Draft Genomes of Nitrogen-fixing Frankia Strains Ag45/Mut15 and AgPM24 Isolated from Root Nodules of Alnus Glutinosa.

ABSTRACT: The genomes of two nitrogen-fixing Frankia strains, Ag45/Mut15 and AgPM24, isolated from root nodules of Alnus glutinosa are described as representatives of a novel candidate species. Phylogenomic and ANI analyses confirmed that both strains are related to cluster 1 frankiae, and that both strains belong to a novel species. At 6.4 - 6.7 Mb, their genomes were smaller than those of other cultivated Alnus-infective cluster 1 strains but larger than that of the non-cultivated Alnus-infective cluster 1 Sp+ strain AgTrS that was their closest neighbor as assessed by ANI. Comparative genomic analyses identified genes essential for nitrogen-fixation, gene composition as regards COGs, secondary metabolites clusters and transcriptional regulators typical of those
