                   Abstract  Drought has become one of the key environmental factors limiting the development of agri⁃
               culture in China. Due to fixed growth， plants cannot actively escape from stress when external water factors
               change，  and  can  only  rely  on  their  own  mechanisms  to  resist  external  stress.  Therefore，  studies  on  plant
               drought  resistance  are  becoming  very  urgent.  This  article  reviewed  the  previous  researches  related  with
               plant drought tolerance. The focus was on exploring the classification of desiccation-tolerant plants， the re⁃
               sponse  mechanisms  of  their  morphological  structure，  physiological  and  molecular  level  during  dehydration
               and  rehydration  to  provide  new  ideas  for  mining  desiccation-tolerant  genes，  creating  desiccation-tolerant
               germplasm resources and breeding new desiccation-tolerant varieties.
