Genetic Engineering Improves Salt Tolerance in Wheat
February 26, 2025| |
A study published in GM Crops & Food showed the development of transgenic wheat plants that can withstand salt stress conditions. The findings of the study demonstrate a promising approach for improving salt tolerance in crops.
The researchers used genetic engineering to introduce MDAR1, a gene from Arabidopsis thaliana plant, to increase ascorbic acid (AsA) levels in wheat. The study developed six independent transgenic wheat lines expressing the MDAR1 gene through biolistic bombardment.
The results showed that the transgenic wheat plants showed a significant increase in AsA levels compared to non-transgenic lines and increased tolerance to salt stress (mm) in greenhouse conditions. Reactive oxygen species (ROS) concentrations were observed to be significantly lower in transgenic plants under control and salt stress conditions. The study concluded that AsA accumulation, driven by MDAR1, enhances the ability of wheat to withstand high salinity with improvement in growth characteristics.
