“…Their expression patterns underscore a tight linkage between metabolic pathways and pathogen response. The downregulation of ERF010 suggests a potential modulation of the ethylene signaling pathway in response to scab infection, prompting further exploration of its interplay with other hormonal pathways in plant immunity [48,49]. Baharudin's research highlighted ethylene's role in regulating plant responses post infection, including defensive actions and repair processes [50].…”

Potato scab, a global soil-borne disease caused by Streptomyces, is pivotal in developing resistant cultivars due to its complex resistance mechanisms. This study investigates the transcriptomic responses in potato to common scab using resistant variety CS10 and susceptible CS11 post S. scabie inoculation (0 d and 10 d, 12 cDNA libraries). Differential expression analysis identified 147 key DEGs (Differentially Expressed Genes) essential in disease recognition, signal transduction, and defense. GO (Gene Ontology) and KEGG (Kyoto Encyclopedia of Genes and Genomes) enrichment analyses revealed several significant metabolic pathways, such as ADP binding, heme binding, chloroplast thylakoid membrane, photosynthesis, glutathione metabolism, and homologous recombination, among others. Notably, the correlation between chloroplast pathways (GO:0019745) and photosynthesis (map00195) highlights photosynthesis’s role in potato scab response, while the oxygen transport (GO:0031408)-related glutathione metabolism pathway (map00480) emphasizes antioxidant defenses. Furthermore, three potential resistance genes were validated: Ethylene Response Factor ERF010 (LOC102589042), Disease Resistance Protein RPP13 (LOC102605863), and Cytochrome P450 83B1 (LOC102604056), demonstrating the linkage between metabolic pathways and pathogen response. These findings offer insights into potato’s molecular resistance mechanisms against potato scab, supporting the breeding of resistant varieties and comprehensive disease management, thus advancing sustainable agriculture.
