Abstract
Peroxisomes are single membrane-bound organelles that are ubiquitously found in eukaryotic cells and have pivotal roles in β-oxidation of fatty acids and degeneration of hydrogen peroxide. Additionally, peroxisomes in higher plants have specialized functions, such as biosynthesis of phytohormones and photorespiration. Since unlike mitochondria and chloroplasts, peroxisomes does not have own genome, the enzymes participated in peroxisomal functions are encoded in nuclear genome and transported into peroxisomes after protein synthesis in the cytosol. The functions of peroxisomes are plastically controlled under environmental changes. However, precise machineries of differentiation of peroxisomes have not been clarified. To identify the factors regulating peroxisome biogenesis, we have screened the aberrant peroxisome morphology (apm) mutants, in which peroxisomes display abnormal phenotypes, elongated or enlarged peroxisomes. Some mutants show a defect in peroxisomal protein transport. In this presentation, we will report the recent work on the machinery of peroxisomal protein transport in higher plants.
