Abstract

Nitric oxide (NO) has received much attention in the recent two decades, equally from human, animal and plant biologists. It was found to play a crucial role in human and animal physiology, immunological reactions and signal transduction. Its ubiquity and versatile properties caught the attention of plant physiologists and biochemists. This work presents an extensive review on the NO presence and action in plants. Various modes of NO synthesis are discussed and the most novel approaches to the elucidation of plant nitric oxide synthase (NOS) structure are presented. This review focuses on the physiological role of NO in regulation of plant growth and development, as well as in the process of gene expression. Special attention is given to the action of NO during abiotic stress and the antioxidant properties of the molecule.
