Range

Hyaloperonospora berteroae is a host-specific downy mildew oomycete in the family Peronosporaceae that parasitizes Berteroa species, small white-flowered plants in the mustard family (Brassicaceae). It forms colorless sporangiophores that emerge from stomata to produce spores, causing pale patches on infected leaves. Like other downy mildew pathogens, it is an obligate biotroph that cannot survive without a living host.

koala

Iconic marsupial of eastern and southeastern Australia, koalas weigh up to 15 kg and spend up to 22 hours daily sleeping to conserve energy from their low-calorie eucalyptus leaf diet. Highly specialized to process toxic eucalyptus compounds that would kill most other mammals, they have gut microbiomes uniquely adapted for detoxification. Listed as Endangered in 2022, with populations decimated by chlamydia disease, habitat clearing, and climate change.
