Draft Genomes of Symbiotic Frankia Strains AgB32 and AgKG'84/4 from Root Nodules of Alnus Glutinosa growing under Contrasted Environmental Conditions.

ABSTRACT: The genomes of two nitrogen-fixing Frankia strains, AgB32 and AgKG'84/4, were isolated from spore-containing (spore+) and spore-free (spore-) root nodules of Alnus glutinosa, but they did not sporulate upon reinfection. The two strains are described as representatives of two novel candidate species. Phylogenomic and ANI analyses indicate that each strain represents a novel species within cluster 1, with genome sizes of 6.3 and 6.7 Mb smaller than or similar to those of other cultivated Alnus-infective cluster 1 strains. Genes essential for nitrogen-fixation, clusters of orthologous genes, secondary metabolite clusters and transcriptional regulators analyzed by comparative genomic analyses were typical of those from Alnus-infective cluster 1 cultivated str
