Abstract

The genomes of two nitrogen-fixing Frankia strains, AiPa1 and AiPs1, are described as representatives of two novel candidate species. Both strains were isolated from root nodules of Alnus incana, used as capture plants in bioassays on soils from a reforested site at Karttula, Finland, that was devoid of actinorhizal plants but contained 25 year-old monocultures of spruce (Picea abies (L.) Karsten) or pine (Pinus sylvestris L.), respectively. ANI analyses indicate that each strain represents a novel Frankia species, with genome sizes of 6.98 and 7.35 Mb for AiPa1 and AiPs1, respectively. Both genomes harbored genes typical for many other symbiotic frankiae, including genes essential for nitrogen-fixation, for synthesis of hopanoid lipids and iron-sulfur clusters, as well as clusters of orthologous genes, secondary metabolite determinants and transcriptional regulators. Genomes of AiPa1 and AiPs1 had lost 475 and 112 genes, respectively, compared to those of other cultivated Alnus-infective strains with large genomes. Lost genes included one hup cluster in AiPa1 and the gvp cluster in AiPs1, suggesting that some genome erosion has started to occur in a different manner in the two strains.
