It is intriguing how the turgor in the single-cell fibre is maintained and regulated.
Increases in embryo osmotic potential and in the turgor yield thresholds of both the radicle and the endosperm/pericarp envelope contributed to this change.
This, together with increases in tissue elasticity, had reduced the leaf water potential at which turgor loss occurred.
Affected cells are characterized by loss of turgor and lack of distinguishable organelles.
The loosening reduces the turgor pressure and establishes a water potential gradient across the cell membrane.
Asterisk: space between plasma membrane and cell wall due to turgor loss.
Reduction of embryo expansion by turgor limitation is one of the most direct.
The transgenic seedlings were only marginally affected over the 7-h air-drying period and after rehydration, they fully recovered turgor and recommenced growth.
