AI Article Synopsis
- Research shows that plants with natural pest and disease resistance can enhance sustainable agriculture.
- A wild relative of the potato has been studied, uncovering how glycoalkaloids help in plant immunity by combating pests like the Colorado potato beetle.
- Discovering the structure and function of these natural defense compounds could lead to better methods for using them in food production sustainability.
Article Abstract
Plants with innate disease and pest resistance can contribute to more sustainable agriculture. Natural defence compounds produced by plants have the potential to provide a general protective effect against pathogens and pests, but they are not a primary target in resistance breeding. Here, we identified a wild relative of potato, , that provides us with unique insight in the role of glycoalkaloids in plant immunity. We cloned two atypical resistance genes that provide resistance to and Colorado potato beetle through the production of tetraose steroidal glycoalkaloids (SGA). Moreover, we provide in vitro evidence to show that these compounds have potential against a range of different (potato pathogenic) fungi. This research links structural variation in SGAs to resistance against potato diseases and pests. Further research on the biosynthesis of plant defence compounds in different tissues, their toxicity, and the mechanisms for detoxification, can aid the effective use of such compounds to improve sustainability of our food production.
