Abstract

Peroxisomes are small multi-functional organelles essential for plant development and growth. Plant peroxisomes play various physiological roles, including phytohormone biosynthesis, lipid catabolism, reactive oxygen species metabolism and many others. Mutant analysis demonstrated key roles for peroxisomes in plant reproduction, seed development and germination and post-germinative seedling establishment; however, the underlying mechanisms remain to be fully elucidated. This review summarizes findings that reveal the importance and complexity of the role of peroxisomes in the pertinent processes. The β-oxidation pathway plays a central role, whereas other peroxisomal pathways are also involved. Understanding the biochemical and molecular mechanisms of these peroxisomal functions will be instrumental to the improvement of crop plants.

摘要

过氧化物酶体是小型多功能细胞器，对植物的发育和生长至关重要。植物过氧化物酶体发挥着各种生理作用，包括植物激素的生物合成、脂质分解代谢、活性氧代谢等。突变体分析表明，过氧化物酶体在植物繁殖、种子发育和萌发以及萌发后幼苗的建立中起着关键作用；然而，其潜在的机制仍有待充分阐明。本综述总结了一些发现，这些发现揭示了过氧化物酶体在相关过程中的重要性和复杂性。β-氧化途径起着核心作用，而其他过氧化物酶体途径也参与其中。了解这些过氧化物酶体功能的生化和分子机制对于改良作物植物将是非常重要的。
