Drought-resistant plants

The use of plants from extreme environments Wild plants from extreme environments may possess genes and gene combinations which confer stress tolerance. We must realise, however, that many of their characteristics, e.g. leaf pubescence and succulence in drought-resistant plants, are incompatible with the high yield potential required for crop plants. In addition, most of these species contain compounds such as phenolics and mucilages which interfere with conventional molecular biology techniques.

Plant type can determine water requirements. Drought-resistant plants, adapted to surviving extremely dry conditions, positively thrive where water is short, and may fail if the soil is too wet. The location of the plant also has a bearing on its watering requirements. Plants in containers, for example, rely on you, the gardener, for their supply. Plants in "rain-shadow" locations—such as next to a house, wall or fence, where the soil is sheltered and thus receives less rain—are more likely to be short of water. 

Simmondsia chinensis seed oil. Jojoba oil is another source of C20 and C22 compounds that has already been developed as a marketable product but in limited supply (195). It is produced by a drought-resistant plant that withstands desert heat.

Therefore drought resistance (in terms of plant production) is positively associated with T or Ea, m or WUE and HI under drought stress. A simple simulation using (1) would indicate that a given increase in Tor m is most effective towards plant production when water stress is not severe.
