Ancient rapid radiation explains most conflicts among gene trees and well-supported phylogenomic trees of Nostocalean cyanobacteria
Prokaryotic genomes are often considered to be mosaics of genes that do not necessarily
share the same evolutionary history due to widespread horizontal gene transfers (HGTs) …
