Fertilization alters protistan consumers and parasites in crop‐associated microbiomes

“…The assembly and stability of crop microbiomes are jointly influenced by a wide range of abiotic and biotic factors (Trivedi et al ., 2020). There is an increasing recognition that common agricultural management practices, such as organic and inorganic fertilizations, have significant effects on the dynamics, structure and functions of plant and soil microbiomes over time (Bonanomi et al ., 2018; Schmidt et al ., 2019; Zhao et al ., 2020). Soil protists are known to respond to changes in soil physicochemical conditions such as soil pore size, moisture content, pH and nutrients (Oliverio et al ., 2020; Zhao et al ., 2020).…”

Soil protists are known to respond to changes in soil physicochemical conditions such as soil pore size, moisture content, pH and nutrients (Oliverio et al ., 2020; Zhao et al ., 2020). Application of fertilizers, therefore, would impact the plant‐associated protistan communities through directly modifying soil properties or indirectly altering the communities of bacteria and fungi (Allison et al ., 2007; Álvarez‐Martín et al ., 2016) which can impact protists through the trophic food web interactions (Geisen et al ., 2018).…”

Plant Microbiota Beyond Farming Practices: A Review

“…Finally, no increase in (phyto)pathogenic bacteria was evidenced after irrigation with reclaimed water or piggery wastewater. Gu et al (2019) also evidenced a modulation of the spinach microbiome according to the quality of irrigation water. Although they did not find any increase in foodborne pathogens, they evidenced an increase in potential opportunistic (phyto)pathogens.…”

Concurrent and rapid recovery of bacteria and protist communities in Canadian boreal forest ecosystems following wildfire

“…However, at the early recovery stage, fire perturbations on the protist community may affect soil nutrient cycling, as protists enhance the microbial loop (i.e., releasing nutrients) and increase plant performance (e.g., plant pathogen protection) (Rosenberg et al, 2009). Protist communities are generally influenced by climatic factors (e.g., annual mean rainfall and temperature) (Oliverio et al, 2020), soil moisture, clay content and nutrient status (Zhao et al, 2019(Zhao et al, , 2020, but appear to be not overly sensitive to soil pH (Fiore-Donno et al, 2019). Our results showed that the effects of soil nutrient status, but not soil pH, on protist communities were reduced during the early stage after fire (Fig.…”
