The all-female Amazon molly (Poecilia formosa) originated from a single hybridization of two bisexual ancestors, Atlantic molly (Poecilia mexicana) and sailfin molly (Poecilia latipinna). As a gynogenetic species, the Amazon molly needs to copulate with a heterospecific male, but the genetic information of the sperm-donor does not contribute to the next generation, as the sperm only acts as the trigger for the diploid eggs’ embryogenesis. Here, we study the sequence evolution and gene… Expand
Allele-specific expression at the androgen receptor alpha gene in a hybrid unisexual fish, the Amazon molly (Poecilia formosa)
TLDR
Estimation of ASE of the androgen receptor alpha (arα) gene in several distinct tissues of Amazon mollies found an allelic bias favoring the maternal ancestor (P. mexicana) allele in ovarian tissue and an association between an Indel in a known CpG island and differential expression. Expand
The gonadal transcriptome of the unisexual Amazon molly Poecilia formosa in comparison to its sexual ancestors, Poecilia mexicana and Poecilia latipinna
TLDR
The hypothesis of general down-regulation of meiosis-related genes in the apomictic Amazon molly is supported and the obtained dataset and identified gene catalog will serve as a resource for future research on the molecular mechanisms behind the reproductive mode of this unisexual species. Expand
Transcriptomic analysis of female and male gonads in juvenile snakeskin gourami (Trichopodus pectoralis)
TLDR
RNA-seq analysis identified global genes that were associated with ovary and testis differentiation in the juvenile phase of the snakeskin gourami and provide valuable transcriptomic bioinformation for further investigation of reproductive biology and applications of sex manipulation. Expand
Characterization and expression of androgen receptors in olive flounder.
TLDR
The results imply that arα1, arα2 and arβ are sex-related genes and they might play important roles in gonadal differentiation in flounder. Expand

Comparative analysis of the gonadal transcriptomes of the all-female species Poecilia formosa and its maternal ancestor Poecilia mexicana
TLDR
The first de novo assembled transcriptome of the Amazon molly in comparison with its maternal ancestor, the Atlantic molly Poecilia mexicana is provided and the presence of 30 meiosis-specific genes within a species where no meiosis is known to take place is remarkable and raises new questions for future research.

Expression and Sequence Evolution of Aromatase cyp19a1 and Other Sexual Development Genes in East African Cichlid Fishes
Sex determination mechanisms are highly variable across teleost fishes and sexual development is often plastic. Nevertheless, downstream factors establishing the two sexes are presumably conserved.Expand
The fate of the duplicated androgen receptor in fishes: a late neofunctionalization event?
TLDR
The comparison of the mutations present in these divergent AR-B with those known in human to be implicated in complete, partial or mild androgen insensitivity syndrome suggests that the existence of two distinct AR duplicates may be correlated to specific functional differences that may be connected to the well-known plasticity of sex determination in fish.

INTERSPECIFIC HYBRIDIZATION AND THE EVOLUTIONARY ORIGIN OF A GYNOGENETIC FISH, POECILIA FORMOSA
In recent years, largely through the application of allozyme techniques, several unisexual (thelytokous) vertebrates have been shown to be genetically equivalent to F1 hybrids of certain relatedExpand
Unusual triploid males in a microchromosome-carrying clone of the Amazon molly, Poecilia formosa
TLDR
The probably aneuploid sperm from P. formosa males can trigger parthenogenetic development of unreduced eggs and show a deviation from the typical 23 bivalents in the synaptonemal complexes as well as in diakinesis due to the triploid state. Expand
Correlated evolution of androgen receptor and aromatase revisited.
TLDR
The analyses demonstrate that the invertebrate genes used in the previous analysis are not orthologous sequences but instead represent a diverse set of nuclear receptors and CYP enzymes with no confirmed or hypothesized relationships with androgens, and show that their analytical approach potentially led to spurious significant relationships due simply to conserved domains.

EVOLUTIONARY ORIGIN OF A PARTHENOFORM, THE AMAZON MOLLY POECILIA FORMOSA, ON THE BASIS OF A MOLECULAR GENEALOGY
TLDR
DNA sequence analyses of transcribed portions of the genome (tyrosine kinase proto‐oncogenes) demonstrated the Amazon molly Poecilia formosa hybrid state unequivocally and dates the hybridization event further back than would have been predicted on the basis of “Muller's ratchet” for an ecologically successful species.

The role of androgens in species recognition and sperm production in Atlantic mollies (Poecilia mexicana)
TLDR
It is predicted that one or more of the sex steroid hormones in teleost fish (11-ketotestosterone (KT), testosterone (T), and estradiol (E)) will play a role in species recognition (during mate choice and/or sperm priming) for Atlantic mollies (the maternal parental species) that are sympatric with Amazon mollie.

Microsatellites for the gynogenetic Amazon molly,Poecilia formosa: useful tools for detection of mutation rate, ploidy determination and overall genetic diversity
TLDR
Results of cross-amplification of 63 microsatel-lite loci, originally developed for Xiphophorus, tested in the Amazon molly and its two parental species P. mexicana and P. latipinna are reported, finding eight microsatellite loci were found to be poly-morphic. Expand
Monophyletic origin of multiple clonal lineages in an asexual fish (Poecilia formosa)
TLDR
The molecular phylogenetic evidence and the failure to resynthesize the gynogenetic P. formosa together with the old age of the species indicate that some unisexual vertebrates might be rare not because they suffer the long‐term consequences of clonal reproduction but because they are only very rarely formed as a result of complex genetic preconditions necessary to produce viable and fertile clonal genomes and phenotypes.
