An approach described in PLoS Pathogens in July allowed British researchers to peer inside fruit fly embryos to track fluorescent versions of the bacterium Photorhabdus asymbiotica.

In both mouse and fruit fly embryos, Detlev Arendt, an evolutionary biologist at the European Molecular Biology Laboratory in Heidelberg, Germany, has found that cells involved in forming the brain and nerve cord divide into three columns of cells.

A regulatory factor called Dorsal controls a network of genes crucial for development of fruit fly embryos.

(Drosophila, or fruit flies, are a frequently used model for understanding human disease, and oskar is critical for normal development of fruit fly embryos.)

He and his team at the Max Planck Institute of Immunobiology and Epigenetics in Freiburg, Germany used fruit flies to explore how epigenetic modifications are transmitted from the mother to the embryo.

Therefore the researchers used a variety of genetic tools in fruit flies to remove the enzyme that places H3K27me3 marks and discovered that embryos lacking H3K27me3 during early development could not develop to the end of embryogenesis.

Clicking through 5000 hypertext links on the site's 1500 pages, visitors can trace the complex web of gene expression and protein action that transforms the fruit fly from a one - celled embryo into a six - legged adult, exactly as the saga unfolds in real - life flies.
