Biocontrol-relevant diversity of wheat-associated <i>Pseudomonas</i>: prevalence of <i>P. sivasensis</i> and identification of the novel species <i>P. arvensis</i> sp. nov.

ABSTRACT: The role of microbial communities in plant health and productivity has become increasingly evident. In this study, we investigated the diversity and functional potential of Pseudomonas spp. associated with Belgian cereal crops, focusing on wheat and spelt. From 444 Pseudomonas isolates, we identified 11 species, with several strains exhibiting strong antagonistic activity against major wheat pathogens. Notably, we report the high prevalence and efficient colonization abilities of Pseudomonas sivasensis, including its capacity to translocate from seed to leaf and suppress Zymoseptoria tritici infection in planta. Furthermore, we describe Pseudomonas arvensis sp. nov., a newly characterized species within the wheat microbiome, with DR1PS3 designated
