The oomycete genus Lagenidium, which includes the mosquito biocontrol agent L. giganteum, is composed of animal pathogens, yet is phylogenetically closely related to the well characterized plant pathogens Phytophthora and Pythium spp. These phylogenetic affinities were further supported by the identification of canonical oomycete effectors in the L. giganteum transcriptome, and suggested, mirroring the endophytic abilities demonstrated in entomopathogenic fungi, that L. giganteum may have similarly retained capacities to establish interactions with plant tissues. To test this hypothesis, culture-independent, metabarcoding analyses aimed at detecting L. giganteum in bromeliad phytotelmata (a proven mosquito breeding ground) microbiomes were performed. Two …
