Gene Editing Improves Biotic and Abiotic Stress Reponse of Tomato
January 17, 2024| |
A study published in Frontiers in Plant Science shows that editing the SlHyPRP1 and SlDEA1 genes of tomato improves its biotic and abiotic stress responses. This study has evaluated the drought, salinity, bacterial leaf spot, and bacterial wilt tolerance response of tomatoes.
Tomato has long been an essential crop in different regions and countries worldwide. However, the production of tomatoes has also faced various challenges related to the different stresses of plants. Previous studies have shown the role of SlHyPRP1 and SlDEA1 genes in response to stresses on tomatoes. Hence, the researchers used CRISPR-Cas9 genome editing technology to improve the stress tolerance of tomatoes.
The edited plants showed higher chlorophyll and proline content levels under abiotic stress conditions. Reactive oxygen species (ROS) accumulation and cell death count per total area of leaves and roots are also reduced under biotic stresses with the edited plants. The results of this study accelerate current research in developing crop varieties that can withstand stresses caused by climate change.
