S-Nitrosoglutathione (GSNO) is a bioactive, stable, and mobile reservoir of nitric oxide (NO), and an important player in defence responses to herbivory and pathogen attack in plants. It has been demonstrated previously that GSNO reductase (GSNOR) is the main enzyme responsible for the in vivo control of intracellular levels of GSNO. In this study, the role(More)
Protein kinase CK2 is a ubiquitous Ser/Thr/Tyr kinase essential for cell viability in eukaryotes. It comprises alpha catalytic and beta regulatory subunits, which combine to form the classical tetrameric structure, alpha2beta2. Although CK2 is a component of the network that controls the eukaryotic cell cycle, very little is known about the expression(More)
The glutathione-dependent formaldehyde dehydrogenase (FALDH) is the main enzyme of the formaldehyde detoxi-fication system in eukaryotes. In Arabidopsis FALDH is coded by a single gene, which is constitutively expressed [1]. By immunolocalization experiments on Arabidopsis root and leaf sections, we demonstrate that the pattern of expression of the enzyme(More)
