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

Employing the clear, student-friendly style that made previous editions so popular, Insect
Physiology and Biochemistry, Fourth Edition presents an engaging and authoritative guide …

A key problem in development is to understand how genes turn on or off at the right place
and right time during embryogenesis. Such decisions are made by non-coding sequences …

Cells in a developing animal embryo become specified by the activation of cell-type-specific
gene regulatory networks. The network that specifies the gut in the nematode …

During development, cells gradually assume specialized fates via changes of transcriptional
dynamics, sometimes even within the same developmental stage. For anterior-posterior (AP) …

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 …

Developing tissues are patterned in space and time; this enables them to differentiate their
cell types and form complex structures to support different body plans. Although space and …

The Drosophila blastoderm gene regulatory network is one of the best studied networks in
biology. It is composed of a series of tiered sub-networks that act sequentially to generate a …

The cis-regulatory data that help in transcriptional regulation is arranged into modular
pieces of a few hundred base pairs called CRMs (cis-regulatory modules) and numerous …

Understanding embryonic patterning, the process by which groups of cells are partitioned
into distinct identities defined by gene expression, is a central challenge in developmental …
