A microRNA family exerts maternal control on sex determination in C. elegans.

Determination of the effects of food preservatives benzoic acid and sodium nitrate on lifespan, fertility and physical growth in Caenorhabditis elegans

Presently, the use of protective food additives such as benzoic acid and sodium nitrate is quite common. However, it was found that these additives, which initially appeared to be harmless, led to the emergence of a number of health problems. Cancer and diseases and deaths with no apparent causes are among the leading concerns. Therefore, the studies which can reveal the genotoxic potential of ...

fog-2 and the Evolution of Self-Fertile Hermaphroditism in Caenorhabditis

Somatic and germline sex determination pathways have diverged significantly in animals, making comparisons between taxa difficult. To overcome this difficulty, we compared the genes in the germline sex determination pathways of Caenorhabditis elegans and C. briggsae, two Caenorhabditis species with similar reproductive systems and sequenced genomes. We demonstrate that C. briggsae has orthologs...

Revisiting the X:A signal that specifies Caenorhabditis elegans sexual fate.

In Caenorhabditis elegans, sex is determined by the opposing actions of X-signal elements (XSEs) and autosomal signal elements (ASEs), which communicate the ratio of X chromosomes to sets of autosomes (X:A signal). This study delves more deeply into the mechanism by which XSEs transmit X chromosome dose. We determined the relative contributions of individual XSEs to the X:A signal and showed th...

A Low-Cost Efficient Multiplex P CR for Prenatal Sex Determination in Bovine Fetus U sing Free Fetal DNA in Maternal Plasma

The evolution of nematode sex determination: C. elegans as a reference point for comparative biology.

Sex determination was a founding topic of C. elegans research. After three decades of research, a complex signal transduction pathway with multiple layers of regulation has been elucidated. This pathway links karyotype to phenotype by coordinating the development of sexually dimorphic tissues. In this article, this pathway is placed in two broader contexts. The first is that of nematodes and an...
