Transcriptional landscape of the embryonic chicken Müllerian duct. The images or other third party material in this article are included in the article's Creative Commons licence, unless indicated otherwise in a credit line to the material. Wnt4 is expressed in the mesenchyme of the duct and is required for proper duct formation in ro- dent models [22]. Genes known to...

However, some specific characters hindered achievement of the traditional selective breeding based on phenotypes, such as lack of large-scale genomic resource and short of markers tightly associated with growth, sex determination and hypoxia tolerance related traits.. The map ’ length was 4047.01 cM by using an interval of 0.11 cm, which is an average marker standard.. The images or other...

It has a male heterogametic (XX/XY) sex determination system that relies on both genetic and environmental factors, with high temperatures being able to produce female-to-male sex reversal. Little, however, is currently known on the molecular basis of genetic sex determination in this important cyprinid model. Here we used sequencing approaches to better characterize sex determination and sex-chromosomes in an experimental...

Background: The Yesso scallop, Patinopecten (Mizuhopecten) yessoensis, is a commercially important bivalve in the coastal countries of Northeast Asia. It has complex modes of sex differentiation, but knowledge of the mechanisms underlying this sex determination and differentiation is limited.. Forty-nine genes in the five modules involved in sex differentiation or determination were identified and selected to construct a gene co-expression...

Background: A complete understanding of the genetic basis for sexual determination and differentiation is necessary in order to implement efficient breeding schemes at early stages of development. This instability together with the capacity of the sex-determining gene to move across the genome as reported by previous studies, may explain that sexual development genes are not circumscribed to the same chromosomes...

Genome-wide profiling of the alternative splicing provides insights into development in Plutella xylostella. We also identified 1804 genes showing alternative splicing (AS) in each of the developmental stages and sexes, suggesting that AS events are ubiquitous in DBM. Comparative analyses showed that these AS events were rarely shared among developmental stages, indicating that they may play key specific roles in...

The analysis of the tra locus in sand flies and its expression pattern suggest that this gene is able to autoregulate its own splicing, as observed in the fruit fly Ceratitis capitata and several other insect species.. In female em- bryos, the maternal tra contribution establishes the female-specific autoregulatory splicing of tra and leads to female development, which is epigenetically...

alternative splicing in sex determination in mice. Differentially expressed isoform analysis identified hundreds of specific isoforms related to GSD, many of which showed no differences in the DEG analysis. Gonadal sex determination (GSD) is the primary event in mammalian sexual development during which bipotential gonads differentiate into either testes (in males) or ovaries (in females). This decision is made after...

Contrary to expectations, we found highly differential expression of colour pattern (CP) genes in the gonads, suggesting the ‘ neofunctionalisation ’ of those genes in the zebrafish reproduction system. However, in the caudal fin, no differential expression of CP genes was identified, suggesting the observed differences in colouration between males and females in adult fish may be due to post-transcriptional...

Background: In the animal kingdom, mollusca is an important phylum of the Lophotrochozoa. This individual long-term monitoring gave us the opportunity to explain the molecular expression patterns in the light of the most statistically likely future sex of each oyster.. 2 Laboratoire de Biologie des Organismes et Ecosystèmes Aquatiques (BOREA), Université de Caen Normandie, MNHN, SU, UA, CNRS, IRD, Esplanade...

Alternative patterns of sex chromosome differentiation in Aedes aegypti (L). We also previously described a proposed cryptic subspecies SenAae (PK10, Senegal) that had many more high inter-sex F ST genes on chromosome 1 than did Ae.aegypti aegypti (Aaa, Pai Lom, Thailand). There were 85 genes common to both collections with high inter-sex F ST values. Aaa showed the expected cluster...

Full list of author information is available at the end of the article. The majority of the SA markers were, based on positions in the S. Based on segregation differences of the alleles at the two marker positions and on differences in PCR amplification between females and males we conclude that females had multiple copies of this DNA fragment (chromosome...
