Sodium alginate enhances defense responses of <i>Pinus sylvestris</i> var. <i>mongolica</i> against <i>Bursaphelenchus xylophilus</i> by regulating <i>chs</i> genes and flavonoid metabolites
The expression of chs genes plays a critical role in the defense of P. sylvestris var. mongolica against PWN infection. Spraying 100 mg/L NaAlg solution before PWN infection activates chs genes in P. sylvestris var. mongolica, regulating the levels of L-tyrosine, phloretin, chrysoeriol, and p-coumaryl alcohol to enhance self-resistance against PWN, thereby delaying the progression of PWD in P. sylvestris var. mongolica. © 2025 Society of Chemical Industry.
