Interspecific somatic hybrids between Solanum bulbocastanum and S. tuberosum and their haploidization for potato breeding. [PDF]
, 2012 Protoplast fusion between incongruent Solanum bulbocastanum and S. tuberosum haploids was accomplished to produce hybrids combining elite traits from both parents. We identified 11 somatic hybrids out of 42 regenerants analyzed through ISSR markers. Some

Four Loci on Abnormal Chromosome 10 Contribute to Meiotic Drive in Maize [PDF]
Genetics, 2003 Abstract We provide a genetic analysis of the meiotic drive system on maize abnormal chromosome 10 (Ab10) that causes preferential segregation of specific chromosomal regions to the reproductive megaspore. The data indicate that at least four chromosomal regions contribute to meiotic drive, each providing distinct functions that can be ...

Conditional inactivation of the DNA damage response gene Hus1 in mouse testis reveals separable roles for components of the RAD9-RAD1-HUS1 complex in meiotic chromosome maintenance. [PDF]
PLoS Genetics, 2013 The RAD9-RAD1-HUS1 (9-1-1) complex is a heterotrimeric PCNA-like clamp that responds to DNA damage in somatic cells by promoting DNA repair as well as ATR-dependent DNA damage checkpoint signaling.

Frontiers in Cell and Developmental Biology, 2021 Mitochondrial division inhibitor 1 (Mdivi-1) reportedly provides a close connection between oocyte maturation and mitochondrial function in pigs. N-acetyl-5-methoxy-tryptamine (melatonin) is known to be a representative antioxidant with the ability to ...

DNA double strand breaks but not interstrand crosslinks prevent progress through meiosis in fully grown mouse oocytes [PDF]
, 2012 There is some interest in how mammalian oocytes respond to different types of DNA damage because of the increasing expectation of fertility preservation in women undergoing chemotherapy.

Molecular Oncology, EarlyView.EXOSC10, an essential nuclear RNA exosome‐associated 3′‐5′ exoribonuclease, is inhibited by the anticancer drug 5‐fluorouracil (5‐FU), and EXOSC10 depletion increases 5‐FU sensitivity. The colon‐cancer variant EXOSC10S402T, located in a proteolysis motif, is stable and nuclear but nonfunctional in vivo.

Roles of Meiotic Defects in Pathogenesis of Primary Ovarian Insufficiency
Reproductive and Developmental Medicine, 2017 A matured oocyte has experienced three critical division stages: (1) proliferation in early fetal stage, (2) meiotic arrest at diplotene of prophase I, and (3) meiotic resumption and extrusion of the first polar body.

Porcine oocyte maturation in vitro : role of cAMP and oocyte-secreted factors: a practical approach [PDF]
, 2016 Polyspermy or the penetration of more than one sperm cell remains a problem during porcine in vitro fertilization (IVF). After in vitro culture of porcine zygotes, only a low percentage of blastocysts develop and their quality is inferior to that of in ...

Meiotic abnormalities in patients bearing complete AZFc deletion of Y chromosome [PDF]
Human Reproduction, 2007 We studied meiosis in three infertile patients presenting complete AZFc microdeletion and three controls.Primary spermatocytes were immunolabeled with SCP3, BRCA1 and gammaH2AX. We quantified the leptotene, zygotene and pachytene stages, and pachytene abnormalities: asynapsis and fragmented and dotted synaptonemal complexes (SCs).SCP3 level was ...
