Albugo candida ( 加泰隆語 )

由wikipedia CA提供

Albugo candida és una espècie d'oomicet dins la família Albuginaceae; com altres oomicets és un fitopatogen. Com tots els oomicets no és pròpiament un fong, encara que de vegades es considera com si ho fos.

Albugo candida ( 英語 )

由wikipedia EN提供

Close up of Albugo candida on a mustard leaf

Albugo candida, commonly known as white rust, is a species of oomycete in the family Albuginaceae. It is sometimes called a fungus, but in fact forms part of a distinct lineage of fungus-like microorganisms, Oomycetes, commonly known as water moulds. A. candida is an obligate plant pathogen that infects Brassicaceae species and causes the disease known as white rust or white blister rust.[2] It has a relatively smaller genome than other oomycetes.[3]

Distribution

A. 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.[4]

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.[4] It has been recorded on almost all the varieties and species of the rapeseed-mustard group of crops as well as many wild brassicas. It has also been recorded on plants in the families Aizoaceae, Capparaceae, Cleomaceae, and Amaranthaceae. There are many different races and varieties of A. candida, each infecting its own group of species; for example, one infects Capsella, Arabis, and Lepidium, while another infects Brassica, Diplotaxis, and Sinapis.[5] Certain races of A. candida can colonise the model plant species, Arabidopsis thaliana. [6]

Symptoms

White rust can infect plants both locally and systemically. On stems, leaves, and inflorescences it appears as a mass of white or cream-coloured pustules, each about 2 mm (0.08 in) in diameter, packed with sporangia. New pustules are borne in radial fashion, while older pustules coalesce to form a bigger pustules in the center.[7] The systemic version causes distortion, abnormal growth forms, and sterile inflorescences. The abnormal growth forms are sometimes known as "stagheads".[8] Infection with white rust predisposes a crop to develop downy mildew, caused by another oomycete plant pathogen Phytophthora nicotianae.[9]

Life-cycle

When liberated, the sporangia inside the pustules are spread by wind, rain, and insects. After landing on a susceptible plant, each sporangium gives rise to about six zoospores which, under suitable conditions of moisture and light, form germ tubes which invade the plant's tissues. Zoospores are naked (wall-less), kidney-shaped and bi-flagellate. Both flagella are inserted laterally. Thick-walled sexual spores, called oospores are produced which germinate, producing either vesicles inside the plant tissue, exit tubes with vesicles at the tip, or germ tubes. Further zoospores develop inside the vesicles. The infection is spread by either oospore-infected seed or by mechanical movement of sporangia.[8]

Genome

Several projects have produced draft assemblies of A. candida. The most recent one, using Pacific Biosciences sequencing technology, produced an genome assembly of 38.96 megabases, with 13,073 predicted genes.[10] Amongst 1104 secreted proteins, 110 proteins belong to a class of effectors called "CCGs".

Albugo candida ( 西班牙、卡斯蒂利亞西班牙語 )

由wikipedia ES提供

Albugo candida es una especie de pseudohongo (Oomycetes) fitopatógeno perteneciente a la familia Albuginaceae. La enfermedad que causa este hongo en las plantas se denomina "roya blanca"

Hospedantes y enfermedades

  • Maíz: causa una enfermedad llamada Chahuixtle blanco. Se presenta todo el año causando su mayor daño durante la floración. El eje floral y las vainas se distorsionan, tuercen e hinchan durante la madurez adquiriendo un color blanco. En México se usa como expresión "Ya me cayó el Chauixtle" como metáfora referente a "Ya me arruiné" o "ya me atraparon".

Albugo candida ( 荷蘭、佛萊明語 )

由wikipedia NL提供

Witte roest (Albugo candida) is een oömyceet (waterschimmel), die behoort tot de familie Albuginaceae. Deze waterschimmel komt voor op planten die behoren tot de kruisbloemenfamilie, zoals het herderstasje en kool.

 src=
Albugo candida. 2= mycelium met haustoriën, 3=sporangium, 4 en 5 =zoösporevorming, 6=zoöspore, 7=oögonium (o) en antheridium (a), 8=oöspore, 9=kiemende oöspore en zoösporevorming, 10=zoöspore.

Op geïnfecteerde planten ontwikkelen zich ongeslachtelijke sporen (sporangia en zoösporen). Uit deze sporen kunnen nieuwe infecties ontstaan als de plant ten minste gedurende vier à acht uur nat blijft, de zogenaamde bladnat-periode. De geslachtelijke fase van de ziekte is met oösporen, die in tegenstelling tot de zoösporen gedurende een lange periode buiten de waardplant in leven blijven. Bij de paring van een hyfe van het type A1 met een hyfe van het type A2 worden een oögonium en een antheridium gevormd, waaruit de oöspore ontstaat. Deze eicel wordt binnen een gametangium door een spermatozoïde bevrucht. Uit de oösporen ontstaan sporangia en zoösporangia. De zoösporangia vormen ten slotte de zoösporen.
