WNK2 and infection: To date, genome-wide identification of MAPK (Mitogen-activated protein kinase), MAPKK (Mitogen-activated protein kinase kinase), MAPKKK (Mitogen-activated protein kinase kinase kinase), and other gene families has been performed on the basis of these genomic data, and correlation analysis of the haplotype of the NADPH-cytochrome P450 reductase gene and infection ability has been performed [7,8].
