Research Abstract

We established techniques of genetic modification (transgenesis and targeted mutagenesis) in the cricket Gryllus bimaculatus, of which the modes of oogenesis and embryogenesis differ from those of Drosophila. Using the transgenic cricket system, we investigated cell behaviors during early embryogenesis via live imaging of fluorescently labeled embryonic cells/nuclei and revealed very dynamic features of blastoderm cells. Furthermore, results from our live imaging analysis of RNAi-treated embryos suggested that the presumptive embryonic cells are regionally specified by genes such as orthodenticle before the dynamic cell movement in late blastoderm stages.
