Article Synopsis
- Globodera rostochiensis is a significant potato pathogen that interacts with host plant roots, with commercial varieties relying on specific resistance genes (R genes) from wild relatives and Andean native potatoes.
- Research on South American Solanum phureja accessions shows that resistant genotypes trigger an active stress response, including gene activation, tissue regeneration, and hypersensitive responses when attacked by G. rostochiensis.
- The study highlights the importance of analyzing gene expression changes in S. phureja to understand resistance mechanisms and suggests that de novo transcriptome assembly can identify new resistance traits.
Background: Net blotch caused by Pyrenophra teres f. teres is a major foliar disease of barley. Infection can result in significant yield losses of susceptible cultivars of up to 40%.

Article Synopsis
- * A study comparing the root transcriptomes of potato genotypes revealed differentially expressed genes related to resistance against a specific nematode, but limited annotations made it difficult to compile a clear list of candidate R genes.
- * Integrating transcriptomic analysis with data on certain potato genes improved candidate gene identification, suggesting that this combined approach could expedite the discovery of potato R genes for further research and breeding efforts.
Background: Spot blotch, caused by Cochliobolus sativus, is one of the most widespread and harmful diseases in barley. Identification of genetic loci associated with resistance to C. sativus is of importance for future marker-assisted selection.
