Increased Expression of Maturation Promoting Factor Components Speeds Up Meiosis in Oocytes from Aged Females

The rate of chromosome segregation errors that emerge during meiosis I in the mammalian female germ line are known to increase with maternal age; however, little females (12 months old). Oocytes obtained from older fema...

CDC25A phosphatase controls meiosis I progression in mouse oocytes

a role of CDC25A in female meiosis. CDC25A cooperates together with CDC25B during resumption of meiosis, destruction of CDC25A in prometaphase I is crucial for MI-MII and translocates to the nucleus shortly before NEBD. CD...

Multiple sex chromosomes in the light of female meiotic drive in amniote vertebrates

to the different involvement of sex-specific sex chromosomes in female meiosis subjected to the female meiotic drive under male versus female heterogamety. Essentially, the male-specific Y chromosome is not involv...

Both male and female meiosis contribute to non-Mendelian inheritance of parental chromosomes in interspecific plant hybrids (Lolium × Festuca)

hybrids and reciprocal backcrosses to elucidate effects of male and female meiosis on the shift in parental genome composition. We studied male meiosis, including differently to the F2 generation. Female meios...

Accumulation of Securin on Spindle During Female Meiosis I

Chromosome segregation during female meiosis is frequently incorrect with severe consequences including termination of further development or severe disorders. We also compared the dynamics of securin proteolysis in meiosis...

Control of anaphase onset in mammalian female meiosis I

I have participated in a conference Study of Reproduction (SSR) 52nd Annual Meeting, Beyond Possible: Remarkable Transformation of Reproductive Biology v San Jose, California, USA, during July 18 – July 21, 2019. I took active part in form of a prese...

Asymmetrical canina meiosis is accompanied by the expansion of a pericentromeric satellite in non-recombining univalent chromosomes in the genus Rosa

(Rosa sect. Caninae) are capable of sexual reproduction due to their unique meiosis. During canina meiosis, two sets of chromosomes form bivalents and are transmitted by male and female gametes, whereas the remaining chrom...

High Penetrance of a Pan-Canina Type rDNA Family in Intersection Rosa Hybrids Suggests Strong Selection of Bivalent Chromosomes in the Section Caninae

All dogroses (Rosa sect. Caninae) are characterized by the peculiar canina meiosis in which genetic material is unevenly distributed between female and male as female parent (producing4x egg cells due to the unique asymmetr...
