Genetic exchange drives relatedness of large linear and circular extrachromosomal elements of archaea
Background Archaeal extra-chromosomal elements (ECEs) play key roles in archaeal host biology and evolution, yet little is known about their diversity and interactions with each other. Here, we report 42 complete 66 - 165 kbp genomes: 23 “Klingons”, 8 “Romulans” and “Romulan-like elements”, and 11 “Ferengi”, three new...
