Nyob rau hauv cov ntaub ntawv ntawm dormant spores nyob rau hauv eukaryotes, sporogenesis feem ntau tshwm sim li a tshwm sim ntawm fertilization los yog karyogamy tsim ib tug diploid spore sib npaug rau zygote. Yog li, zygospores yog qhov tshwm sim ntawm kev sib deev. Kev yug me nyuam ntawm spores cuam tshuam nrog kev sib kis ntawm cov spores los ntawm dej lossis cua.
Dab tsi ua rau sporogenesis tshwm sim hauv cov kab mob sib kis?
Sporulation yog cov lus teb hnyav ua los ntawm qee cov kab mob, feem ntau Firmicutes, teb rau kev ntxhov siab heev. Thaum lub sij hawm sporulation, lub cell loj hlob (tseem hu ua ib tug vegetative cell) yuav forego ib txwm cellular faib los ua ib tug endospore.
Lub hom phiaj tseem ceeb ntawm sporogenesis yog dab tsi?
Sporogenesis yog ib qho hloov kho uas tso cai rau cov hlwb kom muaj sia nyob hauv cov xwm txheej hnyav xws li hluav taws xob, qhov kub thiab txias, thiab tshuaj lom neeg.
Ntxhais ua rau sporulation yog dab tsi?
Qhov pib ntawm sporulation hauv Bacillus subtilis yog tshwm sim los ntawm a tsis muaj cov as-ham thiab los ntawm cov cell ceev(2, 15). Qhov kev txiav txim siab rau sporulate yog nruj nruj, vim tias cov txheej txheem siv zog siv zog ua haujlwm kawg rau cov hlwb tshaib plab.
Spore formation tshwm sim li cas?
Hauv cov nroj tsuag, spores feem ntau yog haploid thiab unicellular thiab yog tsim los ntawm meiosis hauv sporangium ntawm diploid sporophyte. Nyob rau hauv cov xwm txheej zoo, spore tuaj yeem loj hlob mus rau hauv ib qho tshiabkab mob siv mitotic division, tsim ib tug multicellular gametophyte, uas nws thiaj li mus rau tsim gametes.
