Oomycete
The Oomycetes (), or Oomycota, form a distinct phylogenetic lineage of fungus-like eukaryotic microorganisms within the Stramenopiles. They are filamentous and heterotrophic, and can reproduce both sexually and asexually. Sexual reproduction of an oospore is the result of contact between hyphae of male antheridia and female oogonia; these spores can overwinter and are known as resting spores. Asexual reproduction involves the formation of chlamydospores and sporangia, producing motile zoospores. Oomycetes occupy both saprophytic and pathogenic lifestyles, and include some of the most notorious pathogens of plants, causing devastating diseases such as late blight of potato and sudden oak death. One oomycete, the mycoparasite '' Pythium oligandrum'', is used for biocontrol, attacking plant pathogenic fungi. The oomycetes are also often referred to as water molds (or water moulds), although the water-preferring nature which led to that name is not true of most species, whi ...

Albugo Candida
''Albugo candida'', commonly known as white rust or white blister rust, is an obligate plant pathogen in the family Albuginaceae that infects Brassicaceae species. (Although called a "rust" and a fungus, it is an oomycete.) It has a relatively smaller genome than other oomycetes. Distribution ''Albugo candida'' has a cosmopolitan distribution and is known from many countries where cruciferous crops are grown in Europe, Asia, Africa, Australasia, North, Central, and South America. It has not been recorded from northern Scandinavia, northern and central Siberia, northern China, western and central Africa, Alaska, northern and central Canada, and southern and western South America. Hosts This pathogen infects plants in the family Brassicaceae; the growth stages involved include the seedling stage, the growing stage, the flowering stage, and the fruiting stage. It has been recorded on almost all the varieties and species of the rapeseed-mustard group of crops as well as many wild br ...

Sunflower
The common sunflower (''Helianthus annuus'') is a species of large annual forb of the daisy family Asteraceae. The common sunflower is harvested for its edible oily seeds, which are often eaten as a snack food. They are also used in the production of cooking oil, as food for livestock, as bird food, and as plantings in domestic gardens for aesthetics. Wild plants are known for their multiple flower heads, whereas the domestic sunflower often possesses a single large flower head atop an unbranched stem. Description The plant has an erect rough-hairy stem, reaching typical heights of . The tallest sunflower on record achieved . Sunflower leaves are broad, coarsely toothed, rough and mostly alternate; those near the bottom are largest and commonly heart-shaped. Flower The plant flowers in summer. What is often called the " flower" of the sunflower is actually a "flower head" ( pseudanthium), wide, of numerous small individual five-petaled flowers (" florets"). The out ...

Albugo Evolvuli
''Albugo'' is a genus of plant-parasitic oomycetes. Those are not true fungi (Eumycota), although many discussions of this organism still treat it as a fungus. The taxonomy of this genus is incomplete, but several species are plant pathogens. ''Albugo'' is one of three genera currently described in the family Albuginaceae, the taxonomy of many species is still in flux. This organism causes white rust or white blister diseases in above-ground plant tissues. While these organisms affect many types of plants, the destructive aspect of infection is limited to a few agricultural crops, including: beets (garden and sugar), Brussels sprouts, cabbages, Chinese cabbage, cauliflower, collards, garden cress, kale, lettuce, mustards, parsnip, radish, horseradish, rapeseed, salsify (black or white), spinach, sweet potatoes, turnips, watercress, and perhaps water-spinach.

Albugo Laibachii
''Albugo laibachii'' is a species of oomycete, whose genome has recently (2011) been sequenced. It is a plant pathogen of ''Arabidopsis thaliana ''Arabidopsis thaliana'', the thale cress, mouse-ear cress or arabidopsis, is a small plant from the mustard family (Brassicaceae), native to Eurasia and Africa. Commonly found along the shoulders of roads and in disturbed land, it is generally ...''. ''Albugo laibachii'' also causes the host plant to become more susceptible to other parasites, when it normally would be more resistant, wearing down the host plant's immune system.
