Comparative transcriptome analysis reveals key genes and signaling pathways mediated by salicylic acid in potato.

ABSTRACT:

Background

Salicylic acid (SA) is a key phytohormone involved in regulating plant growth, development, and immune responses. While its signaling roles have been extensively characterized in model species, the molecular mechanisms and SA-responsive genes in potato remain largely uncharacterized.

Objective

This study aims to elucidate the SA-mediated transcriptional network in potato by conducting a comparative transcriptomic analysis under treatments with exogenous SA and 1-aminobenzotriazole (ABT), a pan-selective cytochrome P450 inhibitor, that impairs enzymes required for salicylic acid (SA) biosynthesis.

Results

RNA-seq analysis identified 6,668 and 3,815 differentially expressed genes (DEGs) under SA and ABT treatments, respectively, with 1,759 DEGs displaying inv
