Despite intense research on genome architecture since the 2000s, genome-size evolution in prokaryotes has remained puzzling. Using a phylogenetic approach, a new study found that increased mutation rate is associated with gene loss and reduced genome size in prokaryotes.
尽管自 21 世纪初以来对基因组结构进行了深入研究，但原核生物的基因组大小演化仍然令人费解。一项新的研究使用系统发育方法发现，在原核生物中，突变率的增加与基因丢失和基因组大小的减少有关。
