DcHsp17.7, a small heat shock protein in carrot, is tissue-specifically expressed under salt stress and confers tolerance to salinity.
Na-Hyun Song,Yeh-Jin Ahn +1 more
TL;DR: The expression and function of DcHsp17.7, a small heat shock protein in carrot, were examined under salt stress, which is an exacerbating environmental condition due to water shortage and irrigation, and showed tissue-specific oligomer formation.

Beyond osmolytes and transcription factors: drought tolerance in plants via protective proteins and aquaporins
TL;DR: The molecular and functional characterization of protective proteins and aquaporins has revealed the significance of their regulation in response to abiotic stresses, and new findings regarding the action mechanisms of these proteins are highlighted.

Do Halophytes Really Require Salts for Their Growth and Development? An Experimental Approach
TL;DR: Results indicate that salts are not compulsorily required for development of halophytic species, and suggest that limitation of water and nutrients, rather than soil salinity per se, are the most important restrictive factors for plant growth in saline habitats.

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.

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.
Journal ArticleDOI
Role of plant heat-shock proteins and molecular chaperones in the abiotic stress response
TL;DR: The significance of Hsps and chaperones in abiotic stress responses in plants is summarized, and the co-operation among their different classes and their interactions with other stress-induced components are discussed.
Journal ArticleDOI
Improving crop salt tolerance
TL;DR: Evaluation of claims in the literature that the transfer of a single or a few genes can increase the tolerance of plants to saline conditions reveals that, of the 68 papers produced between 1993 and early 2003, only 19 report quantitative estimates of plant growth.

Regulatory network of gene expression in the drought and cold stress responses.
TL;DR: This work has shown that several genes with various functions are induced by drought and cold stresses, and that various transcription factors are involved in the regulation of stress-inducible genes.
