Predatory protists reduce bacteria wilt
disease incidence in tomato plants
Soil organisms are affected by the presence of predatory protists. However, it
remains poorly understood how predatory protists can affect plant disease
incidence and how fertilization regimes can affect these interactions. In a newly
published research, the researchers characterize the rhizosphere bacteria, fungi, and
protists over eleven growing seasons of tomato planting under three fertilization
regimes, i.e. conventional, organic, and bioorganic, and with different bacterial wilt
disease incidence levels. The study provides insights into the role that predatory
protists play in plant disease, which could be used to design more sustainable
agricultural practices.
"We find that predatory protists are negatively associated with disease incidence,
especially two ciliophoran Colpoda OTUs, and that bioorganic fertilization enhances
the abundance of predatory protists", they share. "In glasshouse experiments, we
find that the predatory protist Colpoda influences disease incidence by directly
