Arabidopsis thaliana--a model organism to study plant peroxisomes

Abstract

In higher plants, peroxisomes have been believed to play a pivotal role in three metabolic pathways, which are lipid breakdown, photorespiration and H2O2-detoxificaton. Recently, significant progress in the study of plant peroxisomes was established by forward-/reverse-genetics and post-genomic approaches using Arabidopsis thaliana, the first higher plant to have its entire genome sequenced. These studies illustrated that plant peroxisomes have more diverse functions than we previously thought. Research using Arabidopsis thaliana is improving our understanding of the function of plant peroxisomes.
