Summary Nature exhibits organs of various shapes and forms, ranging from smooth to undulated morphologies. How cells coordinate their growth to produce smoothly shaped leaves and leaf-like organs such as sepals remain unclear. We identified a mutant, as2-7D, that exhibits ectopic expression of ASYMMETRIC LEAVES 2 (AS2)...

Plant organ shape emerges from coordinated growth between adjacent tissues and from the mechanical conflicts that arise when growth rates differ. In Arabidopsis, the gynoecium, the female reproductive organ that develops into the fruit, consists of fast-growing valves flanking the slowly expanding replum, a medial doma...

The growth and division of cells in plant leaves is highly dynamic in time and space, even though cells cannot move relative to their neighbors. Thus, organ shape must emerge from carefully coordinated growth, especially in leaves that remain relatively flat as they grow. Here we explored the phenotype of the jagged an...

Measurements of cell geometry, growth of marked cell clones, tissue-specific expression, and subcellular localization all support the idea that these IQD proteins reduce longitudinal cell divisions in the RZ, limiting the build-up of vertical cell files in inner tissues and the concomitant radial growth of the stem.
