Transmission of an entire human chromosome through the mouse male germline reveals an unexpectedly high tolerance of aneuploidy during male meiosis and results in accurate transcriptional deployment despite massive epigenetic remodeling during spermatogenesis.
Post-transcriptional control by YTHDC2 is required to turn off the mitotic proliferation program and facilitate proper expression of the meiotic program to allow a clean cell fate transition in the germline stem cell lineage.
JNK pathway activity induces spermatogonial dedifferentiation under challenging conditions to maintain the germline stem cell pool and to endow it with potentially fitter cells that have increased proliferation.
Male C. elegans die through two distinct mechanisms – mating-induced germline activation, and potent male pheromone toxicity – but the latter is unique to males of androdioecious species (made up of hermaphrodites and males).
A Drosophila fertility gene is identified that acts as a linker between HP1a and local H3K4 demethylation during HP1a-mediated gene silencing that is required for ovary development and transposon silencing..
