Journal ArticleDOI
Transcriptional profiling of Medicago truncatula under salt stress identified a novel CBF transcription factor MtCBF4 that plays an important role in abiotic stress responses.
TL;DR: Comprehensive transcriptomic analysis revealed complex mechanisms exist in plants in response to salt stress and identified a novel transcription factor gene, MtCBF4, which might be a good candidate gene for genetic improvement to produce stress-tolerant plants.
Journal ArticleDOI
Can interaction between silicon and plant growth promoting rhizobacteria benefit in alleviating abiotic and biotic stresses in crop plants
TL;DR: In this article, the authors compare and contrast the mechanisms, as far as they are known, through which Si and rhizobacteria can alleviate abiotic and biotic stresses in plants.

Brassinosteroid (24-epibrassinolide) enhances growth and alleviates the deleterious effects induced by salt stress in pea (Pisum sativum L.)
Muhammad Shahid,Muhammad Aslam Pervez,Rashad Mukhtar Balal,Neil S. Mattson,A. Rashid,Rashid Ahmad,Chaudhary Muhammad Ayyub,Tahira Abbas +7 more
TL;DR: Plants subjected to saline stress exhibited a reduction in all the morpho-physiological and enzymatic attributes but proline contents and enzyme activities of antioxidants were enhanced in response to NaCl stress, however, deleterious effects induced by salinity were reduced if seeds were treated with EBL before or after NaCl imbibitions.
Journal ArticleDOI
Osmotin: a plant sentinel and a possible agonist of mammalian adiponectin.
TL;DR: The vital role of osmotin is examined as a potential targeted therapeutic drug for humans and as a stress responsive antifungal protein that protects the cells from osmotic stress and invading pathogens as well, by structural or metabolic alterations.

SiLEA14, a novel atypical LEA protein, confers abiotic stress resistance in foxtail millet.
Meizhen Wang,Meizhen Wang,Li Ping,Cong Li,Yanlin Pan,Xiyuan Jiang,Dengyun Zhu,Qian Zhao,Jingjuan Yu +8 more
TL;DR: It is indicated that SiLEA14 is a novel atypical LEA protein and plays important roles in resistance to abiotic stresses in plants, which may improve abiotic stress resistance in agricultural crops.

Journal ArticleDOI
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.
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.
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.
Journal ArticleDOI
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.
