·有益的根际微生物在根定殖过程中可能具有相似的分子步骤。 为了验证这一假设，我们比较了蒺藜苜蓿。在被Glomus mosseae BEG12、荧光假单胞菌C7R12或苜蓿中华根瘤菌定殖或未定殖的根中的基因表达2011。·荧光假单胞菌C7R12在M. 蒺藜根和定殖根组织细胞间和细胞内的方式类似于先前描述的其他植物。·一组12个上调的菌根M的半定量逆转录酶聚合酶链反应。 接种荧光假单胞菌和S.苜蓿草。荧光假单胞菌定植激活了7个植物基因，而植物根系仅3个基因表达增加，5个基因表达下调。·这是第一份关于荧光假单胞菌和菌根真菌在根部诱导类似基因的报告，支持了这样的假设，即这些有益微生物在根部定植期间可能共享一些植物细胞程序。 与S.苜蓿草。
• Beneficial rhizosphere microorganisms may share similar molecular steps during root colonization. To test this hypothesis, we compared Medicago truncatula Gaertn. gene expression in roots colonized, or not colonized, by Glomus mosseae BEG12, Pseudomonas fluorescens C7R12 or Sinorhizobium meliloti 2011. • Pseudomonas fluorescens C7R12 formed colonies on the surface of M. truncatula roots and colonized root tissues intercellularly and intracellularly in a way similar to that previously described for other plants. • Semiquantitative reverse transcriptase polymerase chain reaction of a set of 12 mycorrhiza upregulated M. truncatula genes revealed different expression profiles in roots 3 weeks after inoculation with P. fluorescens or S. meliloti. Pseudomonas fluorescens colonization activated seven of the plant genes while nodulated root systems showed increased expression in only three genes and five appeared to be downregulated. • This first report of similar gene induction by a fluorescent pseudomonad and a mycorrhizal fungus in roots supports the hypothesis that some plant cell programmes may be shared during root colonization by these beneficial microorganisms. Less similarity existed in expression of the gene set with nodulation by S. meliloti.
