r were not wirlcspreatl in the Canadian prairie province soils. These r)n)ccr...
