TL;DR: This article found an excess of gene duplications in the East African lineage compared to Nile tilapia and other teleosts, an abundance of non-coding element divergence, accelerated coding sequence evolution, expression divergence associated with transposable element insertions, and regulation by novel microRNAs.

TL;DR: It is concluded that a number of molecular mechanisms shaped East African cichlid genomes, and that amassing of standing variation during periods of relaxed purifying selection may have been important in facilitating subsequent evolutionary diversification.

Environment and sex determination in farmed fish
TL;DR: In gonochoristic fish, steroid hormones with estrogens in females and 11-oxygenated androgens in males, are probably key physiological steps in the regulation of gonadal sex differentiation.
Journal ArticleDOI
Environmental effects on fish sex determination and differentiation.
TL;DR: In tilapia and sea bass, domestic stocks and field-collected populations showed similar patterns of thermosensitivity under controlled conditions, and transitional forms within a genetic sex determination (GSD) and environmental sexdetermination (ESD) continuum seem to exist.
Journal ArticleDOI
DMRT1 expression during gonadal differentiation and spermatogenesis in the rainbow trout, Oncorhynchus mykiss
Oriane Marchand,Marina Govoroun,Helena D'Cotta,Oonagh Marie McMeel,Jean-Jacques Lareyre,Alain Bernot,Vincent Laudet,Yann Guiguen +7 more
TL;DR: Cloned a DMRT1 homologue in the rainbow trout showed that this gene is expressed during testicular differentiation, but not during ovarian differentiation, and new DM-domain homologous sequences in fish suggest that at least four different genes bearing 'DM-domain' (DMRT genes) exist in fish just as in all vertebrate genomes.
