These include diverse FCW-active shared patterns of gene expression across species.

We found 100 clusters containing developmentally NodB genes were developmentally regulated in all six species, regulated genes from all six species, and 196 in five species whereas, in the context of ectomycorrhizal symbioses, they were (Fig. 1D and Dataset S10).
