Transcription of zeaxanthin epoxidase chloroplastic (ZEP, Solyc02g090890), xanthoxin dehydrogenase (XDH, Solyc04g071960), and violaxanthin de-epoxidase (VDE, Solyc04g050930) were down-regulated by DC3000 infection, while ZEP and XDH were up-regulated by RL treatment. Here, XDH is linked to infection.
