Watter moulds, cried oomycetes bi scientists, are a smaa group o eukaryotic organisms. Wrangly kent as fungi afore, the watter moulds are kent tae be Protists in the Kinrick o Chromista nou. Thay are heterotrophic (thay aet ither organisms tae mak fuid) an thay mak mycelium. Thay differ fae fungi in thair structure, fer example oomycetes hae twa flagella while fungi hae juist wan (in Chytridiomycetes) or nae flagella in maist fungi. Oomycetes also haena chitin in thair cell waws, an haena septations except whiles atween cells in the sporangia.[4]

Disease[eedit | eedit soorce]

Rottit tattie infectit bi Phytophthora
A Tattie infectit wi Phytophthora Infestans, a plaunt pathogen.

Oomycetes are kent tae cause monie diseases. Phytophthora are a genus at cause sum o the maist rank blichts an diseases in plaunts. Notable diseases incluid late rot o tatties, at caused the Hieland Tattie Famine an the monie ither famines aroon Europe an aa.[5]

Resairchers are giein a bash at sortin oot thir diseases the nou, uisin fungicides an ither methods. Anither approach uised is tae mak the plaunt (tatties fer example) resistant tae the blichtenin oomycete organisms bi breedin resistant genes inti the plaunts.[6]
