The mechanisms of sensing and signalling of heat and oxidative stresses are not well understood. The central question of this paper is whether in plant cells oxidative stress, in particular H2O2, is required for heat stress- and heat shock factor (HSF)-dependent expression of genes. Heat stress increases intracellular accumulation of H2O2 in Arabidopsis cell culture. The accumulation was greatly diminished...
Oxygen-free radicals are thought to play an essential role in senescence. Therefore, the expression patterns of the small gene family encoding the H2O2 scavenging enzymes ascorbate peroxidase (APX; EC 1.11.1.11) were analyzed during senescence of Arabidopsis thaliana (L.) Heinh. Applying real-time RT-PCR, the mRNA levels were quantified for three cytosolic (APX1, APX2, APX6), two chloroplastic types...
