Improvement of abiotic stress tolerance of selected ornamental plants by the expression of transcription factors
Project
Project code: 2814101706
Contract period: 01.02.2007
- 31.01.2010
Budget: 279,549 Euro
Purpose of research: Experimental development
Plant stress tolerance is of increasing importance in plant breeding to face the challenges of a changing environment. Since abiotic stress tolerance is a complex trait which is not achievable in short time by conventional breeding, biotechnological methods can help to solve the problem. In the framework of the project, it will be tested whether stress tolerance in ornamental plants can be improved by overexpression of transcription factors. Transcription factors are regulatory genes and the resulting proteins can activate a lot of other genes which finally realize the stress tolerance reaction. Selected transcription factor genes shall be introduced in the ornamental species Petunia hybrida and the resulting transgenic plants will be analyzed for drought and chilling tolerance. If the overexpression of the selected transcription factors leads to a remarkable, i.e. commercially utilizable improvement of the drought and/or chilling tolerance, we will introduce this method in the practical cultivar development program. The newly generated cultivars finally shall be produced and commercialized like conventionally bred plant cultivars.
