Abstract

Like all organisms, plants have to be able to respond to a wide range of environmental factors. Accordingly, single plant cells require perception and responsiveness mechanisms for a variety of inner and outer signals. Nitric oxide is one of the signal molecules actively used by plants during growth, development and survival of stressful conditions. Recent experimental data has revealed that NO is involved in reproductive processes, control of certain life cycle periods and regulation of physiological responses such as stomatal closure. Although signalization pathways and mechanisms of nitric oxide synthesis are well studied in animal systems, there still remain many fundamental questions regarding plants that need to be resolved. NO is a relatively reactive molecule, and thus not always easy to study. Additionally, its biological activity needs to be observed in regard to interaction with other volatile compounds such as reactive oxygen species (ROS), which have the ability to strongly modulate accumulation and function of affected substances. A great deal of interest remains regarding further explorations of NO role in the domain of plant physiology since only the missing answers can help explain the complex network of reactions leading to adverse or beneficial effects in plants.
