Lithium decreases cold-induced microtubule depolymerization in mesophyll cells of spinach.

abstract：:Stationary volume fluxes through living and denatured parenchyma slices of the potato (Solanum tuberosum L.) storage organ were studied to estimate the hydraulic conductivity of the cell wall and to evaluate the significance of water transport through protoplasts, cell walls, and intercellular spaces.
