Albuginaceae is a family of oomycetes.
Albuginaceae contains the following subtaxa: [1]
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, although the water-preferring nature which led to that name is not true of most species, which are terrestrial pathogens.
Leaf vegetables, also called leafy greens, pot herbs, vegetable greens, or simply greens, are plant leaves eaten as a vegetable, sometimes accompanied by tender petioles and shoots. Leaf vegetables eaten raw in a salad can be called salad greens.
Ulmus davidiana var. japonica, the Japanese elm, is one of the larger and more graceful Asiatic elms, endemic to much of continental northeast Asia and Japan, where it grows in swamp forest on young alluvial soils, although much of this habitat has now been lost to intensive rice cultivation.
Albugo candida, commonly known as white rust or white blister rust, is an obligate plant pathogen in the family Albuginaceae that infects Brassicaceae species. It has a relatively smaller genome than other oomycetes.
White rust may refer to:
Albugo ipomoeae-panduratae, or white rust, is an oomycete plant pathogen, although many discussions still treat it as a fungal organism. It causes leaf and stem lesions on various Ipomoea species, including cultivated morning glories and their relatives.
Albugo occidentalis, the causal agent of spinach white rust, is an oomycete plant pathogen, although some discussions still treat it as a fungal organism. Albugo occidentalis is one of the most important spinach diseases in North America, found throughout the United States east of the rocky mountains.
Pustula tragopogonis, the goatsbeard white rust, is an oomycete plant pathogen unrelated to fungal organisms.
Ipomoea indica is a species of flowering plant in the family Convolvulaceae, known by several common names, including blue morning glory, oceanblue morning glory, koali awa, and blue dawn flower. It bears heart-shaped or three-lobed leaves and purple or blue funnel-shaped flowers 6–8 cm (2–3 in) in diameter, from spring to autumn. The flowers produced by the plant are hermaphroditic. This plant has gained the Royal Horticultural Society's Award of Garden Merit.
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.
Cephalotaxus wilsoniana is a species of coniferous tree in the yew family, Taxaceae. Its common names include Taiwan plum yew, Taiwan cow's-tail pine, and Wilson plum yew. It is endemic to Taiwan, scattered in montane forests at altitudes of 1400-2700 meters. Cephalotaxus wilsoniana is mostly dioecious, because it's scattered with broad-leaved trees, the fecundity is not strong. In addition, the seed maturity period is very long. Germination and growth are also slow. Therefore, Cephalotaxus wilsoniana is not a common tree species in Taiwan.
Wilsoniana bliti, the white rust, is a type of oomycete pathogen of genus Wilsoniana that affects the tissues of plants. In particular, this white rust is found on Amaranth, beets and lambs quarters. Many discussions of this white rust treat it as a type of fungus.
Pseudotsuga sinensis is a species of conifer in the family Pinaceae. It is a tree up to 50 metres tall. It is found in China and Taiwan as well as in northernmost parts of Vietnam.
Schizura ipomoeae, the morning-glory prominent moth or false unicorn caterpillar, is a moth of the family Notodontidae. The species was first described by Edward Doubleday in 1841. It is found in the United States and southern Canada.
Albugo laibachii is a species of oomycete, whose genome has recently (2011) been sequenced. It is a plant pathogen of Arabidopsis thaliana. 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.
Syntomeida ipomoeae, the yellow-banded wasp moth or orange-banded wasp moth, is a moth in the subfamily Arctiinae. It was described by Thaddeus William Harris in 1839. It is found in the US states of Florida and Georgia.
Wilsoniana is a genus of plant-parasitic oomycetes segregated from Albugo. The name is in honor of the American mycologist G.W.Wilson
Pustula is a genus of plant-parasitic oomycetes segregated from Albugo. The name is derived from Latin's pustula meaning "blister".
Cornus wilsoniana, called ghost dogwood or Wilson's dogwood, is species of Cornus native to central and southeastern China. A tree typically 5 to 10 m, rarely reaching 40 m, it has leaves with white undersides, profuse white flowers in May, and striking grey–green mottled bark on mature specimens. The purplish‑black fruit are harvested for vegetable oil, the leaves are used for fodder, and the timber is valued for tools and furniture. Its well-shaped crown and attractive bark has led to proposals that it be developed as a street tree.
