Gap genes are involved in segment determination during the early development of the fruit
fly Drosophila melanogaster as well as in other insects. This review attempts to synthesize …

SUMMARY RNA interference (RNAi) provides a powerful reverse genetics approach to
analyze gene functions both in tissue culture and in vivo. Because of its widespread …

We report here genome sequences and comparative analyses of three closely related
parasitoid wasps: Nasonia vitripennis, N. giraulti, and N. longicornis. Parasitoids are …

A marine ecosystem model seeded with many phytoplankton types, whose physiological
traits were randomly assigned from ranges defined by field and laboratory data, generated …

Oscillatory and sequential processes have been implicated in the spatial patterning of many
embryonic tissues. For example, molecular clocks delimit segmental boundaries in …

Localization of an mRNA species to a particular subcellular region can complement
translational control mechanisms to produce a restricted spatial distribution of the protein it …

Insects determine their body segments in two different ways. Short-germband insects, such
as the flour beetle Tribolium castaneum, use a molecular clock to establish segments …

Long-germ insects, such as the fruit fly Drosophila melanogaster, pattern their segments
simultaneously, whereas short-germ insects, such as the beetle Tribolium castaneum …

RNA localization serves numerous purposes from controlling development and
differentiation to supporting the physiological activities of cells and organisms. After a brief …

Studying the embryogenesis of diverse insect species is crucial to understanding insect
evolution. Here, we review current advances in understanding the development of two …
