is a soil-borne vascular pathogen that causes severe wilt symptoms in a wide range of plants. Co-culture of the fungus with roots for 24 h induces many changes in the gene expression profiles of both partners, even before defense-related phytohormone levels are induced in the plant. Both partners reprogram sugar and amino acid metabolism, activate genes for signal perception and transduction, and induce defense- and stress-responsive genes. Furthermore, analysis of expression profiles suggests a redirection from growth to defense. After 3 weeks, severe disease symptoms can be detected for wild-type plants while mutants impaired in jasmonate synthesis and perception perform much better. Thus, plant jasmonates have an important influence on the interaction, which is already visible at the mRNA level before hormone changes occur. The plant and fungal genes that rapidly respond to the presence of the partner might be crucial for early recognition steps and the future development of the interaction. Thus they are potential targets for the control of -induced wilt diseases.
是一种土传维管束病原体，可在多种植物中引起严重的枯萎症状。该真菌与根共培养24小时会在双方的基因表达谱中诱导许多变化，甚至在植物中诱导与防御相关的植物激素水平之前就已发生。双方都会重新编程糖和氨基酸代谢，激活信号感知和转导相关基因，并诱导防御和应激反应基因。此外，对表达谱的分析表明从生长向防御的转变。3周后，野生型植物可检测到严重的疾病症状，而茉莉酸合成和感知受损的突变体表现要好得多。因此，植物茉莉酸对这种相互作用有重要影响，这在激素变化发生之前的mRNA水平上就已可见。对伙伴存在迅速做出反应的植物和真菌基因可能对早期识别步骤和相互作用的未来发展至关重要。因此，它们是控制由……引起的枯萎病的潜在靶点。
