Desiccation In Plants. Hydrated leaves of the resurrection grass sporobolus elongatus are not desiccation tolerant (dt), but moderate to severe drought stress can induce their dt with the leaves remain attach to drying intact plants. An exception is a small group of vascular angiosperm plants, termed resurrection plants. Namely avoidance, resistance, or tolerance to desiccation (levitt 1980).some plants (e.g. Pharmaceutical medicines and supplements are produced in a dry environment.

Desiccation of plants is often lethal but is tolerated by the majority of seeds and by vegetative tissues of only a small number of land plants. Plant water status, photosynthetic rates, net carbon gain, and efficiency of photosystem ii (psii) were assayed to evaluate tissue desiccation, basic metabolic processes and plant recovery. It requires a coordinated series of events during dehydration that are associated with preventing oxidative damage and maintaining the native structure of macromolecules and membranes. Dt requires the presence of protective proteins, specific carbohydrates, restructuring of membrane lipids, and regulatory mechanisms directing a dedicated gene expression program. In the green vegetative tissues of mosses, ferns and angiosperm resurrection plants, it is often a slight dehydration that triggers gene expression associated with desiccation tolerance. Desiccation of plants is often lethal but is tolerated by the majority of seeds and by vegetative tissues of only a small number of land plants.
The preferential hydration of macromolecules is essential when there is still bulk water present, but replacement by sugars becomes important upon further drying.

They have evolved unique mechanisms of desiccation tolerance and thus can tolerate severe water loss, and mostly adjust their water content with the relative humidity in the environment.

Abscisic acid (aba) plays a critical role in regulating plant responses to dehydration and in the acquisition of desiccation tolerance. Why anhydrobiotic plants should rely upon sucrose and not trehalose is unknown. Desiccation tolerance (dt), the ability to recover from an almost complete loss of protoplasmic water, is a phenomenon that is rare in vegetative tissues but common in the reproductive structures of green plants.
