Microspore-derived embryogenesis is of scientific interest in various respects: it constitutes a powerful model system to investigate induction of embryogenesis and early embryonic development. In contrast to zygotic embryogenesis, all developmental stages are freely accessable

During this pretreatment, microspores change into cells that are called embryogenic microspores
