Sorghum downy mildew (SDM) caused by the oomycete, Peronosclerospora sorghi, is one of the destructive diseases that afflict maize. P. sorghi infects a susceptible host, hindering its growth and altering its morphology. To understand the molecular basis of the compatibility interaction between P. sorghi and maize, a comparative proteomic approach (2D-PAGE) was employed between the mock-inoculated (control) and SDM-inoculated leaves in the susceptible genotypes of maize (UMI79 and CM500). Seventeen spots showed a significant difference in the abundance of proteins in control and inoculated samples were further analyzed with MALDI-TOF/MS. | Proteomic analysis of a compatible interaction between sorghum downy mildew pathogen Peronosclerospora sorghi and Maize Zea mays L.
