Background Nitrogen is an essential nutrient in plant growth. The ability of a plant to supply
all or part of its requirements from biological nitrogen fixation (BNF) thanks to interactions …

Agricultural practices contribute to climate change by releasing greenhouse gases such as
nitrous oxide that are mainly derived from nitrogen fertilizers. Therefore, understanding …

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 …

Phosphorus (P) and nitrogen (N) effects on nodulation, nitrogenase activity and plant growth
were studied in the root‐hair‐infected actinorhizal plant Alnus incana (L.) Moench. A split …

The aim of the present study was to evaluate phytohormone production by symbiotic and
saprophytic actinomycetes isolated from the actinorhizal plant Ochetophila trinervis which …

Actinomycetes from the genus Frankia induce nitrogen-fixing root nodules on actinorhizal
plants in the “core rosid” clade of eudicots. Reported here are nine partial Frankia 16S rRNA …

Background and Aims The present work aimed to study early stages of nodulation in a
chronological sequence and to study phosphorus and nitrogen effects on early stages of …

Nitrogen and phosphorus availability are frequent limiting factors in plant growth and
development. Certain bacteria and fungi form root endosymbiotic relationships with plants …

The influence of saprophytic actinomycetes strains on the Discaria trinervis–Frankia
actinorhizal symbiosis was investigated. Three strains out of 122 isolated from the …
