Abstract: During gametogenesis and embryonic development, precise regulation of gene expression, across cell/tissue types and over time, is crucial. In vertebrates, transcription is partly regulated by histone lysine acetylation/deacetylation, an epigenetic mechanism mediated by lysine acetyltransferases (KAT) and histone deacetylases (HDAC). Well characterized in mammals, these enzymes are unknown in fish embryology outside of zebrafish development. Here, we characterized putative KAT and HDAC enzymes in the self-fertilizing mangrove rivulus fish, Krypt...
