Microbe-associated molecular pattern-triggered immunity (MTI) is an important component of the plant innate immunity response to invading pathogens. However, most of our knowledge of MTI comes from studies of model systems with relatively little work done with crop plants. In this work, we report on variation in both the microbe-associated molecular pattern-triggered oxidative burst and gene expression across four soybean (Glycine max) genotypes. Variation in MTI correlated with the level of pathogen resistance for each genotype. A quantitative trait locus analysis on these traits identified four loci that appeared to regulate gene expression during MTI in soybean. Likewise, we observed that both MTI variation and pathogen resistance were quantitatively inherited. The approach utilized in this study may have utility for identifying key resistance loci useful for developing improved soybean cultivars.
微生物相关分子模式触发的免疫（MTI）是植物对入侵病原体固有免疫反应的重要组成部分。然而，我们对 MTI 的大部分了解都来自于相对较少的作物研究模型系统。在这项工作中，我们报告了四个大豆（Glycine max）基因型中微生物相关分子模式触发的氧化爆发和基因表达的变化。MTI 的变化与每个基因型的病原体抗性水平相关。对这些性状的数量性状位点分析鉴定出了四个似乎在大豆 MTI 过程中调节基因表达的位点。同样，我们观察到 MTI 的变化和病原体的抗性都是数量遗传的。本研究中采用的方法可能有助于鉴定用于开发改良大豆品种的关键抗性基因座。
