Canola zygotic embryo culture.

To further understand the events occurring during embryogenesis, it is imperative to have an experimental system. While somatic embryo is the system of choice due to the prolific number and success of protocols available, it is necessary to compare in vitro results with those in vivo. This process is often difficult due to the inaccessibility of the developing embryo and the complications of manipulating the embryo in vivo. The development of protocols that allow for manipulation and comparison of both somatic and zygotic embryos is key to elucidating the differences between the two types of embryos and determining if results observed using one system can be applied to the other. This chapter details a simple protocol for the culture of zygotic embryos of canola that allows for the processing of large numbers of embryos with little physical damage. Furthermore, this protocol allows for the experimental manipulation of zygotic embryos in vitro and comparisons to be made with a well-established microspore-derived embryo system.
