Fitness effects of cross-species gene transfer in bacteria

Berenike Maier, U Cologne | web | email

Project A5 focuses on genome-wide evolution by lateral gene transfer across related Bacillus species. Massively parallel experiments map fitness effects governing the dynamics of gene transfer, including adaptive benefits and fitness barriers generated by functional mismatches between genes from different species in a single organism.
