1
Dry host shoot biomass (Shoot) and root biomass (Root) are measured in grams (g) with standard error (se) from infections with ancestral (ancest.) and evolved (evolv.) cultures.
2
N, F and p values are given for a two-tailed ANOVA comparing relative growth effects and nodules formed from infections with ancestral (ancest.) and evolved (evolv.) cultures.
3
C refers to blocks of un-inoculated control plants which showed no significant variation in growth across blocks.
