Book Synopsis Role of Odorant-binding Proteins in Drosophila Melanogaster Chemosensory Perception by : Karen Rihani
Download or read book Role of Odorant-binding Proteins in Drosophila Melanogaster Chemosensory Perception written by Karen Rihani and published by . This book was released on 2019 with total page 540 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chemoperception is used by animals to detect nutritive food and avoid toxic compounds. It also allows animals to identify suitable ecological niche and mating partners. Like many other insects, Drosophila melanogaster possesses a very sensitive chemosensory ability and can detect and discriminate a wide panel of semiochemicals. Chemosensory detection is mostly mediated by olfactory and gustatory systems involving several multigene chemoreceptor families. Volatile and non-volatile chemical compounds entering the sensory organ (sensillum) must be solubilized before being transported through the hydrophilic sensillum lymph bathing the dendrites of chemosensory neurons. These perireceptor events involve a family of soluble proteins named odorant-binding proteins (OBPs). Despite the fact that OBPs were initially found in olfactory sensilla, some OBPs are also expressed in gustatory sensilla. While their physiological roles in olfaction and gustation remain unclear, many studies suggest that OBPs transport lipophilic chemicals. The relatively low affinity of OBPs for odorants and their high abundance in the sensillum lymph both suggest that OBPs can bind, solubilize and transport hydrophobic stimuli to the chemoreceptors across the aqueous sensilla lymph. In addition to this broadly accepted "transporter role" hypothesis, OBPs have also been proposed to buffer sudden changes in odorant levels and to be involved in hygroreception. The role of OBP49a was recently shown in taste: this OBP, expressed in the gustatory system, is required to detect some bitter compounds. However, the role of OBPs in perireceptor events remains largely unknown. The main goal of my thesis project consisted to investigate the involvement of OBPs in the smell and taste sensory modalities using a multi-faceted approach in Drosophila melanogaster.My first research axis consisted to better understand the role of OBPs in the perception of food compounds by using both in vitro and in vivo approaches of OBPs expressed in the gustatory appendages of D. melanogaster adults. After identifying by q-PCR the OBPs expressed in gustatory appendages, we produced them using a heterologous yeast expression system. Then, the binding properties of the recombinant purified OBP were investigated. Our binding assay screen revealed that the taste-expressed OBP19b is able to bind some amino acids. The expression of OBP19b was mapped in specific accessory cells in a subset of proboscis sensilla. This OBP was also expressed in the digestive tract and in some internal reproductive organs. The comparison of behavioural and single-taste sensilla responses between transgenic variants and control flies supported our finding that OBP19b is indeed involved in the detection of some amino acids. Finally, the comparison between various dipteran insects of the OBP19b-like protein coding sequence indicates the relatively high conservation of this protein suggesting its critical role in food search.The second research axis of my PhD thesis focused on the olfactory role of OBP28a. OBP28a was previously shown to be highly expressed in the Drosophila antennae and proposed to buffer quantitative odour variations. To better understand the physiological role of this OBP, and in collaboration with different members of the team, we used structural, genetic, biochemical, behavioural and electrophysiological methods to better understand the role of this OBP. OBP28a was first heterologously expressed and purified. The folding of OBP28a was then determined and the protein was crystallized. The study of the binding properties of OBP28a revealed that it can bind floral compounds such as [beta]-ionone. Behavioural and electrophysiological recordings supported the physiological role of OBP28a in [beta]-ionone detection. In summary, this PhD thesis reveals novel roles of two OBPs in perireceptor chemoreception: OBP28a in the detection of floral compounds and OBP19b in the detection of some amino acids.

Book Synopsis Neurobiology of Chemical Communication by : Carla Mucignat-Caretta
Download or read book Neurobiology of Chemical Communication written by Carla Mucignat-Caretta and published by CRC Press. This book was released on 2014-02-14 with total page 614 pages. Available in PDF, EPUB and Kindle. Book excerpt: Intraspecific communication involves the activation of chemoreceptors and subsequent activation of different central areas that coordinate the responses of the entire organism—ranging from behavioral modification to modulation of hormones release. Animals emit intraspecific chemical signals, often referred to as pheromones, to advertise their presence to members of the same species and to regulate interactions aimed at establishing and regulating social and reproductive bonds. In the last two decades, scientists have developed a greater understanding of the neural processing of these chemical signals. Neurobiology of Chemical Communication explores the role of the chemical senses in mediating intraspecific communication. Providing an up-to-date outline of the most recent advances in the field, it presents data from laboratory and wild species, ranging from invertebrates to vertebrates, from insects to humans. The book examines the structure, anatomy, electrophysiology, and molecular biology of pheromones. It discusses how chemical signals work on different mammalian and non-mammalian species and includes chapters on insects, Drosophila, honey bees, amphibians, mice, tigers, and cattle. It also explores the controversial topic of human pheromones. An essential reference for students and researchers in the field of pheromones, this is also an ideal resource for those working on behavioral phenotyping of animal models and persons interested in the biology/ecology of wild and domestic species.

Available in PDF, EPUB and Kindle. Book excerpt: Aphids are among the major global pest groups, causing serious economic damage to many food and commodity crops in most parts of the world. This revision and update of the well-received first edition published ten years ago reflects the expansion of research in genomics, endosymbionts and semiochemicals, as well as the shift from control of aphids with insecticides to a more integrated approach imposed by increasing resistance in the aphids and government restrictions on pesticides. The book remains a comprehensive and up-to-date reference work on the biology of aphids, the various methods of controlling them and the progress of integrated pest management as illustrated by ten case histories.

Book Synopsis Chemosensory Information Processing by : Detlev Schild
Download or read book Chemosensory Information Processing written by Detlev Schild and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 405 pages. Available in PDF, EPUB and Kindle. Book excerpt: In July 1989 a symposium was held at the Physiology Department of the Georg August University, G6ttingen, on the physiological, biophysical, biochemical, and technical principles of the coding of chemical substances both in nervous systems and artificial devices. This book is the collection of the papers presented at that meeting. Biological and artificial systems for odor coding both have in common that the stimulus selectivity of the receptor cells (sensors) is usually very poor, and the mechanisms which determine selectivity and sensitivity are largely unknown. However, a poor selectivity allows the coding of an enormous number of stimuli by combinations of receptor activities. In the field of chemosensory information coding there are thus two major problems: the function of the receptors and the network that processes and evaluates the primary information of the sensors. Accordingly, this volume has three parts: sensors, the network following the sensors, and the coding in this network. The expert secretarial assistance of M. Holtmann in preparing the camera-ready manuscript is gratefully acknowledged. D. Schild G6ttingen, August 1989 CONTENTS l.

Download or read book Bioelectronic Nose written by Tai Hyun Park and published by Springer Science & Business. This book was released on 2014-04-25 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: The “bioelectronic nose”, the device which has a similar function to the human smell sensing system, can be realized by combining the olfactory cells or receptors with nanotechnology. In the last two decades, much has been learned about the smell sensing mechanism in biological systems. With knowledge about the biological olfactory system and the techniques for the expression of biological receptor proteins, we are able to utilize biological materials and systems to mimic the biological olfactory system. In addition to the advances in biological and biotechnological area, nanotechnology has progressed to a great degree. The bioelectronic nose is a good example of the integration of biotechnology and nanotechnology. This book describes basic biological sciences of the olfactory system, biotechnology for the production of olfactory biological elements, and nanotechnology for the development of various sensing devices. The purpose of this book is to provide the reader with a concept, basic sciences, fundamental technologies, applications, and perspectives of the bioelectronic nose.
