These tiny reef fish harbor luminous bacteria, and the chromosome-level assembly of the species’ genome may facilitate the duo’s use as a vertebrate model for symbiosis.
The Sloan Kettering researcher used mutagenic screening to probe genes and molecular pathways, including Toll and Hedgehog, essential to development in fruit flies and mice.
Studies The Scientist covered this year illustrate the expanding importance of genetic and genomic research in all aspects of life science, from ecology to medicine.
Evidence is mounting that epigenetic marks on DNA can influence future generations in a variety of ways. But how such phenomena might affect large-scale evolutionary processes is hotly debated.
