Outline of Final Research Achievements |
Although thermoregulation is one of the essential homeostatic processes that maintain animal’s functional capacities in fluctuating thermal environments, its underlying molecular mechanisms still remain enigma. To identify molecules involved in thermoregulation, we have conducted mutagenesis and screens for mutants with altered temperature preference in Drosophila melanogaster. During the course of this study, we found that the thermoregulatory behavior of Drosophila is strongly affected by the presence of commensal gut bacteria. In this study, we have identified, 1) Gut microbiome present in the different strains of Drosophila, using next generation sequencer, 2) Species of bacteria that affect the thermoregulatory behavior, 3) Novel molecular species of lipids produced by the commensal bacteria using liquid chromatography-tandem mass spectrometry.
