Scholarcy highlights

  • Plants often encounter unfavorable environmental conditions because of their sessile lifestyle
  • Plants have evolved a series of mechanisms at the morphological, physiological, biochemical, cellular, and molecular levels to overcome water deficit or drought stress conditions
  • The drought resistance of plants can be divided into four basic types-drought avoidance, drought tolerance, drought escape, and drought recovery
  • Scientists have investigated the genetic and molecular mechanisms of drought resistance to enhance the drought resistance of various crops, and significant progress has been made with regard to drought avoidance and drought tolerance
  • With increasing knowledge to comprehensively decipher the complicated mechanisms of drought resistance in model plants, it still remains an enormous challenge to develop water-saving and drought-resistant crops to cope with the water shortage and increasing demand for food production in the future
