Growth dynamics of the Arabidopsis fruit is mediated by cell expansion

Abstract: Significance Fruit are the harvested product of many crops and their importance in yield and global food supply is indisputable. Fruit size (growth), shape, and seed dispersal strategies vary markedly in different plant species, and their clear understanding should facilitate improvements in agricultural production. Here we have mapped the cellular growth of the Arabidopsis fruit (seedpod) after fertilization, and also delineated and modeled how seed-derived signaling cascades impinge upon fruit elongation. We have found that fertilization is the developmental switch that transitions fruit from cell division to cell expansion, which is tightly synchronized with seed development inside the fruit. Our study lays the groundwork to facilitate strategies for crop engineering to further increase their agroeconomic value.
