Plantago lanceolata Transcriptome or Gene expression. Plantago lanceolata

investigate how Plantago genotype affects infection and what are the similarities and differences of susceptible and resistant genotypes in response to the same pathogen, we sequenced the transcriptomes of five different Plantago lanceolata genotypes in response to inoculation by the same strain of obligate fungal pathogen Podosphaera plantaginis. The gene expression data showed highly varying responses, with each plant genotype having a unique gene expression profile in response to the pathogen, regardless of the resulting resistance phenotype. Our results demonstrate that phenotypic resistance diversity results from crosstalk between different defense mechanisms. In conclusion, characterizing the architecture of resistance in natural host populations may shed unprecedented light on the potential of evolution to generate a variation.为探究车前属（Plantago）基因型如何影响病原菌侵染过程，以及感病与抗病基因型在响应同一病原菌时的异同，我们对5种不同长叶车前（Plantago lanceolata）基因型在被同一专性寄生真菌病原菌车前单囊壳（Podosphaera plantaginis）菌株接种后的转录组（transcriptome）进行了测序。基因表达数据显示，宿主的转录响应差异显著：无论最终表现出的抗病表型如何，每种车前基因型均拥有独特的响应病原菌的基因表达谱。本研究结果证实，表型抗病多样性源自不同防御机制间的信号串扰。综上，解析自然宿主种群的抗病机制架构，或将为理解进化产生遗传变异的潜在潜力提供前所未有的洞见。
