Abstract
The in vitro fertilization system of maize is the well characterized model system for the fertilization process and early zygotic embryogenesis of higher plants. Application of molecular methods to the in vitro fertilization system led to the isolation of new genes and uncovered specific expression patterns of cell cycle regulators. Recent studies showed that expression of transgenes is possible in gametes and zygotes, thus transgenic approaches might offer an opportunity to unravel the roles of genes during fertilization and early development. The competence of gametes and zygotes to express transgenes will also enable the expression of GFP based reporter genes for the visualization of subcellular components in these cells in vivo. This review focuses on the data concerning the expression of transgenes in gametes and zygotes and describes some examples of recent developments in transgenic technology illustrating the emerging possibilities in experimental design by combining this technology with in vitro fertilization.
