Ukumba endaweni yezikhukhula (Buerenia inundata)
I-Floodplain drilling iyi-parasite yomndeni wakwa-Umbelliferae.
Isikhunta sitholakala kakhulu eNtshonalanga Yurophu. Ingatholakala naseziqhingini zaseBrithani, emuva eJalimane, eFrance naseSwitzerland. Isikhathi sokuqala sachazwa eFrance.
I-parasite ingathelela izinhlobo ezahlukene zesilimo esidliwayo esinamagatsha anamanzi, izaqathe kanye ne-marshmallow.
Umjikelezo wempilo wokumba we-floodplain wacwaningwa ngokuningiliziwe kuma-60-70s wekhulu leminyaka elidlule.
Amaseli e-ascogenous we-parasite agqekeza i-epidermis yesitshalo. Bakhululwa kanje. Asikho isikhathi sokuphumula. Abenzi futhi isinagoge. Usayizi wamaseli e-ascogenous akhulile ungafika ku-500 µm. Aqukethe cishe ama-nuclei angu-100-300. Bahlukanisa phakathi kwabo nge-meiosis, ngenxa yalokho kwakhiwa ama-ascopores e-mononuclear. Lezi zamuva zigxilwe onqenqemeni lweseli ye-ascogenous, futhi i-vacuole ithatha indawo phakathi nendawo.
I-parasite inama-ascopores. Ngaphambi kokumila, ziyazalana. Ama-ascopores atholakala ngezinhlobo ezimbili zokukhwelana ezibhekene (okubizwa ngokuthi i-bipolar heterothallism elula). Njengomphumela wokukhwelana, kwakheka iseli le-diploid, bese likhula libe yi-mycelium. Yile ndlela inqubo yokutheleleka kwesitshalo nokusatshalaliswa kwezikhala ze-intercellular yenzeka.
