Microbial cross-feeding interactions reshape evolutionary trajectories of consumers by preserving motility.

This study shows that cross-feeding interactions influence consumer evolution by altering selective pressures on motility, with resource origin determining whether flagellar genes are lost or maintained.

Unilateral cross-feeding constrains adaptive evolution, even in the producer without direct fitness effects.

This study shows that unilateral cross-feeding interactions constrain adaptive evolution in both producer and consumer microbes, even when the producer experiences no direct fitness effects.
