Horizontal gene transfer and spreading of biosynthetic gene clusters and antimicrobial resistance
Biosynthetic gene clusters (BGCs) for natural products are widespread in microbial genomes, and they are rapidly exchanged. This research assesses the factors that control the spread of BGCs and resistance genes in nature. This includes risk assessment for the spread of engineered DNA in nature.
