Number of sequences from the guts and crops of pollen foragers showing 100% sequence similarity to the 13 putative crop-specific bacterial strains.

AStrain names according to [18]–[23].BRefers to the 4 clades depicted in Figure 4.CThe first column under each sample type represents the total number of reads from all 14 libraries having 100% sequence similarity to the queried strain. The second column shows the percent of the total sequence reads from that sample type matching the queried LAB strain sequence at 100%.DValue attained when comparing all trimmed sequences passing quality filtering, but classified at a confidence level
