| Outline of Final Research Achievements |
Preliminary genome sequencing and transgenic experiments of Nysius plebeius were performed in order to elucidate genetic and developmental basis of bacteriocyte-associated symbiosis independently evolved in small groups of heteropteran insects. With illumina-based paired end and mate pair library sequencing and de novo assembly using Platanus, we have generated genome scaffolds nearly full length of the insect genome as well as identifying immunity related genes and nutritional inter-dependence between the host and symbiont. On the other hand, new manual methods were established for injecting various foreign nucleic acids such as plasmid, mRNA and gRNA into early embryos of N. plebeius, although I have not succeeded in obtaining any transgenic or knockout lines so far. The study will continue based on these genetic and experimental resources for understanding the evolutionary basis of bacteriocyte in N. plebeius.
