Sex-Specific Odorant Receptors of the Tobacco Hornworm Manduca Sexta
As odor information plays a vital role in the life of moths, their olfactory sense has evolved into a highly specific and sensitive apparatus relevant to reproduction and survival. The key players in the detection of odorants are olfactory receptor (OR) proteins. Here we identify four OR-encoding genes differentially expressed in the antennae of males and females of the sphingid moth Manduca se...
متن کاملStructure-activity relationship of ETH during ecdysis in the tobacco hornworm, Manduca sexta.
In insects, ecdysis or shedding of the old cuticle, consists of a series of behaviors that are regulated by the coordinated actions of a number of neuropeptides, one of which is ecdysis triggering hormone (ETH). ETH acts directly on central pattern generators of the abdominal ganglia to trigger onset of pre-ecdysis behaviors, as well as indirectly to activate release of eclosion hormone, thereb...
متن کاملA pattern recognition serine proteinase triggers the prophenoloxidase activation cascade in the tobacco hornworm, Manduca sexta.
A serine proteinase cascade in insect hemolymph mediates prophenoloxidase activation, a defense mechanism against pathogen or parasite infection. Little is known regarding its initiating proteinase or how this enzyme is activated in response to invading microorganisms. We have isolated from the tobacco hornworm, Manduca sexta, a cDNA encoding a modular protein designated hemolymph proteinase 14...
متن کاملLipoprotein biosynthesis in the larvae of the tobacco hornworm, Manduca sexta.
Lipoprotein biosynthesis in larvae of the tobacco hornworm (Manduca sexta) was investigated. By immunoblotting, it was shown that the apoproteins are present in the fat body, but not in the midgut. Fat body incubated in vitro with [35S]methionine secreted labeled apoproteins. However, when the density of the secreted particle was determined, it was found at 1.24-1.28 g/ml instead of 1.15 g/ml, ...
متن کاملMultifaceted biological insights from a draft genome sequence of the tobacco hornworm moth, Manduca sexta.
Manduca sexta, known as the tobacco hornworm or Carolina sphinx moth, is a lepidopteran insect that is used extensively as a model system for research in insect biochemistry, physiology, neurobiology, development, and immunity. One important benefit of this species as an experimental model is its extremely large size, reaching more than 10 g in the larval stage. M. sexta larvae feed on solanace...
