When yeast cells meet, karyogamy!: an example of nuclear migration slowly resolved.
Gibeaux R, Knop M. Gibeaux R, et al. Nucleus. 2013 May-Jun;4(3):182-8. doi: 10.4161/nucl.25021. Epub 2013 May 15. Nucleus. 2013. PMID: 23715006 Free PMC article. Review.
Now, the molecular architectures of the underlying dynamic processes start to reveal their secrets. In yeast, karyogamy denotes the migration of two nuclei toward each other-termed nuclear congression-upon partner cell mating and the subsequent fusion of these nuclei to fo …

Karyogamy in rice zygotes: Actin filament-dependent migration of sperm nucleus, chromatin dynamics, and de novo gene expression.
Ohnishi Y, Okamoto T. Ohnishi Y, et al. Plant Signal Behav. 2015;10(2):e989021. doi: 10.4161/15592324.2014.989021. Plant Signal Behav. 2015. PMID: 25723729 Free PMC article.
Therefore, karyogamy is an important post-fusion event that bridges egg activation and de novo gene expression in fused gametes/zygotes. ...Then, 30-70 min after fusion, the sperm chromatin began to decondense, and karyogamy was completed. The development of early r …

The karyogamy gene KAR2 and novel proteins are required for ER-membrane fusion.
Latterich M, Schekman R. Latterich M, et al. Cell. 1994 Jul 15;78(1):87-98. doi: 10.1016/0092-8674(94)90575-4. Cell. 1994. PMID: 8033215
When cells containing distinctly tagged ER-nuclear envelope membranes are observed during mating, the markers of both parental membranes become colocalized in a process sharing a genetic requirement with karyogamy. Using isolated membranes, we find that fusion between ER c …

Karyogamy after Electrofusion of Single Egg and Sperm Cell Protoplasts from Maize: Cytological Evidence and Time Course.
Faure JE, Mogensen HL, Dumas C, Lorz H, Kranz E. Faure JE, et al. Plant Cell. 1993 Jul;5(7):747-755. doi: 10.1105/tpc.5.7.747. Plant Cell. 1993. PMID: 12271085 Free PMC article.
In maize, in vitro fusion of isolated male gametes with isolated egg cell protoplasts can be induced by electric pulses. Until now, karyogamy has not been demonstrated. In this study, we cytologically examined fusion products fixed at different times after electrofusion wi …

Sperm Entry into the Egg Cell Induces the Progression of Karyogamy in Rice Zygotes.
Ohnishi Y, Kokubu I, Kinoshita T, Okamoto T. Ohnishi Y, et al. Plant Cell Physiol. 2019 Aug 1;60(8):1656-1665. doi: 10.1093/pcp/pcz077. Plant Cell Physiol. 2019. PMID: 31076767
Karyogamy is a prerequisite event for plant embryogenesis, in which dynamic changes in nuclear architecture and the establishment of appropriate gene expression patterns must occur. ...Thus, the male sperm cell has the ability to cause immediate karyogamy and to est …

Dynamics of Male and Female Chromatin during Karyogamy in Rice Zygotes.
Ohnishi Y, Hoshino R, Okamoto T. Ohnishi Y, et al. Plant Physiol. 2014 Aug;165(4):1533-1543. doi: 10.1104/pp.114.236059. Epub 2014 Jun 19. Plant Physiol. 2014. PMID: 24948834 Free PMC article.
These gametes were fused in vitro to produce zygotes, and the nuclei and nuclear membranes in the zygotes were observed during karyogamy. The results indicated that the sperm nucleus migrates adjacent to the egg nucleus 5 to 10 min after plasmogamy via an actin cytoskelton …

Evidence for karyogamy and exchange of genetic material in the binucleate intestinal parasite Giardia intestinalis.
Poxleitner MK, Carpenter ML, Mancuso JJ, Wang CJ, Dawson SC, Cande WZ. Poxleitner MK, et al. Science. 2008 Mar 14;319(5869):1530-3. doi: 10.1126/science.1153752. Science. 2008. PMID: 18339940
Green fluorescent protein fusions of giardial homologs of meiosis-specific genes localized to the nuclei of cysts, but not the vegetative trophozoite. These data suggest that the fusion of nuclei, or karyogamy, and subsequently somatic homologous recombination facilitated …

Nuclear migration during karyogamy in rice zygotes is mediated by continuous convergence of actin meshwork toward the egg nucleus.
Ohnishi Y, Okamoto T. Ohnishi Y, et al. J Plant Res. 2017 Mar;130(2):339-348. doi: 10.1007/s10265-016-0892-2. Epub 2016 Dec 19. J Plant Res. 2017. PMID: 27995374
Fertilization is comprised of two sequential fusion processes; plasmogamy and karyogamy. Karyogamy completes with migration and fusion of the male and female nuclei in the fused cell. ...The velocity of the actin filaments was positively correlated with the velocity …
