Database Research Summaries2018 Using Pseudomonas syringae effectors to discover and manipulate soybean immunity components
Research Focus
The focus of this project is to use pseudomonas syringae effectors to discover and manipulate soybean immunity components.
Objectives
- Identify soybean targets of type III effectors from the soybean pathogen P. syringae pv. Glycinea.
- Evaluate the importance of these targets to soybean immunity.
- Explore the extent that these targets can be manipulated to produce soybean
plants with improve resistance to biotic stress.
Results
- Plants are more resistant to the bacterial pathogen Pseudomonas syringae in the greenhouse and have a similar yield to wild type soybean in the field. Therefore, the expression of GRP7 does not reduce yield. Work will continue with these transgenic plants to determine if they are more resistant to other pathogens such as viral, fungal, or oomycete pathogens.
- Objective two continues to be a work in progress. Several new targets for P.syringae pv glycinea LN10 type III effectors have been identified. These projects take a long time to develop but there is consistent progress. It is quite likely that several of these potential targets are new components of soybean immunity.
Importance
- This project will discover components of the soybean immune system and it may deliver engineered soybean plants that possess increased resistance to microbial pathogens.
- This project should benefit Nebraska soybean farmers because it may result in soybean plants less susceptible to important soybean diseases.
