The onion fly, Delia antiqua (Meigen), is a pest specialized to the onion, Allium cepa L., and some other Allium plants. Host odorants play an important role in the attraction of D. antiqua adults and stimulation of oviposition in females. Odorant-binding proteins (OBPs) may serve as a first step in the perception of these chemical cues. In this study, to(More)
Insect odorant-binding proteins (OBPs) function in the perception of chemical cues such as pheromones and host-plant odors. Comparative genomic analysis has shown that OBP genes underwent the birth-and-death process through the evolution of Hexapoda, resulting in diverged OBP repertoires between distantly related species. On the other hand, comparisons(More)
AIMS The adhesion ability of Lactobacillus gasseri SBT2055 was investigated in vitro by searching for its adhesion molecules. METHODS AND RESULTS Lactobacillus gasseri SBT2055 showed adherence to host components, including two commercially available mucins, Caco-2 epithelial-like cells and the extracellular matrix molecule fibronectin (Fn). Its adhesion(More)
