Signature 1
Source: Table 1
Description: The top 10 differentially enriched genera from each kingdom and their preferred habitats. The estimates (coefficients) and P - values are from a generalized linear (Poisson) model, fit to determine the effect of the factor organ while taking into account differences in sequencing effort among samples. Note: the ‘Unassigned’ categories include diverse taxa, which themselves may be differentially enriched (or depleted) in the root relative to the leaf microbiome.
