    Intracellular H2O2 has emerged as a central player in signalling and stress acclimation, but how specificity is achieved remains elusive. Cytosolic peroxiredoxins play a decisive role as they sense H2O2 and transmit the oxidation signal through the formation of disulfide bridges, leading to stomatal closure that reduces pathogen entry.

    Regulation of organ growth involves multiple pathways that coordinate cell number and size in a process that is highly dependent on nutrient supply and energy levels. The simplicity of the Arabidopsis root tip provides a suitable model for the genetic dissection of plant organ growth regulation.
