The gene lin-3 encodes an inductive signal for vulval development in C. elegans
Article Abstract:
The lin-3 gene stimulates the anchor cell to cause the development of the vulva from vulval precursor cells in the nematode Caenorhabditis elegans. The gene accomplishes this induction by encoding a molecule that resembles epidermal growth factor (EGF) and transforming growth factor-alpha. Moreover, the gene functions through the EGF receptor homologue let-23. This research illuminates the process of induction, the developmental process by which one set of cells determines the growth of another set of cells.

C. elegans lin-45 raf gene participates in let-60 ras-stimulated vulval differentiation
Article Abstract:
Genetic and molecular annalysis of the lin-45 raf gene indicates that it plays a major role in the vulval differentiation in Caenorhabtis elegans. This particular gene performs its role by encoding a family of serine and threonine kinases. Results of the experiment also indicated that the lin-45 raf protein appears after the ras protein in this transduction pathway. Researchers believe that such a process occurs in other metazoans.

Sinistral nematode population
Article Abstract:
Nematodes of the order Rhabditida generally show dextral asymmetry of the body plan. The existence of anterior gonadal arm on the right side of the intestines in nematodes defines their overall body handedness. However, the nematode, Acrobeloides bodenheimeri, of the same order displays reversed, sinistral, handedness. However, reversed handedness has no effect on mating ability.
