n plants, cell growth is controlled by positional information, yet the behavior of individual cells in an expanding tissue is often highly heterogeneous. The origin of this variability is still unclear. Using quantitative time-lapse imaging we determined the source and relevance of cellular growth variability in developing organs of Arabidopsis thaliana. We showed that cell-autonomous behavior of specialized cells is the main source of local growth variability in otherwise homogeneously growing tissue. Growth differences are buffered by the immediate neighbors of specialized cells to achieve robust organ development.
