| Abstract: |
| This paper reviewed the function of 68 drought-tolerant genes reported that could enhance the osmotic accumulation, detoxification and antioxidant, bio-molecule. The results showed that the function of transcription factor mainly by activating or inhibiting the expression of downstream drought genes; osmotic genes mainly maintained cell inside and outside osmotic balance; detoxification and antioxidant genes mainly eliminated the accumulation of reactive oxygen species; the genes involved in biological macromolecular synthesis can produce some adversity protein and enhanced crop resistance. In addition, existing problems are listed in order to provide a theoretical basis for the future in arid and semi-arid areas autopolyploid potato breeding drought-resistant crops. |
