Oxidative stress causes loss of meiotic cohesion [Cell Biology]>

Edit PNAS 18 Oct 2016
In humans, errors in meiotic chromosome segregation that produce aneuploid gametes increase dramatically as women age, a phenomenon termed the “maternal age effect.” During meiosis, cohesion between sister chromatids keeps recombinant homologs physically attached and premature loss of cohesion can lead to missegregation of homologs during meiosis I. A growing... ....

P31comet in rice meiosis [Cell Biology]>

Edit PNAS 20 Sep 2016
The human mitotic arrest-deficient 2 (Mad2) binding protein p31comet participates in the spindle checkpoint and coordinates cell cycle events in mitosis although its function in meiosis remains unknown in all organisms. Here, we reveal P31comet as a synaptonemal complex (SC) protein in rice (Oryza sativa L.). In p31comet, homologous pairing... ....

Scientists identify Down's Syndrome gene (University of Salford)

Edit Public Technologies 09 Aug 2016
'Understanding how meiosis is regulated is of great importance to understanding the causes of aneuploidy and genetic disorders in humans.'. The scientists looked at a process known as meiosis, which unlike normal cell division (mitosis) has two rounds of nuclear division, to ensure that when sex cells fuse with each other, they have two copies of each chromosome - one from each parent!....

Dr. Arp Schnittger, from University of Hamburg, dealt with the 'mysteries of meiosis', an essential genetic mechanism poorly understood in plants. His group has identified several key regulatory components, which determine the processes of entry into germ line, and that might be relevant to understand unequal DNA recombination during plant meiosis, a bottle neck in crop breeding. Dr....
