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 …

The red flour beetle Tribolium castaneum has emerged as an important insect model system
for a variety of topics. With respect to studying gene function, it is second only to the vinegar …

Tribolium castaneum is a member of the most species-rich eukaryotic order, a powerful
model organism for the study of generalized insect development, and an important pest of …

Genetic screens are powerful tools to identify the genes required for a given biological
process. However, for technical reasons, comprehensive screens have been restricted to …

Most of our knowledge about the mechanisms of segmentation in arthropods comes from
work on Drosophila melanogaster. In recent years it has become clear that this mechanism …

There is now compelling evidence that many arthropods pattern their segments using a
clock-and-wavefront mechanism, analogous to that operating during vertebrate …

RNA interference (RNAi) is becoming a practical tool to control insect pests. Many mysteries
of how double-stranded RNA (dsRNA) is transported into, within, and between cells to …

Segmentation genes in insects are required for generating the subdivisions of the early
embryo. We describe here a new member of the gap family of segmentation genes in the …

Animals from all major clades have evolved a segmented trunk, reflected in the human spine
or the insect segments. These units emerge during embryogenesis from a posterior segment …

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