Defence mechanisms against production of free radicals in cells of ‘resurrection’ plants

Extract
The ability of protoplasm to revive following severe water deficit is at its greatest in desiccation-tolerant or ‘resurrection’ plants. Boea hygroscopica is a resurrection plant that is able to survive air-dryness following slow dehydration (80% RH) in a physiological state called anabiosis (Schwab & Gaff 1990). However, this plant loses the ability to recover complete physiological activity following rapid water loss (0% RH).
The ability to recover complete physiological activity following repeated protoplasmic dehydration of fully differentiated tissues is an adaptation mechanism unique to resurrection plants.
