More than 200 angiosperms, distributed in 25 genera, develop root nodule symbioses
(actinorhizas) with soil bacteria of the actinomycetous genus Frankia. Although most soils …

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 …

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 …

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

The actinorhizal plants that are nodulated by the symbiotic, N2-fixing actinomycete Frankia
include 25 genera in 8 families of angiospermous plants (Table 1). Actinorhizal plant …

The Biology of Frankia and Actinorhizal Plants provides a comprehensive review of Frankia
and the actinorhizal plants. It reviews the state of knowledge on all aspects from molecular …

The genus Frankia is at present the sole genus in the family Frankiaceae and encompasses
filamentous, sporangia-forming actinomycetes principally isolated from root nodules of …

We compiled quantitative estimates on symbiotic N 2 fixation by trees in agroforestry
systems (AFS) in order to evaluate the critical environmental and management factors that …

We studied the potential of the humus layer of the Norway spruce stands to supply beneficial
rhizobacteria to birch (Betula pendula), alder (Alnus incana) and fescue grass (Festuca …
