Watter muilds, cried oomycetes bi scientists, is a smaa group o eukaryotic organisms. Wrangly kent as fungi afore, the watter muilds is kent tae be Protists in the Kinrick o Chromista nou. Thay are heterotrophic (thay aet ither organisms fur tae mak fuid) an thay mak mycelium. Thay differ fae fungi in thair structure, fer inxample oomycetes hae twa flagella while fungi haes juist wan (in Chytridiomycetes) or nae flagella in maist fungi. Oomycetes hisna 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 is kent tae cause muckle disease. Ane genus cried Phytophthora causes 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 in kintras aroon Europe causin the Revolutions o 1848 an aa.[5]

Resairchers is 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]
