| Outline of Final Research Achievements |
"Host web manipulation" is one of host behavioral manipulations performed by spider-ectoparasitoids. I undertook a project to elucidate the molecular mechanism of this phenomenon by means of RNA-seq analysis using a parasitoid known to exploit an innate "resting-web" building behavior of its host spider for manipulation.
I compared gene expression dynamics of manipulated spiders with normal orb-web building individuals and resting-web building individuals. As a result, I discovered a certain isoform of spider silk that was highly expressed in the phases of both resting-web building and being manipulated. This isoform is expected to be a key-gene directly getting involved with host web manipulation that induced by physiological interference of the parasitoid.
