New study pinpoints why some microbial genes are more promiscuous than others

A new study has identified the reason behind the variability in gene transfer among bacteria, revealing that genes involved in core cellular functions are less likely to be acquired. The study found that well-connected genes, which interact with many partners, are less likely to be transferred into a new host.
