TL;DR: Three isoforms of the zebrafish Dmrt1 were generated in gonads by multiple alternative splicing, which encoded predicted proteins with 267, 246, and 132 amino acids, respectively, suggesting that the DmRT1 gene is not only associated with testis development, but also, may be important in ovary differentiation of zebra fish.

TL;DR: It is reported that four isoforms of dmrt1 (dsx- and mab3-related transcription factor 1) are generated in testis, ovotestis, and ovary by alternative splicing in the rice field eel, a fresh water fish that undergoes natural sex reversal from female to male during its life cycle.

TL;DR: It is shown that the Sox9a gene was duplicated during evolution of the rice field eel, Monopterus albus, a freshwater fish which undergoes natural sex reversal from female to male during its life, and has a haploid genome size that is among the smallest of the vertebrates.

TL;DR: A critical regulator of hermaphrodite development in C. briggsae is identified and molecular cloning shows that she-1 encodes a novel F box protein that was created by a recent gene duplication, which implies that some gene families are more likely to give rise to novel regulatory genes than other families.

TL;DR: Molecular cloning, sequence, and expression of zebrafish Dmrt5 are reported, which consists of two exons, and encodes a 440-amino acid protein with conserved DMA and DMB domains in addition to DM domain, suggesting that zebra fish DmRT5 have potentially important roles in gonadal development and may have contributed to the functional endocrine axis.
