Higher turgor pressure

WebTurgor Pressure. Turgor pressure is an important feature of growing hyphae, in the sense that the cell is always at risk of rupturing if its surface is damaged (see Woronin bodies … WebOne significant function of the turgor pressure is to promote cell volume expansion (Kazuyuki et al., 1997), and the higher the turgor pressure is, the larger the leaf expansion will be (Liu et al., 2002). The magnitude of turgor pressure is determined by water potential and osmotic potential.

WebMore recent measurements indicate a turgor pressure for E. coli as low as ∼ 0.3 atm (primary source Deng et al., 2011). The higher turgor of Gram-positive bacteria must reflect a higher osmolyte concentration (e.g. K+ and counter ions) and consequently it will take a larger osmotic upshift to plasmolyse Gram-positive bacteria than Gram-negative cells.
