Floodplain drilling (Buerenia inundata)
Floodplain drilling yog kab mob ntawm tsev neeg Umbelliferae.
Cov fungus feem ntau pom nyob rau hauv Western Europe. Nws tseem tuaj yeem pom nyob rau hauv cov Isles British, rov qab rau hauv lub teb chaws Yelemees, Fabkis thiab Switzerland. Thawj zaug nws tau piav nyob rau Fabkis.
Cov kab mob tuaj yeem kis tau ntau hom celery, carrots thiab marshmallow.
Lub neej voj voog ntawm dej nyab qhov av drilling tau kawm paub meej hauv 60-70s ntawm lub xyoo pua xeem.
Ascogenous hlwb ntawm cov kab mob parasite tawg los ntawm cov epidermis ntawm cov nroj tsuag. Qhov no yog li cas lawv thiaj li dim. Tsis muaj sijhawm so. Lawv kuj tsis tsim ib lub synascus. Qhov loj ntawm ascogenous hlwb loj hlob mus txog 500 µm. Lawv muaj txog 100-300 nuclei. Lawv faib ntawm lawv tus kheej los ntawm meiosis, raws li qhov tshwm sim ntawm cov mononuclear ascopores tsim. Cov tom kawg yog tsau rau ntawm lub periphery ntawm ascogenous cell, thiab lub vacuole yuav siv sij hawm qhov chaw nyob rau hauv qhov chaw.
Parasites muaj ascopores. Ua ntej germination, lawv sib yuav. Ascopores muaj nyob rau hauv ob hom mating uas yog qhov sib txawv rau ib leeg (lub thiaj li hu ua yooj yim bipolar heterothallism). Raws li ib tug tshwm sim ntawm mating, ib tug diploid cell yog tsim, uas ces hlob mus rau hauv mycelium. Qhov no yog li cas cov txheej txheem ntawm kev kis kab mob ntawm cov nroj tsuag thiab kev faib tawm los ntawm qhov chaw intercellular tshwm sim.
