Role of tissue mechanics in regulating seed growth

Coordination of growth in multicellular organisms requires the integration of signals that are received from both intracellular cues and tissue-level cellular interactions. In particular, mechano-responsive signalling pathways are now emerging as prominent controllers of growth coordination at the organ level. While the underlying genetic networks that are regulated by these pathways have been well characterised in animals, they are largely unknown in plants, limiting our understanding of plant development. The over-arching goal of this PhD project is to understand how mechanical forces determine plant shape using the Arabidopsis seed as model system. The project is part of newly established collaboration between the Golz (UoM) and Ingram (CNRS, ENS-Lyon) groups and will involve travel to and collaboration with the French group to investigate the genetic pathways controlling the mechanical properties of the seed coat and their implication in the control of seed size.
