Bacterial community composition of seed tuber and post-storage seed tuber samples. a Graphic representation of the sampling strategy. Seed tubers of 2 potato varieties (A and B) were harvested from 3 fields of production per variety and sampled for microbiome analysis before and after a 7-month cold storage period. PCoA of 16S amplicon sequencing data representing bacterial communities on b seed tubers of Variety A and B, c seed tubers of Variety A only, or d seed tubers of Variety B only, e post-storage seed tubers of Variety A and B, f post-storage seed tubers of Variety A only, and g post-storage seed tubers of Variety B only. Each symbol represents the bacterial community of one replicate potato peel sample. Each sample consists of a pool of potato peels collected from 6 seed tubers. For each variety, 4 replicate of seed tuber samples and 6 replicate of post-storage seed tuber samples were collected from each of the 3 fields of production. Green symbols represent Variety A and orange symbols represent Variety B. Different shapes within a same color represent distinct production fields. The P from PERMANOVA is shown in each PCoA plot. Each ellipse represents a 68% confidence region and depicts the spread of data points within each group
