Beta-oxidation in fatty acid degradation and beyond.
The degradation of fatty acids in plants occurs primarily in the peroxisomes through the beta-oxidation cycle. Enzymes that are involved in various aspects of beta-oxidation have been identified recently and shown to act biochemically on a diversity of fatty acids and derivatives. Analysis of several mutants has revealed essential roles for beta-oxidation in the breakdown of reserve triacylglycerols, seed development, seed germination and post-germinative growth before the establishment of photosynthesis. Beta-oxidation has also a considerable importance during the vegetative and reproductive growth phases, and plays a role in plant responses to stress, particularly in the synthesis of jasmonic acid.
