We investigated the mechanisms of action of selenium nanoparticles obtained by laser ablation for their use as an abiogenic elicitor of tomato resistance to parasitic nematodes. Selenium nanoparticles induced systemic resistance of tomatoes to the root-knot nematode, stimulated plant growth and development, was involved in the PR-6 gene expression in the roots and leaves of plants subjected to invasion, and increased the activity of proteinase inhibitors (markers of systemic resistance of plants to infection). Exogenous treatment of plants with solutions of selenium nanoparticles reduced the invasion of plants by affecting the morphological and physiological parameters of the parasites in the roots.
我们研究了通过激光烧蚀获得的硒纳米颗粒作为番茄对寄生线虫抗性的非生物诱导剂的作用机制。硒纳米颗粒诱导番茄对根结线虫产生系统抗性，刺激植物生长发育，参与受侵袭植物根和叶中PR-6基因的表达，并提高蛋白酶抑制剂的活性（植物对感染的系统抗性标志物）。用硒纳米颗粒溶液对植物进行外源处理，通过影响根中寄生虫的形态和生理参数，减少了植物的侵染。
