The majority of the most economically important plant and crop species are enriched with
the availability of high-quality reference genome sequences forming the basis of gene …

Plants associate with nitrogen-fixing bacteria to secure nitrogen, which is generally the most
limiting nutrient for plant growth. Endosymbiotic nitrogen-fixing associations are widespread …

Root nodules formed by plants of the nitrogen-fixing clade (NFC) are symbiotic organs that
function in the maintenance and metabolic integration of large populations of nitrogen-fixing …

Legumes and actinorhizal plants are capable of forming root nodules symbiosis with
rhizobia and Frankia bacteria. All these nodulating species belong to the nitrogen fixation …

Frankia strains are nitrogen-fixing soil actinobacteria that can form root symbioses with
actinorhizal plants. Phylogenetically, symbiotic frankiae can be divided into three clusters …

In the late 19 th century, it was discovered that legumes can establish a root nodule
endosymbiosis with nitrogen-fixing rhizobia. Soon after, the question was raised whether it is …

The transcript pool of a plant part, under any given condition, is a collection of mRNAs that
will pave the way for a biochemical reaction of the plant to stimuli. Over the past decades …

Nodules of legume plants are highly integrated symbiotic systems shaped by millions of
years of evolution. They harbor nitrogen-fixing rhizobium bacteria called bacteroids. Several …

Highlights•Actinorhizal plants associate with Frankia to form nitrogen-fixing

Root nodule symbioses (RNS) allow plants to acquire atmospheric nitrogen by establishing
an intimate relationship with either rhizobia, the symbionts of legumes or Frankia in the case …
