The acceptor availability at photosystem I and ABA control nuclear expression of 2-Cys peroxiredoxin-A in Arabidopsis thaliana.

The redox-regulated 2-Cys peroxiredoxin-A (2CPA) promoter, which drives expression of a dominant chloroplast antioxidant enzyme, responds to signals originating from the photosynthetic electron transport downstream of PSI. Modulation of CO(2)- and NO(3)(-) -reduction rates in reporter gene plants expressing glucuronidase under control of the Arabidopsis thaliana 2CPA promoter revealed that promoter activity correlates with the availability of electron acceptors at PSI. The photosynthetic redox-regulation can be simulated by oxidant and antioxidant treatments. Inhibitor studies with PD98059 and staurosporine showed that a mitogen-activated protein kinase kinase transmits the oxidative response, while the antioxidant signal is transmitted by a serine/threonine kinase. Analysis of 2CPA promoter regulation in the abscisic acid (ABA)-biosynthetic mutants aba2 and aba3 and the ABA-insensitive mutants abi1 and abi2 support a regulatory circuitry in which the redox signal cross-talks with the ABA-signaling cascade downstream of ABI1 and ABI2.[1]
