An orchestrated intron retention program in meiosis controls timely usage of transcripts during germ cell differentiation [PDF]
, 2017 Global transcriptome reprogramming during sper-matogenesis ensures timely expression of factors in each phase of male germ cell differentiation. Sper-matocytes and spermatids require particularly exten-sive reprogramming of gene expression to switch from

Crystal structure of Hop2-Mnd1 and mechanistic insights into its role in meiotic recombination [PDF]
, 2015 In meiotic DNA recombination, the Hop2-Mnd1 complex promotes Dmc1-mediated single-stranded DNA (ssDNA) invasion into homologous chromosomes to form a synaptic complex by a yet-unclear mechanism.

Common but Least Noticed: Diversity of the Mangrove Fern Acrostichum aureum in Hainan Island, China
Biological Diversity, EarlyView.Acrostichum aureum across nine coastal sites in Hainan Island was examined using morphological, cytometric, and genomic approaches. Three priority conservation areas are proposed to preserve extant genetic diversity and maintain habitat connectivity. ABSTRACT Acrostichum aureum across nine coastal sites in Hainan Island was examined using morphological,

Nature Communications, 2016 Meiosis is a cell division program that produces haploid gametes and is initiated by a retinoic acid-dependent process. Here the authors report that a meiosis-specific protein, MEIOC, is upregulated in a retinoic acid-independent manner and is required ...

The conserved XPF:ERCC1-like Zip2:Spo16 complex controls meiotic crossover formation through structure-specific DNA binding. [PDF]
, 2019 In eukaryotic meiosis, generation of haploid gametes depends on the formation of inter-homolog crossovers, which enable the pairing, physical linkage, and eventual segregation of homologs in the meiosis I division.

C-banding, fluorescent staining and NOR location in holokinetic chromosomes of bugs of the Neotropical genus Antiteuchus (Heteroptera: Pentatomidae: Discocephalinae) [PDF]
, 2006 Different cytogenetic techniques including C-banding, base-specific fluorochromes and silver nitrate staining were used to compare the karyotypes of three species of bugs, representatives of the Neotropical genus Antiteuchus, namely A.

Breaking barriers: the cGAS‐STING pathway as a novel frontier in cancer immunotherapy
Cancer Communications, EarlyView.Abstract Since its discovery, the cyclic GMP‐AMP synthase (cGAS)‐stimulator of the interferon gene (STING) signaling pathway has been considered a pivotal component of innate immunity and a promising target for cancer immunotherapy. Beyond its canonical role in pathogen defense, accumulating evidence has demonstrated that the cGAS‐STING pathway ...

Meiosis-specific gene discovery in plants: RNA-Seq applied to isolated
BMC Plant Biology, 2010 Background Meiosis is a critical process in the reproduction and life cycle of flowering plants in which homologous chromosomes pair, synapse, recombine and segregate. Understanding meiosis will not only advance our knowledge of the mechanisms of genetic

A Meiotic Checkpoint Alters Repair Partner Bias to Permit Inter-sister Repair of Persistent DSBs [PDF]
, 2019 Accurate meiotic chromosome segregation critically depends on the formation of inter-homolog crossovers initiated by double-strand breaks (DSBs). Inaccuracies in this process can drive aneuploidy and developmental defects, but how meiotic cells are ...
