Recombination is a common evolutionary tool for RNA viruses, and coronaviruses are no exception. We review here the evidence for recombination in SARS-CoV-2 and reconcile nomenclature for recombinants, discuss their origin and fitness, and speculate how recombinants could make a difference in the future of the COVID-19 pandemics.
重组是 RNA 病毒常见的进化工具,冠状病毒也不例外。本文回顾了 SARS-CoV-2 中重组的证据,调和了重组体的命名法,讨论了它们的起源和适应性,并推测了重组体在未来 COVID-19 大流行中可能会产生怎样的影响。
