Role of proline under changing environments: a review.
TL;DR: Review of the literature indicates that a stressful environment results in an overproduction of proline in plants which in turn imparts stress tolerance by maintaining cell turgor or osmotic balance; stabilizing membranes thereby preventing electrolyte leakage; and bringing concentrations of reactive oxygen species within normal ranges, thus preventing oxidative burst in plants.

Drought, salt, and temperature stress-induced metabolic rearrangements and regulatory networks
Julia Krasensky,Claudia Jonak +1 more
TL;DR: Information about metabolic regulation in response to drought, extreme temperature, and salinity stress is summarized and the signalling events involved in mediating stress-induced metabolic changes are presented.

Plant salt-tolerance mechanisms
Ulrich Deinlein,Aaron B. Stephan,Tomoaki Horie,Wei Luo,Wei Luo,Guohua Xu,Julian I. Schroeder +6 more
TL;DR: The understanding of the core salt-tolerance mechanisms in plants is reviewed and key Na+ transport and detoxification pathways and the impact of epigenetic chromatin modifications on salinity tolerance are reviewed.

Morphological, physiological and biochemical responses of plants to drought stress
TL;DR: The ability and strategies of higher plants to respond and adapt to drought stress are focused on, including the critical roles of osmolyte accumulation under drought stress conditions.
Plant Responses to Salt Stress: Adaptive Mechanisms
José Ramón Acosta-Motos,María Fernanda Ortuño,Agustina Bernal-Vicente,Pedro Diaz-Vivancos,María Jesús Sánchez-Blanco,José Antonio Hernández +5 more
TL;DR: This review deals with the adaptive mechanisms that plants can implement to cope with the challenge of salt stress, including morphological, physiological and biochemical changes, and some of the mechanisms thought to protect the photosynthetic machinery.

Photosynthesis under drought and salt stress: regulation mechanisms from whole plant to cell
TL;DR: It is becoming apparent that plants perceive and respond to drought and salt stresses by quickly altering gene expression in parallel with physiological and biochemical alterations; this occurs even under mild to moderate stress conditions.

Hydroxyl radical scavenging activity of compatible solutes
TL;DR: Of the compatible solutes tested, sorbitol, mannitol, myo-inositol and proline were effective hydroxyl radical scavengers and Glycinebetaine was ineffective.

Proline accumulation in plants: a review.
TL;DR: Proline (Pro) accumulation is a common physiological response in many plants in response to a wide range of biotic and abiotic stresses as discussed by the authors, and controversy has surrounded the possible role(s) of proline accumulation.

Metabolic implications of stress-induced proline accumulation in plants
P.D. Hare,W.A. Cress +1 more
TL;DR: A mechanism is proposed whereby the interconversions of proline and P5C in different cell types and the associated transfer of redox potential between tissues may constitute a form of metabolic signalling within higher plants.
