Description
Tia Harrison and co-authors test if mutual aid between species speeds gene change across the whole genome. Their paper from 2024 compares legume plants that trade with root bacteria against kin that do not. Theory gives mixed calls for mutualism, unlike the clear speed up expected from hostile species pairs.
The team built gene read sets for twelve legume species and compared change rates at matched genes. Mutualist legumes showed higher genome wide change rates than non mutualists, though genes tied to the partnership itself did not follow the pattern. In bacteria, symbiotic types also showed higher rates than free living kin in most pairs. A third test inside one diverse bacterial genus gave a like result.
