Abstrakt
Common scab of potatoes (CS) is influenced by plant-microbe-soil interactions, which are locally specific. The study aims to identify any common trends in such interactions across a landscape differentiated by soil pH and CS severity.
Methods The 33 sites and 17 cultivars were characterized using soil and periderm nutrient contents and microbial communities. Quantitative PCR and Illumina amplicon sequencing were used to assess abundance of bacteria, actinobacteria and pathogens, and community composition.
