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 …

Besides being a spectacular developmental process, metamorphosis is key to insect
success. Entry into metamorphosis is controlled by juvenile hormone (JH). In larvae, JH …

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 …

Abstract The iBeetle-Base (http://ibeetle-base. uni-goettingen. de) makes available
annotations of RNAi phenotypes, which were gathered in a large scale RNAi screen in the …

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

In Drosophila, a hierarchy of maternal, gap, pair-rule, and segment polarity gene interactions
regulates virtually simultaneous blastoderm segmentation. For the last decade, studies have …

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 …
