Special Issue Information

Dear Colleagues,

Plant disease is one of the most destructive stresses which causes severe damages on the growth, development, and yields of almost the entire Plantae all over the world. Many studies have focused on plant pathogens in regard to their virulence, recognition, and long-lasting interaction with plant defense systems, while the potential strategies to prevent them remain to be found. Therefore, new strategies for controlling plant disease are urgently needed. This Special Issue aims to offer an update on recent progress in different approaches to phytopathogen resistance and selected strategies for disease resistance of plants with new tools in breeding and planting patterns. Potential topics include but are not limited to: 1. plant–pathogen interactions; 2. genome editing for disease resistance; 3. mining and characterization of pathogen effectors; 4. interaction between planting patterns and plant diseases; 5. localization and application of resistance genes; 6. role of biocontrol agents in pathogen resistance; 7. future perspectives for disease-resistance breeding.

Black scurf disease on potato caused by Rhizoctonia solani AG3 occurs worldwide and is difficult to control. The use of potato cultivars resistant to black scurf disease could be part of an integrated control strategy. Currently, the degree of resistance is based on symptom assessment in the field, but molecular measures could provide a more efficient screening method. We hypothesized that the degree of field resistance to black scurf disease in potato cultivars is associated with defense-related gene expression levels and salicylic acid (SA) concentration. Cultivars with a moderate and severe appearance of disease symptoms on tubers were selected and cultivated in the same field. In addition, experiments were conducted under controlled conditions in an axenic in vitro culture and in a sand culture to analyze the constitutive expression of defense-related genes and SA concentration. The more resistant cultivars did not show significantly higher constitutive expression levels of defense-related genes. Moreover, the level of free SA was increased in the more resistant cultivars only in the roots of the plantlets grown in the sand culture. These results indicate that neither expression levels of defense-related genes nor the amount of SA in potato plants can be used as reliable predictors of the field resistance of potato genotypes to black scurf disease.
