"Seeds evolved when plants retained the female spores inside the parent tissue. The growth of the spores was accommodated by removing part of the nucellus, the maternal tissue responsible for female meiosis. Here, we demonstrate that modification of galacturonic acid polymers in the cell wall leads to nucellus cell death and eventual elimination. This work highlights the crucial contribution of extracellular polysaccharides to the development of multicellular organisms."
