AI Technical Summary
Eucalyptus globulus grows under limited conditions in arid environments. Existing breeding methods are inefficient and lack key drought-resistant gene resources, making it difficult to quickly cultivate highly drought-resistant varieties.
The EgDREB2A gene, a drought-resistant transcription factor associated with Eucalyptus globulus, was cloned. The drought resistance of Eucalyptus globulus and other plants was improved through genetic engineering. A recombinant vector was constructed using the EgDREB2A gene and its encoded protein. The vector was introduced into Eucalyptus globulus cells via Agrobacterium-mediated transformation. After screening and culturing, plants with significantly better drought resistance than non-transgenic plants were obtained.
The goal is to rapidly cultivate new drought-resistant Eucalyptus varieties, improve survival rate and growth, reduce water consumption, mitigate economic losses caused by drought stress, and provide genetic resources and technical references for improving the drought resistance of other plants.
