NPR1 and infection: An 1.28 fold increase in SAGT transcripts in transgenics compared to the untransformed plants at 1day after infection suggest that soon after infection, SAGT levels were slightly elevated by the transgene- BjNPR1. NPR1 mutants of Arabidopsis exhibited reduced induction of AtSAGT1 at 16 h after infection with Pseudomonas syringae as compared to the wild-type plants, implying NPR1 mediated partial up-regulation and immediate early induction of AtSAGT1[39].
