Outline
To elucidate the proteomic response mechanism of potato to a pathogenic toxin Thaxtomin A (TA), causing common scab, this study was conducted using the potato cultivar Kexin 19 as the experimental material. Tandem Mass Tag (TMT)-based quantitative proteomics technology was employed to analyze the differential proteomes of potato leaves treated with the toxin and a control group. A total of 130 differentially expressed proteins (DEPs) were identified, including 80 up-regulated and 50 down-regulated. GO and KEGG enrichment analysis showed that the DEPs were significantly enriched in biological processes such as defense response, plant MAPK signaling pathway, S-adenosylmethionine biosynthesis, and protein processing in the endoplasmic reticulum. This reveals that the response of potato to the scab toxin involves a complex physiological and biochemical regulatory network. Through protein-protein interaction network analysis, the core protein M1ASG7 with the highest connectivity was screened out. Additionally, two up-regulated DEPs, M02PK2 and M1A0Y3, were found in its metabolic pathway, all of which are closely related to the regulation of cellular metabolism.
