EPIGENETIC RESETS “ensures proper development, the acquisition of parent-specific imprints, and might allow for mechanisms limiting the maximal number of possible successive mitoses (“Hayflick limit”, reducing tumour development." http://biorxiv.org/content/biorxiv/early/2016/04/28/050831.full.pdf View in LinkedIn

TWO RESETS. "Metazoan development is under the control of many epigenetic changes (cytosine methylation and chromatin marks) that are irreversibly maintained throughout life and must be reset twice each generation (at the n→2n and 2n→n transitions)." http://biorxiv.org/content/biorxiv/early/2016/04/28/050831.full.pdf View in LinkedIn

NO PLANT ARRESTS. "Meiotic arrests in plants are unknown. Plants seem to completely lack strict mechanisms to arrest the meiotic cell division. Contrary to animals and fungi that for example arrest the cell cycle and abort meiosis once double strand breaks are not repaired, plants will progress through meiosis irrespective of such major defects." http://biorxiv.org/content/biorxiv/early/2016/04/28/050831.full.pdf View in LinkedIn

GERMLINE. "In animals, where haploid mitosis is suppressed, syngamy immediately follows meiosis. Furthermore, specific cells are ‘destined’ at an early stage to eventually undergo meiosis (a.k.a germline), whereas this cell fate is determined much later in fungi, plants and some algae." https://lnkd.in/e2tp_G5 View in LinkedIn
