Comparative transcriptome analysis of sweet cherry (Prunus avium L.) cultivar 'Lapins' upon infection of Pseudomonas syringae pv. syringae

Bacterial canker caused by Pseudomonas syringae pv. syringae (Pss) is responsible for substantial loss to the production of sweet cherry in Chile. To date, the molecular mechanisms of Pss-sweet cherry interaction and the disease-related genes in the plant are poorly understood. In order to gain insight into these aspects, a transcriptomic analysis of sweet cherry cultivar 'Lapins' for differentially expressed genes in response to Pss inoculation was conducted. Three Pss strains, A1M3, A1M197 and 11116_b1, were inoculated in young twigs, and RNA was extracted from tissue samples at the inoculation site and distal sections.
