Pedro Beltrao at Public Rambling gets inspiration from and makes use of a recently published Cell paper to do a quick analysis of the potential effects of mRNA localization patterns in the developing D. melanogaster embryo. The paper found that a large fraction of the genes had localization patterns during some stage of the embryonic development. Beltrao used this knowledge along with Fly-FISH, a database documenting these expression patterns, to conclude that "the degree of mRNA co-localization significantly correlates with the likelihood of genetic or physical association."
