Characterization of soils conducive and non-conducive to Prunus replant disease

Characterization of soil oomycete community relationships and composition among PRD-inducing and non-inducing soils.
(A) Non-metric multidimensional scaling (NMDS) ordination of soils based on Bray Curtis dissimilarity matrix (with overlays of hierarchical clustering at dissimilarity levels of 85% delimited by green lines and physicochemical vector relationships) and (B) hierarchical clustering of soils based on BC-dissimilarity and genus-level oomycete community composition of ITS1 amplicons. Soils are identified by number or by number and county-site, as in Table 1. The BC-dissimilarities were based on cumulative sum scaling (CSS) normalized, square root- transformed counts of oomycete ASVs identified from ITS1 region amplicons in different soils.
