Oomycetes, or water moulds, are fungal-like organisms phylogenetically related to algae. They cause devastating diseases in both plants and animals. Here, we describe seven oomycete species that are emerging or re-emerging threats to agriculture, horticulture, aquaculture and natural ecosystems. They include the plant pathogens Phytophthora infestans , Phytophthora palmivora , Phytophthora ramorum , Plasmopara obducens , and the animal pathogens Aphanomyces invadans , Saprolegnia parasitica and Halioticida noduliformans . For each species, we describe its pathology, importance and impact, discuss why it is an emerging threat and briefly review current research activities.
This article is part of the themed issue ‘Tackling emerging fungal threats to animal health, food security and ecosystem resilience’.
