From: Comparative transcriptome analysis of grapevine in response to copper stress
Substitution relation between Cu-Zn superoxide dismutase (Cu-Zn SOD) and Fe superoxide dismutase (Fe SOD) depending on Cu bioavailability in grapevine.
Cu-Zn SOD is the predominant SOD within the chloroplast during Cu-replete conditions, whereas it is substituted by Fe-SOD upon Cu limitation. Cu proteins are represented in blue, while Fe proteins are in red. Solid and dotted lines represent, respectively, the main and minor Cu delivery pathways under Cu deficiency. PC, plastocyanin; SOD, superoxide dismutase.
