Better Tomatoes! Gene Introgression for Improving Fruit Quality
University of California System: University of California, Davis - UC Davis
posted on 11/04/2011
Researchers at the University of California, Davis have developed methods for improving fruit quality by introgressing genes encoding specific transcription factors into the plant.
Suggested Uses
Useful for commercial varieties of tomato.
Advantages
- Improved fruit quality in plants
- Increased level of soluble solids and/or sugars
- Increased levels of starch
- Standard breeding methods can be used
- Any standard method of screening for desired plants can be used
Detailed Description
Fruit chloroplasts are an essential element of the process required for fruit development. Studies suggest that fruit chloroplasts may contribute to the overall accumulation of starch and sugars by green fruit, thus contributing to the quality of the fruit when it ripens.
UC Davis researchers have identified the role of specific transcription factors in fleshy green fruit development and a method for preparing a plant with improved fruit quality. The introgression of select genes, which code for specific transcription factors, into the plant leads to their expression in the green fruit of the plant. Increased chloroplast biogenesis in the fruit occurs as a result of this method and thus the ripe fruit exhibit enhanced quality characteristics.
The trait should improve the flavor of fresh tomatoes and increase the processing efficiency and quality of processed tomatoes.
