In this study, we provide experimental evidence for both of these predictions in the mutualism between the legume Amphicarpaea bracteata and its nitrogen-fixing root nodule bacteria (Bradyrhizobium sp.).
Amphicarpaea bracteata is an annual plant indigenous to eastern North America (Turner and Fearing 1964).

The current study used the annual legume Amphicarpaea
bracteata and its associated root nodule bacteria (genus Bradyrhizobium) to investigate this issue.

Plants that rely on selfing as a large component of their reproduction (e.g., Impatiens: Schemske 1984; Schmitt and Gamble 1990; Amphicarpaea
: Parker 1991; Danthonia: Clay 1991) may continue to be vulnerable to herbivore and pathogen enemies adapted to the parental genotype despite recombination.
Herbaceous plants found in the meadow were Agrimonia parviflora, Amphicarpaea
bracteata, Asclepias incarnata, Boehmeria cylindrica, Cardamine bulbosa, Cuscuta gronovii, Eupatorium perfoliatum, Impatiens spp., Lobelia siphilitica, Lycopus americanus, Mentha arvensis, Pilea pumila, Polygonum spp., Rudbeckia laciniata, Solidago patula, Stachys nuttallii, and Veronica anagallis-aquatica.
