Abstract Hydrogen peroxide (H2O2) is an important signal molecule involved in plant
development and environmental responses. Changes in H2O2 availability can result from …

Photorespiratory metabolism allows plants to thrive in a high-oxygen containing
environment. This metabolic pathway recycles phosphoglycolate, a toxic compound, back to …

Photorespiration is initiated by the oxygenase activity of ribulose-1, 5-bisphosphate-
carboxylase/oxygenase (RUBISCO), the same enzyme that is also responsible for CO 2 …

Abstract The 55 Arabidopsis glutathione transferases (GSTs) are, with one microsomal
exception, a monophyletic group of soluble enzymes that can be divided into phi, tau, theta …

Peroxisomes are organelles bounded by a single membrane that can be found in all major
groups of eukaryotes. A single evolutionary origin of this cellular compartment is supported …

Recent advances in the proteomic field have allowed high throughput experiments to be
conducted on chloroplast samples and the data are available in several databases such as …

The analysis of plant proteomes has drastically expanded in the last few years. Mass
spectrometry technology, stains, software and progress in bioinformatics have made …

Since the proposal of the signal hypothesis on protein subcellular sorting, a number of
computational analyses have been performed in this field. A typical example is the …

We recently established a proteome methodology for Arabidopsis leaf peroxisomes and
identified more than 90 putative novel proteins of the organelle. These proteins included …

Peroxisomes are a family of organelles which have many unusual features. They can arise
de novo from the endoplasmic reticulum by a still poorly characterized process, yet possess …
