A PCoA ordination of the identified BGCs based on Bray–Curtis dissimilarity matrices. The amendment factor explained 81% of the differences observed in BGC composition between compost amended and non-amended pathogen-inoculated plants (Adonis test: pairwise permanova—amendment group R2 = 0.81, P < 0.05). B Family level taxonomic classification of Actinomycetota and Bacillota BGCs, highly abundant in the rhizosphere of compost amended FORC inoculated plants (MaAsLin2, coef > 2, P adj < 0.05). + indicates compost stimulated families that were also identified in 16S rRNA gene amplicon sequencing analysis. C BGC classes of compost protected bacterial families that were more abundant in compost-amended samples. Singleton BGCs were grouped as others
