Acidic cell elongation drives cell differentiation in the Arabidopsis root.

ABSTRACT: In multicellular systems, the control of cell size is fundamental in regulating the development and growth of the different organs and of the whole organism. In most systems, major changes in cell size can be observed during differentiation processes where cells change their volume to adapt their shape to their final function. How relevant changes in cell volume are in driving the differentiation program is a long-standing fundamental question in developmental biology. In the Arabidopsis root meristem, characteristic changes in the size of the distal meristematic cells identify cells that initiated the differentiation program. Here, we show that changes in cell size are essential for the initial steps of cell differentiation and that these changes depend on the concomitant activatio
