ITRAQ-based proteomic profiling of salt-tolerant and salt-sensitive potato (<i>Solanum tuberosum</i>) cultivars under salinity stress.

ABSTRACT:

Introduction

Soil salinity represents a significant abiotic stress factor that adversely affects potato yield and quality. Elucidating the molecular mechanisms underlying salt tolerance is crucial for the development of resilient cultivars. This study examines the proteomic responses of salt-tolerant (M5008) and salt-sensitive (D516) potato cultivars under saline conditions.

Methods

A quantitative iTRAQ-based proteomic approach was utilized to analyze protein expression profiles in the roots of both cultivars exposed to 150 mM NaCl stress. Bioinformatics analyses-including Gene Ontology (GO) annotation, Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment, and protein-protein interaction (PPI) network construction-were performed. Key results were further validat
