Study of the root-knot nematode infection mechanism using a model tomato, Micro-Tom

为了分析寄生根结线虫侵染寄主植物的反应机制，我们利用乙烯不敏感的共生基因突变系和共生基因敲除系，对一个矮生模式番茄品种进行了侵染试验。微型汤姆。结果表明，乙烯不敏感品系的卵块形成受到抑制，抑制程度与不敏感程度呈正相关。在共生基因敲除系中，根结线虫的侵染受到抑制。

To analyze the host plant response mechanism related to the parasitic root-knot nematode infection, we performed the infection assay using ethylene-insensitive mutant lines and knockdown lines of symbiosis genes, of a dwarf model tomato cv. Micro-Tom. The result indicated that the egg mass formation was suppressed in the ethylene-insensitive lines with the suppression level positively linked to the degree of insensitivity. It was also shown that the root-knot nematode infection was suppressed in the knockdown lines of symbiosis genes.
