occur. Karyogamy can occur within either mode of reproduction: during the sexual cycle or in somatic (non-reproductive) cells. Thus, karyogamy is the...
Fungus (redirect from Sexual reproduction in fungi)asci) is then formed, in which karyogamy (nuclear fusion) occurs. Asci are embedded in an ascocarp, or fruiting body. Karyogamy in the asci is followed...- Dioecy (redirect from Dioecious reproduction)female gametes, either directly (in animals) or indirectly (in seed plants). Dioecious reproduction is biparental reproduction. Dioecy has costs, since only...
Ascomycota (section Sexual reproduction in ascomycetes)meiosis. A similar sexual cycle is present in the red algae (Rhodophyta). A discarded hypothesis held that a second karyogamy event occurred in the ascogonium...- Sexual selection has been observed in fungi as a part of their reproduction, although they also often reproduce asexually. In the basidiomycetes, the...
Fertilisation (redirect from Fertilization in animals)fertilisation and development of new individuals is called sexual reproduction. During double fertilisation in angiosperms, the haploid male gamete combines with...- upregulate genes employed in responses to oxidative stress. The haploid nuclei of C. neoformans can undergo nuclear fusion (karyogamy) to become diploid. These...
Hexagonia vesparia (category Fungi described in 1839)Basidiomycota reproduce sexually and for germination to occur on the substrate, haploid spores of two different mating strains fuse (karyogamy),to produce dikaryotic...- after a dormant period of weeks to months, undergoes nuclear fusion (karyogamy) to produce a diploid nucleus. The diploid nucleus then undergoes meiosis...
- sporophores. Jahn was at first inclined to regard this union as the sexual karyogamy of the life-cycle, but the writer learns by correspondence (July 1910)
- time separation between plasmogamy and karyogamy. Phylum Zygomycota has (26) heterokaryotic state of reproduction limited to zygosporangium. Both Basidiomycota
