Protists are essential components of the rhizosphere microbiome, which is crucial for plant growth, but little known about relationship between growth and protists under salinity stress. Here we investigated wheat (Triticum aestivum L.) protistan communities naturally occurring (NOS) irrigation-reduced (IRS), linked a stress index (PSSI) to different groups in nontidal coastal saline soil. We found that PSSI was significantly correlated with cercozoan (including bacterivores, eukaryvores, omnivores) these were important predictors PSSI. Structural equation modeling suggested root exudation-induced change bacterial community composition affected bacterivorous omnivorous Cercozoa, associated across cultivars. Network analysis indicated more complex connections bacteria their predators IRS than NOS, implying alleviation promotes predation specific cercozoans on rhizospheres. Moreover, Cercomonas directa inoculation conducive Taken together, results suggest physiological response plants closely Cercozoa through trophic regulation within microbiome.
