Understanding Transcription Factors and How They Affect Processes in Cucumber Sex Determination [PDF]

open access: yesMetabolites, 2023
Plant reproduction is a fundamental process on Earth from the perspective of biodiversity, biomass gain, and crop productivity. It is therefore important to understand the sex determination process, and many researchers are investigating the molecular ...

Sex Determination and Differentiation in Teleost: Roles of Genetics, Environment, and Brain [PDF]

open access: yesBiology, 2021
The fish reproductive system is a complex biological system. Nonetheless, reproductive organ development is conserved, which starts with sex determination and then sex differentiation.

Sex chromosome evolution mediated by a large inversion and a possible switch of the sex determination gene [PDF]

open access: yesGenome Biology
Background Sex chromosomes often evolve faster than autosomes and commonly degenerate after recombination arrest. However, the underlying evolutionary processes are under persistent debate. In particular, it is unclear whether or not recombination arrest

Exposure to Glyphosate and Chlorpyrifos Induces Oxidative Stress, Potentially Impacting Sex Determination in Zebrafish (Danio rerio) [PDF]

open access: yesJournal of Xenobiotics
The widespread use of pesticides in agriculture has increased their levels in water bodies, threatening aquatic ecosystems. Among these, glyphosate and chlorpyrifos are widely used in Mexico and can cause toxic effects even at low doses.

Whole-Genome Methylation Analysis of Female, Male, and Neomale Northern Pike (Esox lucius) [PDF]

open access: yesAnimals
To investigate the effect of epigenetic modifications on sex determination and differentiation in northern pike (Esox lucius), we employed Whole-Genome Bisulfite Sequencing (WGBS) to analyze the DNA methylation patterns in gonadal tissues of females ...

The regulatory role of m6A RNA methylation in insect sexual development: a review [PDF]

open access: yesFrontiers in Cell and Developmental Biology
N6-methyladenosine (m6A) is the most prevalent internal mRNA modification in eukaryotes and serves as a key post-transcriptional regulator in insect development.

Sex determination in honeybees: two separate mechanisms induce and maintain the female pathway. [PDF]

open access: yesPLoS Biology, 2009
Organisms have evolved a bewildering diversity of mechanisms to generate the two sexes. The honeybee (Apis mellifera) employs an interesting system in which sex is determined by heterozygosity at a single locus (the Sex Determination Locus) harbouring ...

Evidence for a genetic sex determination in Cnidaria, the Mediterranean red coral (Corallium rubrum) [PDF]

open access: yesRoyal Society Open Science, 2017
Sexual reproduction is widespread among eukaryotes, and the sex-determining processes vary greatly among species. While genetic sex determination (GSD) has been intensively described in bilaterian species, no example has yet been recorded among non ...

Hermaphroditism in Cannabis sativa L.: Impacts, Inducers, and Industry Implications [PDF]

open access: yesPlants
Cannabis sativa L. is a predominantly dioecious species, but sex expression is highly plastic and can be modified by genetic, hormonal, developmental, and environmental factors.

Comparative RNA-Seq Analysis of Differentially Expressed Genes in the Testis and Ovary of Mudskipper, Boleophthalmus pectinirostris [PDF]

open access: yesAnimals
Sex determination and differentiation in teleosts are governed by complex genetic regulatory networks that include evolutionarily conserved mechanisms. In this study, we investigated Boleophthalmus pectinirostris, a Gobiidae species lacking heterogametic
