| Abstract: | s: In this paper, the relationship between drought stress and changes in crop root under low water potential are reviewed, these changes adapted to drought include the morphological characters of crop root, hydraulic lift, physiological metabolism, root cell wall extensibility and root cell wall proteins, etc. Furthermore, it is suggested that more researches should be concentrated on the genetic mechanism of the changes on the root developing and root growth characters against drought stress. |

| Keywords: | drought stress crop root morphological characters cell wall proteins |
