Plant peroxisomes: structure, localization, function.
Pivoňka, Jaroslav ; Schwarzerová, Kateřina (advisor) ; Kutík, Jaromír (referee)
Plant cell is a complex and complicated environment where countless biochemical processes and metabolic pathways take place independently of each other. Some of them could pose a threat to a plant cell or be a cause of organism lethality altogether, mainly because of their antagonistic character or by their toxicity. To eliminate this danger and ensure the most effective course of these reactions, a separation into properly separated and safe compartments is being applied. This phenomenon is called cellular compartmentalization and these sections are called organelles. Peroxisomes are one of them. They are highly dynamic and metabolically diverse vesicles of spherical nature, formed by a single-layered membrane. They contain crucial enzymes that operate in processes such as reactive oxygen species (ROS) metabolism, photorespiration, storage oils breakdown followed by β-oxidation of fatty acids, glyoxylate cycle, phytohormones biosynthesis, and more and more of other metabolic pathways. By that, they stand as an essential imaginary crossroad connecting these critical processes in plant development and physiological responses to abiotic and biotic stresses. This work is focused on reviewing these peroxisomal functions in plant cells, as well as the peroxisomal structure, its proteome and biogenesis....
