• 論文の詳細を見る

• It has been proposed that the suspensor has important roles in early embryogenesis in seed plants. However, the roles of the suspensor are not well understood, because the development of zygotic embryos normally occurs deep within both the endosperm and the maternal cells. In this paper, we report the development of an in vitro culture system to investigate the roles of the suspensor in the development of the embryo proper, using a somatic embryogenesis system with Japanese larch (Larix leptolepis GORDON). Our results indicate that the suspensor is essential for the normal development of somatic embryos of this species. This method provides a useful experimental system to investigate the interactions between the embryo proper and the suspensor.
