ENOX2 and infection: Twenty four hours after infection with Pst DC3000 (which expresses a genomic copy of AvrPto), and before the onset of cell death due to the recognition of HopQ1 (Wei et al., 2007), the genes encoding RIN4, TOM1, APP4, and APK2 were found to be significantly up-regulated, whereas APK1 expression levels dropped slightly over this time period.
