In recent years, forward and reverse genetic studies along with bio- chemical and cell biological analyses in Arabidopsis have enabled researchers to identify many peroxisome proteins and elucidate their functions. This review focuses on the advances in our understanding of peroxisome biogenesis and metabolism, and further explores the contribution of large-scale analysis, such as in silico predictions and proteomics, in augmenting our knowledge of peroxisome function in Arabidopsis. 1. INTRODUCTION: A HISTORICAL OVERVIEW Following their ± rst discovery in mouse kidney through micros- copy, peroxisomes underwent extensive studies by Christian de Duve and Pierre Baudhuin. These researchers used rat liver cells to provide biochemical evidence for the presence of hydrogen peroxide (H 2 O 2 )-producing and -degrading activities in these subcellular structures, which led to their being named peroxisomes (De Duve and Baudhuin, 1966). Peroxisomes are small eukaryotic organelles surrounded by a single membrane and specialized in oxidative metabolic reactions. They are devoid of nucleic acids and ribosomes and import their complement of proteins post-translationally from the cytosol. The physiological signi± cance of peroxisomes is underscored by the occurrence
