DOI: 10.1002/jcp.26467
Abstract: In mammals, journey from metaphase‐I (M‐I) to metaphase‐II (M‐II) is important since oocyte extrude first polar body (PB‐I) and gets converted into haploid gamete. The molecular and cellular changes associated with meiotic cell cycle progression… read more here.

DOI: 10.1091/mbc.e19-07-0405
Abstract: Metaphase spindles exert pole-directed forces on still-connected sister kinetochores. The spindle must counter these forces with extensive forces to prevent spindle collapse. In small spindles, kinetochore microtubules (KMTs) connect directly with the poles, and countering… read more here.

DOI: 10.1093/nar/gkad028
Abstract: Abstract Chromatids of mitotic chromosomes were suggested to coil into a helix in early cytological studies and this assumption was recently supported by chromosome conformation capture (3C) sequencing. Still, direct differential visualization of a condensed… read more here.

DOI: 10.1242/jcs.252924
Abstract: Mammalian oocytes are arrested at meiotic prophase I. The dual-specificity phosphatase CDC25B is essential for cyclin-dependent kinase 1 (CDK1) activation that drives resumption of meiosis. CDC25B reverses the inhibitory effect of the protein kinases WEE1/MYT1… read more here.

DOI: 10.1371/journal.pone.0241749
Abstract: Pleurotus ostreatus, one of the most widely cultivated edible mushrooms, produces high numbers of spores causing severe respiratory health problems for people, clogging of filters and spoilage of produce. A non-sporulating commercial variety (SPOPPO) has… read more here.

DOI: 10.3390/genes13020195
Abstract: Oligo-fluorescence in situ hybridization (FISH) facilitates precise chromosome identification and comparative cytogenetic analysis. Detection of autosomal chromosomes of Hippophaë rhamnoides has not been achieved using oligonucleotide sequences. Here, the chromosomes of five H. rhamnoides taxa… read more here.
