Transcript profiles of genes involved in the MAPK pathway in Pst and defense-related genes in transgenic wheat plants L65 and L91. A, Transcript abundance of MAPK pathway-related genes in Pst decreases except for PsKPP2. Wheat leaves were sampled at 3 and 10 dpi with Pst. Data were normalized to the PsEF-1 expression level, and the CK-10d control was set to 1. B, Transcript abundance of pathogenesis-related proteins or defense-related genes increase in transgenic wheat plants L65 and L91 at 3 and 10 dpi. The data were normalized to the TaEF-1 expression level, and the CK-10d control was set to 1. Values represent the means ± se of three independent samples. PsKPP4, MAP kinase kinase kinase; PsFUZ7, MAP kinase kinase; PsKPP2, PsKPP6, and PsCRK1, MAP kinase; TaPR1, pathogenesis-related protein 1; TaPR2, β-1,3-glucanase; TaPAL, Phe ammonia lyase; TaAPX, ascorbate peroxidase; TaNOX, NADPH oxidase; TaSOD, superoxide dismutase; TaPOD, peroxidase; TaCAT2, catalase 2; TaCAT1, catalase 1.
