Abstract
Peroxisomes in higher plant cells are known to differentiate in function depending on the cell type and environmental condition. This remarkable feature of plant peroxisomes is not found in other organisms. In the last decade, significant progress has been made in the study of plant peroxisomal function and its regulation. These studies illustrated that plant peroxisomes have more diverse functions than we previously though, and allowed to identify many genes involving peroxisomal protein targeting and peroxisome biogenesis. We describe recent achievement on the study of peroxisomal function and its regulation in plant cells.
