Mechanisms of cellular expansion in plants
Abstract
Even though mankind highly depends on plant derived products, our insight into plant specific growth mechanisms is scarce. The plant vacuoles as well as the cell wall are key regulatory factors that jointly control cellular expansion. The process of cell elongation requires both the loosening of cell wall properties and increase in vacuolar volume in a well-orchestrated manner (Löfke et al., eLife 2015; Dünser and Kleine-Vehn, COPB 2015; Scheuring et al., PNAS 2016). However, a growth integrating mechanism, possibly coordinating molecular events in the cell wall and the vacuole, remain currently unknown. Here, we propose that changes in cell wall mechanics integrate vacuolar morphology. We intend to isolate likely cell wall sensors, required to integrate mechanical cues with vacuolar occupancy of the cell. The results of this PhD project might help to elucidate cellular growth control mechanisms contributing to overall plant growth and development.
