Drought Tolerance

Drought tolerance refers to the degree to which a Plant is adapted to Arid or Drought conditions. Desiccation tolerance is an extreme degree of Drought tolerance. Plants naturally adapted to dry conditions are called xerophytes.

Drought tolerant plants typically make use of either C4 carbon fixation or Crassulacean acid metabolism to fix carbon during Photosynthesis. Both are improvements over the more common but more basal C3 pathway in that they are more Energy efficient. CAM is particularly good for arid conditions because Carbon dioxide can be taken up at night, allowing the stomata to stay closed during the Heat of day and thus reducing Water loss.
