To accommodate daily recurring environmental changes, animals show cyclic variations in
behaviour and physiology, which include prominent behavioural states such as sleep–wake …

The advantages of the model organism Drosophila melanogaster, including low genetic
redundancy, functional simplicity, and the ability to conduct large-scale genetic screens …

Aphids are important agricultural pests and also biological models for studies of insect-plant
interactions, symbiosis, virus vectoring, and the developmental causes of extreme …

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

Getting a good night's sleep is on everyone's to-do list. So is, no doubt, staying awake during
late afternoon seminars. Our internal clocks control these and many more workings of the …

Background Recent genomic analyses of arthropod defense mechanisms suggest
conservation of key elements underlying responses to pathogens, parasites and stresses. At …

An intrinsic clock enables an organism to anticipate environmental changes and use energy
sources more efficiently, thereby conferring an adaptive advantage. Having an intrinsic clock …

A genetic screen for mutants that alter circadian rhythms in Drosophila identified the first
clock gene—the period (per) gene. The per gene is a central player within a transcriptional …

Using a forward genetics ENU mutagenesis screen for recessive mutations that affect
circadian rhythmicity in the mouse, we isolated a long period (∼ 26 hr) circadian mutant …

The proteasome is a large multi-subunit protease responsible for the degradation and
removal of oxidized, misfolded, and polyubiquitinated proteins. The proteasome plays …
