Arbuscular mycorrhiza(a type of mycorrhiza in which the symbiont fungus penetrates the cortical cells of the roots of a vascular plant forming arbuscules) fungi from the Glomeraceae family yielded the most MOTUs accross all the primers.
An arbuscular mycorrhiza (plural mycorrhizae, a.k.a. endomycorrhiza) is a type of mycorrhiza in which the symbiont fungus (AM fungi, or AMF) penetrates the cortical cells of the roots of a vascular plant forming arbuscules.

This may be explained by the ability of the "Redecker" primers to find less abundant AMF lineages such as the Claroideoglomeraceae or the Paraglomeraceae LSU primers had a strong bias towards Glomeraceae, excluding other families SSU primers had a bias towards Glomeraceae and underestimated the presence of different families within the Glomeromycota, including the Claroideoglomeraceae, Diversisporaceae and Paraglomeraceae
