Rapid functional activation of horizontally transferred eukaryotic intron-containing genes in the bacterial recipient.

ABSTRACT: Horizontal gene transfer has occurred across all domains of life and contributed substantially to the evolution of both prokaryotes and eukaryotes. Previous studies suggest that many horizontally transferred eukaryotic genes conferred selective advantages to bacterial recipients, but how these eukaryotic genes evolved into functional bacterial genes remained unclear, particularly how bacteria overcome the expressional barrier posed by eukaryotic introns. Here, we first confirmed that the presence of intron would inactivate the horizontally transferred gene in Escherichia coli even if this gene could be efficiently transcribed. Subsequent large-scale genetic screens for activation of gene function revealed that activation events could rapidly occur within several days of selective cultivati
