Although the stalk persists for several weeks until the embryo reaches at least 500 cells, proper embryogenesis requires connection to maternal tissue only during the first...

...Merijn Kerstens; Carla Galinha; Hugo Hofhuis; Michael Nodine; Renan Pardal; Ben Scheres; Viola Willemsen ABSTRACT Plants are dependent on divisions of stem cells to establish cell lineages required for growth. During embryogenesis, early division products are considered to be stem cells, whereas...

...Ioannis Theodorou; Bénédicte Charrier ABSTRACT In most organisms, 3D growth takes place at the onset of embryogenesis. In some brown algae, 3D growth occurs later in development, when the organism consists of several hundred cells. We studied the cellular events that take place when 3D growth...
