Abstract
Panax notoginseng are attacked by several pathogens that cause root rot disease. Under pathogen infection, PR proteins accumulate to protect plants and enhance systemic acquired resistance. Studies have shown that PR genes in P. notoginseng are crucial for root rot resistance. However, genome-wide identification of PR genes in P. notoginseng remains limited. We identified 152 PR genes from the PR1, PR2, PR3, PR4, PR5, PR10, PR12, PR15, and PR17 families through conserved domain analysis. Transcriptomic and weighted gene co-expression network analysis revealed that PR genes play a crucial role in defense against Ilyonectria destructans infection. Furthermore, nine of these genes were consistently upregulated after infection and exhibited distinct expression patterns following treatments with salicylic acid and methyl jasmonate. PnPR4 was significantly upregulated after I. destructans infection, as well as after salicylic acid and methyl jasmonate treatments. When expressed in tobacco, PnPR4 enhanced resistance to Fusarium oxysporum . This suggests that PnPR4 confers broad-spectrum resistance in P. notoginseng , playing a key role in defense against root rot pathogens.
