Embryonic Treatment with Xenobiotics Disrupts Steroid Hormone Profiles in Hatchling Red-Eared Slider Turtles (Trachemys scripta elegans).

From: Environmental Health Perspectives | Date: April 1, 2000| Author: Crews, David; Rhen, Turk; Sakata, Jon T.; Willingham, Emily | Copyright information

Many compounds in the environment capable of acting as endocrine disruptors have been assayed for their developmental effects on morphogenesis; however, few studies have addressed how such xenobiotics affect physiology. In the current study we examine the effects of three endocrine-disrupting compounds, chlordane, trans-nonachlor, and the polychlorinated biphenyl (PCB) mixture Aroclor 1242, on the steroid hormone concentrations of red-eared slider turtle (Trachemys scripta elegans)...

Amh and Dmrta2 Genes Map to Tilapia (Oreochromis spp.) Linkage Group 23 Within Quantitative Trait Locus Regions for Sex Determination
Genetics ; ABSTRACT Recent studies have revealed that the major genes of the mammalian sex determination pathway are also involved in sex determination of fish. Several studies have reported QTL in various species and strains of tilapia, regions contributing to sex determination have been identified on
Sex-Determining Mechanisms in Land Plants
Plant Cell ; ... 1-aminocyclopropane-l-carboxylic acid synthase genes, CS-ACSI and CS-ACS2, have been identified in cucumber, and one of them (CS-ACS1) maps to the F locus (Trebitsh et al., 1997). The monoecious cucumber genome has only one copy (Cs-ACSI), whereas the gynoecious genome ...

Plant Physiology ; Dioecious Plants. A Key to the Early Events of Sex Chromosome Evolution1 Around 200 BC, the Nordic tribes devised rune symbols to represent the forces of nature. Among these symbols were X-GEBA, the rune of love and sexuality, and Y-FEOH, the rune of success. It was believed that by picking the

Comparative Genetics of Sex Determination: Masculinizing Mutations in Caenorhabditis briggsae
Genetics ; ABSTRACT The nematodes Caenorhabditis elegans and C. briggsae independently evolved self-fertile hermaphroditism from gonochoristic ancestors. C. briggsae has variably divergent orthologs of nearly all genes in the C. elegans sex determination pathway. Their functional characterization has

China restricts sex-selective abortion.(Law and Policy)(Brief Article)
Reproductive Health Matters ; In China, where boys are still often more welcome than girls and where limits on child numbers are officially sanctioned, sex determination tests during pregnancy are leading to the abortion of female fetuses. In an attempt to stop this practice, the Chinese government has issued a regulation
The Gene doublesex of the Fruit Fly Anastrepha obliqua (Diptera, Tephritidae)
Genetics ; ABSTRACT The gene doublesex of Anastrepha obliqua is composed of four instead of the usual six exons. It is transcribed in both sexes and its primary transcript undergoes sex-specific splicing, producing female Dsx^sup F^ and male Dsx^sup M^ proteins, which have in common the amino-terminal region
