A plant embryo forms during seed development, as a single-celled zygote undergoes a pre-programmed pattern of cell division and differentiates into tissues and organs. A similar process continues during a plant's lifetime at the tips of its roots and shoots. Recently, Grossniklaus and colleagues reported that the maternal genome primarily controls gene expression patterns during early embryogenesis in Arabidopsis, as maternal factors repress paternal transcription though the chromatin siRNA pathway. A morph of early stages of embryo development in Arabidopsis thaliana. The morph is based on seven projection images of propidium iodide-stained seeds acquired by confocal laser scanning microscopy. The movie was generated with the Xmorph software. Video courtesy of Célia Baroux, John Runions, Ueli Grossniklaus, University of Zürich and Oxford Brookes University. Learn more in Autran et al.
