Sumario:Phytohormones participate in many aspects of the plant life cycle, including responses to biotic and abiotic stresses. They play a key role in plant responses to the environment with direct bearing on a plant?s fitness for adaptation and reproduction. In recent years, there have been major advances in our understanding of the role of phytohormones in halophytic plants. The variability in maximal salinity level that halophytes can tolerate makes it difficult to characterize the specific traits responsible for salt tolerance. However, the most evident effect of salinity is growth disturbance, and growth is directly governed by phytohormones. Phytohormones such as abscisic acid, salicylic acid ethylene and jasmonates are traditionally related to stress responses, while the involvement of cytokinins, gibberellins and auxins has started to be analyzed. Polyamines, although they can?t be considered phytohormones because of the high concentrations required for cell responses, have been proposed as a new category of plant growth regulators involved in several plant processes and stress responses. This review integrates the advances in the knowledge about phytohormones in halophytes and their participation in salt tolerance.
