A midpoint (·) indicates that the family was identified as key by the variable selection procedure and (***) indicates that the significance was at p < 0.001. Cells are colored depending on if the family is identified as key by (pink) both the multi-linear and clustering models, (yellow) the multi-linear model alone, (green) the clustering model alone, (blue) as negligible by both the multi-linear and clustering models, or (white) as not analyzed by the multi-linear model. The sign indicates the direction, positive (+) or negative (−), of the family’s contribution to SOM decomposition activity. For clustering analysis, the letter (A to F) indicates the most significant functional group to which a class of relative abundance of the family was assigned. Families were ranked from left to right in descending order of relative abundance.
