Symbiotic association of the N 2-fixing actinomycete Frankia with the roots of more than 200
tree species from 24 genera of 8 families of angiosperms has been studied since 1829. The …

Molecular phylogenetic approaches have begun to outline the origin, distribution and
diversity of actinorhizal partners. Geographic isolation of Frankia and its host plants resulting …

Many rhizospheric bacterial strains possess plant growth-promoting mechanisms. These
bacteria can be applied as biofertilizers in agriculture and forestry, enhancing crop yields …

A bstract The term``actinorhiza''refers both to the filamentous bacteria Frankia, an
actinomycete, and to the root location of nitrogen-fixing nodules. Actinorhizal plants are …

Frankia is a genus of soil actinomycetes famous for its ability to form N 2-fixing root nodule
symbioses with actinorhizal plants. Although Frankia strains display a high diversity in terms …

Based on partial 16S sequences, we previously described a novel group of nonsymbiotic,
acetylene reduction activity-positive actinomycetes which were isolated from surface …

Background The ability to establish root nodule symbioses is restricted to four different plant
orders. Soil actinobacteria of the genus Frankia can establish a symbiotic relationship with a …

La fijación biológica del nitrógeno (diazotrofía) es un proceso muy antiguo que
probablemente se originó en el Eon arqueano bajo las condiciones anoxigénicas de la …

Frankia strains induce the formation of nitrogen-fixing nodules on roots of actinorhizal plants.
Phylogenetically, Frankia strains can be grouped in four clusters. The earliest divergent …

Injera is soft fermented baked product, which is commonly prepared from teff (Eragrostis tef
(Zucc.)) flour and believed to be consumed on daily basis by two‐thirds of Ethiopians. As it is …
