. Description of possible mechanisms of growth reduction
under drought stress. Under drought stress conditions, cell elongation
in higher plants is inhibited by reduced turgor pressure. Reduced water
uptake results in a decrease in tissue water contents. As a result,
turgor is lost. Likewise, drought stress also trims down the photoassimilation
and metabolites required for cell division. As a consequence,
impaired mitosis, cell elongation and expansion result in reduced
growth.
