| Outline of Final Research Achievements |
Host plant recognition-concerning taste detection system was attempted to be cleared. First, a member of taste receptors, BmGrs which is expressing in a taste sensing cell of epipharyngeal sensillum in the labrum of Bombyx mori larvae was attempted to be cleared. A neural cell cluster of epipharyngeal sensillum was obtained using glass-capillary and single cell was dissected from it by laser capture microdissection (LCM). RT-PCT suggested that this cell expressed 6 kinds of BmGrs including BmGr10 and they were considered to construct inositol receiving system. Ca2+ indicators, GCaMP co-expressing system and Xenopus oocyte expressing system connected to two-electrode voltage clamp were used to determine the ligand of BmGr10. From these, inositol was demonstrated to be a ligand of BmGr10.
