DREB transcription factor group is related to responses of plants to abiotic
stresses including drought. In a study conducted by Vietnamese scientists,
the ZmDREB2A transgenic maize lines at the seedling stage were evaluated for
drought resistance and biochemical characteristics.
Results showed that the survival rate of ZmDREB2A lines were 2.5 times
higher than wild type plants in artificial drought tests. Morphological
characteristics also showed the root length of ZmDREB2A lines were 21-28%
higher than that of control groups, which indicates ZmDREB2A lines could
suffer drought better. Moreover, the chlorophyll concentration of ZmDREB2A
lines was 10% higher than the wild type in drought condition. Other
parameters such as proline and nonstructural carbohydrate accumulation of
the transgenic lines were higher as compared to control groups.
