Citrus production in Australia is a significant economic activity occurring in disparate regions. The crop is affected by a range of graft-transmissible pathogens including viroids, which are small, circular, non-coding RNA molecules. To ascertain the levels of infection with viroids in Australian citrus orchards, a survey was undertaken using samples collected between 2020 and 2024. To facilitate diagnosis, an RT-qPCR assay w...

Summary Members of the actinomycete genus Streptomyces are non‐motile, filamentous bacteria that are well‐known for the production of biomedically relevant secondary metabolites. While considered obligate aerobes, little is known about how these bacteria respond to periods of reduced oxygen availability in their natural habitats, which include soils and ocean sediments. Here, we provide evidence that the marine streptomycete s...
