Characterization and genetic dissection of resistance to spotted alfalfa aphid (Therioaphis trifolii) in Medicago truncatula
Aphids cause significant yield losses in agricultural crops worldwide. Medicago truncatula, a model legume, cultivated pasture species in Australia and close relative of alfalfa (Medicago sativa), was used to study the defence response against Therioaphis trifolii f. maculate [spotted alfalfa aphid (SAA)]. Aphid performance and plant damage were compared among three accessions. A20 is highly su...
متن کاملUltrastructural Characterization of Olfactory Sensilla and Immunolocalization of Odorant Binding and Chemosensory Proteins from an Ectoparasitoid Scleroderma guani (Hymenoptera: Bethylidae)
The three-dimensional structures of two odorant binding proteins (OBPs) and one chemosensory protein (CSP) from a polyphagous ectoparasitoid Scleroderma guani (Hymenoptera: Bethylidae) were resolved bioinformatically. The results show that both SguaOBP1 and OBP2 are classic OBPs, whereas SguaCSP1 belongs to non-classic CSPs which are considered as the "Plus-C" CSP in this report. The structural...
متن کاملImmunolocalization of odorant-binding proteins in noctuid moths (Insecta, Lepidoptera).
Odorant-binding proteins were studied in the noctuid moths Agrotis segetum, Autographa gamma, Helicoverpa armigera, Heliothis virescens and Spodoptera littoralis using antisera raised against the pheromone-binding protein (PBP) and general odorant-binding protein 2 (GOBP2) of Antheraea polyphemus (Saturniidae). Proteins immunoreacting with these antisera were only found on the antennae and PBP ...
متن کاملbiological effects of saponin components extracted from sugar beet (beta vulgaris l.) leaf on spotted alfalfa aphid (therioaphis maculate buckten)
in this study, the biological effects of sugar beet leaf saponins on spotted alfalfa aphid was evaluated using thin layer chromatography. after saponin extraction from the leaf, three saponin concentrations together with a diet lacking saponin (control) were fed to aphids in five replications. the aphids’ survival and fertility were evaluated and analysed. results not only showed fertility impa...
متن کاملA large family of divergent Drosophila odorant-binding proteins expressed in gustatory and olfactory sensilla.
We identified a large family of putative odorant-binding protein (OBP) genes in the genome of Drosophila melanogaster. Some of these genes are present in large clusters in the genome. Most members are expressed in various taste organs, including gustatory sensilla in the labellum, the pharyngeal labral sense organ, dorsal and ventral cibarial organs, as well as taste bristles located on the win...
