The shoot apical meristem (SAM) is a small population of stem cells that continuously generates organs and tissues. Meristem function and maintenance involve a complex network of regulatory genes and signalling molecules. A major downstream target of this network is the cell wall, which is a local determinant for both growth rates and growth directions. However, the precise link between cell wall structure and molecular regulation is not well understood.
To address this issue, we have developed a computational and experimental pipeline, aimed at expressing gene function in terms of quantified, geometrical changes in tissue shape. In parallel we have started to provide a more mechanistic view of shape control. We have provided evidence for a model where molecular networks impact on both cell wall anisotropy and synthesis thus causing the rapid outgrowth of organs at particular locations.
