Tuberosphere and bulk soil microbial communities in fields differing in common scab severity are distinguished by soil chemistry and interactions with pathogens

Original language description

Purpose 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. Results Comparisons between bulk and tuberosphere soil compartments as well as potato cultivars divided to three categories of CS susceptibility revealed that nitrogen was elevated in tuberosphere soil and N, Mg and Fe were lowered in periderm of resistant cultivars. The susceptible cultivar Agria grown at 7 sites had higher Ca content in tuberosphere soil, while the resistant cultivar Adela grown at 10 sites had higher S, P and Mg contents in its tuberosphere soil and P and Fe in periderm. That suggests further interactions between plants and bacterial community involving nutrient uptake. Diversity of bacteria was positively correlated with CS severity suggesting interactions between the Streptomyces pathogen populations and the local soil community. Conclusions Overall, pathogen abundance assessed by quantifying the thaxtomin biosynthetic txtB genes were randomly dispersed among the sites without connections to CS severity or soil pH. Thus, the significant differences between bacterial communities of bulk and tuberosphere soils together with cultivar CS susceptibility showed that the susceptible cultivars select bacterial community relatively similar to the bulk soil, while the resistant cultivars promote more distinct communities.
