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 …

Gene expression has been employed for homologizing body regions across bilateria. The
molecular comparison of vertebrate and fly brains has led to a number of disputed homology …

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 …

Background Most of the known genes required for developmental processes have been
identified by genetic screens in a few well-studied model organisms, which have been …

Insect development has contributed significantly to our understanding of metazoan
development. However, most information has been obtained by analyzing a single species …

Wnt/β-catenin and hedgehog (Hh) signaling are essential for transmitting signals across cell
membranes in animal embryos. Early patterning of the principal insect model, Drosophila …

The speciation of a methanolic extract of Zanthoxylum armatum stem bark has enabled the
isolation and characterization of 11 known lignans. Among them, five compounds (6, 8–11) …

In insect embryos, anteroposterior patterning is coordinated by the sequential expression of
the 'timer'genes caudal, Dichaete, and odd-paired, whose expression dynamics correlate …

The apical plate of primary marine larvae is characterized by a common set of transcription
factors comprising six3, rx, hbn, nk2. 1 and FoxQ2. It harbours the apical organ, a neural and …

Patterning of the terminal regions of the Drosophila embryo is achieved by an exquisitely
regulated signal that passes between the follicle cells of the ovary, and the developing …
