Microbiological analysis reveals diverse bacterial taxa shaped by climate and edaphic factors in Globodera rostochiensis cysts, suggesting nematode cysts serve as reservoirs of soil bacteria.

Key Points

To identify bacterial microbiota associated with potato cyst nematode populations, determine their phylogenetic relationships, and evaluate the effects of climatic and edaphic factors on bacterial diversity.
Isolated bacterial DNA from Globodera rostochiensis cysts collected from two potato fields and sequenced targeted 16S regions.
Constructed phylogenetic trees using maximum likelihood and Bayesian inference to classify isolated strains.
Evaluated the influence of local climate factors and soil organic matter content on bacterial community diversity.
Bacilli, Actinobacteria, and Alphaproteobacteria represented the predominant bacterial classes associated with the nematode cysts.
Phylogenetic analysis placed Brevibacterium frigoritolerans within the Bacillaceae family, supporting its recent taxonomic reclassification.
Bacterial diversity correlated with soil organic matter content and long-term climate variables, including temperature, insolation hours, humidity, and precipitation.
