Fig. 2. Genotype-specific regulation patterns of mitogen-activated protein kinases (MAPK) encoding genes in apple roots during Pythium ultimum infection.

Numbers on Y axis are the log₂FC values, which represent the expression changes by comparing those from P. ultimum infected tissues and mock-inoculated control tissues. The positive values indicate the upregulation due to pathogen infection, whereas the negative values represent the downregulated expression. Identified genes were listed on X axis by genotype and timepoint
