Organogenesis: Drosophila goes gonadal.
In many animals, germ cells migrate to the gonad to assemble into a functional organ. Recent work in Drosophila has built a picture of the gene activities that specify the gonad and allow it to attract germ cells, and has led to the identification of a gene, columbus, that may encode the attractive factor.
