Pressure–volume curves: revisiting the impact of negative turgor during cell collapse by literature review and simulations of cell ...
Our models were done on single cells and we think our single cells will collapse with less negative P t than sheets of palisade cells where some cell-to-cell contact can be expected. When cells are in contact with each other, they are less likely to collapse along the surfaces in common between them, because the P t values are approximately …
