Abstract: Agricultural productivity worldwide is subject to increasing environmental constraints, particularly to drought and salinity due to their high magnitude of impact and wide distribution. Traditional breeding programs trying to improve abiotic stress tolerance have had some success, but are limited by the multigenic nature of the trait. Tolerant plants such as Craterostigma plantagenium, Mesembryanthemum crystallinum, Thellungiella halophila and other hardy plants could be valuable tools to dissect the extreme tolerance nature. In the last decade, Arabidopsis thaliana, a genetic model plant, has been extensively used for unravelling the molecular basis of stress tolerance. Arabidopsis also proved to be extremely important for assessing functions for individual stress-associated genes due to the availability of knock-out mutants and its amenability for genetic transformation. In this review, the responses of plants to salt and water stress are described, the regulatory circuits which allow plants to cope wit...

Polyamine metabolic canalization in response to drought stress in Arabidopsis and the resurrection plant Craterostigma plantagineum
Rubén Alcázar,Marta Bitrián,Dorothea Bartels,Csaba Koncz,Teresa Altabella,Antonio F. Tiburcio +5 more
TL;DR: The results suggest the participation of the polyamine back-conversion pathway during the drought stress response rather than the terminal catabolism of spermine, which confers an effective polyamine recycling-loop during drought acclimation.

MADS-box genes are key components of genetic regulatory networks involved in abiotic stress and plastic developmental responses in plants
Natalia Castelán-Muñoz,Joel Herrera,Wendy Cajero-Sanchez,Maite Arrizubieta,Carlos Trejo,Berenice García-Ponce,María de la Paz Sánchez,Elena R. Alvarez-Buylla,Adriana Garay-Arroyo +8 more
TL;DR: It is suggested that MADS-box genes are key components of gene regulatory networks involved in plant responses to stress and plant developmental plasticity in response to seasonal changes in environmental conditions.

Comparative Proteomics of Thellungiella halophila Leaves from Plants Subjected to Salinity Reveals the Importance of Chloroplastic Starch and Soluble Sugars in Halophyte Salt Tolerance
Xuchu Wang,Lili Chang,Lili Chang,Bai-Chen Wang,Daniel I. C. Wang,Pinghua Li,Pinghua Li,Limin Wang,Limin Wang,Xiaoping Yi,Qixing Huang,Ming Peng,Anping Guo,Anping Guo +13 more
TL;DR: A schematic representation of the systematic salt-tolerance phenotype in Thellungiella is proposed and it is suggested that the increased accumulation of starch, soluble sugars, and proline, as well as subcellular compartmentalization of sodium, might collectively denote important mechanisms for halophyte salt tolerance.

Calcineurin B-Like Protein-Interacting Protein Kinase CIPK21 Regulates Osmotic and Salt Stress Responses in Arabidopsis
Girdhar K. Pandey,Poonam Kanwar,Amarjeet Singh,Leonie Steinhorst,Amita Pandey,Akhilesh K. Yadav,Indu Tokas,Sibaji K. Sanyal,Beom-Gi Kim,Sung Chul Lee,Yong-Hwa Cheong,Joerg Kudla,Sheng Luan +12 more
TL;DR: Findings suggest that CIPK21 mediates responses to salt stress condition in Arabidopsis, at least in part, by regulating ion and water homeostasis across the vacuolar membranes.

Oxidative stress, antioxidants and stress tolerance
TL;DR: Key steps of the signal transduction pathway that senses ROIs in plants have been identified and raise several intriguing questions about the relationships between ROI signaling, ROI stress and the production and scavenging ofROIs in the different cellular compartments.

Comparative physiology of salt and water stress
TL;DR: It is important to avoid treatments that induce cell plasmolysis, and to design experiments that distinguish between tolerance of salt and tolerance of water stress, to understand the processes that give rise toolerance of salt, as distinct from tolerance of osmotic stress.

Salt and drought stress signal transduction in plants
TL;DR: Salt and drought stress signal transduction consists of ionic and osmotic homeostasis signaling pathways, detoxification (i.e., damage control and repair) response pathways, and pathways for growth regulation.
