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.
Journal ArticleDOI
Roles of glycine betaine and proline in improving plant abiotic stress resistance
Muhammad Ashraf,Majid R. Foolad +1 more
TL;DR: In this review article, numerous examples of successful application of these compounds to improve plant stress tolerance are presented and a better understanding of the mechanisms of action of exogenously applied GB and proline is expected to aid their effective utilization in crop production in stress environments.
Journal ArticleDOI
Plant responses to drought, salinity and extreme temperatures: towards genetic engineering for stress tolerance
TL;DR: The present review summarizes the recent advances in elucidating stress-response mechanisms and their biotechnological applications and examines the following aspects: regulatory controls, metabolite engineering, ion transport, antioxidants and detoxification, late embryogenesis abundant (LEA) and heat-shock proteins.

Na+ Tolerance and Na+ Transport in Higher Plants
Mark Tester,Romola Davenport +1 more
TL;DR: This work suggests that equally important in a wide range of conditions are processes involving the management of Na(+) movements within the plant, and requires more knowledge of cell-specific transport processes and the consequences of manipulation of transporters and signalling elements in specific cell types.

TL;DR: This new handbook has a better balance between whole-plant traits, leaf traits, root and stem traits and regenerative traits, and puts particular emphasis on traits important for predicting species’ effects on key ecosystem properties.

Journal ArticleDOI
Two transcription factors, DREB1 and DREB2, with an EREBP/AP2 DNA binding domain separate two cellular signal transduction pathways in drought- and low-temperature-responsive gene expression, respectively, in Arabidopsis.
Qiang Liu,Mie Kasuga,Yoh Sakuma,Hiroshi Abe,Setsuko Miura,Kazuko Yamaguchi-Shinozaki,Kazuo Shinozaki +6 more
TL;DR: Overexpression of the DREB1A cDNA in transgenic Arabidopsis plants not only induced strong expression of the target genes under unstressed conditions but also caused dwarfed phenotypes in the transgenic plants, and revealed freezing and dehydration tolerance.
Journal ArticleDOI
Improving plant drought, salt, and freezing tolerance by gene transfer of a single stress-inducible transcription factor
TL;DR: This article showed that over-expression of the cDNA encoding DREB1A in transgenic plants activated the expression of many of these stress tolerance genes under normal growing conditions and resulted in improved tolerance to drought, salt loading, and freezing.
Journal ArticleDOI
The mechanism of salt tolerance in halophytes
TL;DR: The objective was to establish an experimental procedure and show direct AFM measurements that unequivocally can be assigned as a mode of action for the conversion of NalK to Na6(SO4)(SO3) during the cycling process.
Journal ArticleDOI
Salt Tolerance Conferred by Overexpression of a Vacuolar Na+/H+ Antiport in Arabidopsis
TL;DR: Overexpression of a vacuolar Na+/H+ antiport fromArabidopsis thaliana in Arabidopsis plants promotes sustained growth and development in soil watered with up to 200 millimolar sodium chloride, demonstrating the feasibility of engineering salt tolerance in plants.

Arabidopsis thaliana CBF1 encodes an AP2 domain-containing transcriptional activator that binds to the C-repeat/DRE, a cis-acting DNA regulatory element that stimulates transcription in response to low temperature and water deficit
TL;DR: It is concluded that CBF1 can function as a transcriptional activator that binds to the C-repeat/DRE DNA regulatory element and, thus, is likely to have a role in cold- and dehydration-regulated gene expression in Arabidopsis.
