Comparative Genomics Provides Insights into the Genetic Diversity and Evolution of the DPANN Superphylum

DPANN is known as highly diverse, globally widespread, and mostly ectosymbiotic archaeal superphylum. However, this group of archaea was overlooked for a long time, and there were limited in-depth studies reported. In this investigation, 41 metagenome-assembled genomes (MAGs) belonging to the DPANN superphylum were recovered (18 MAGs had average nucleotide identity [ANI] values of 50%, while 14 MAGs showed a POCP of
