Plant tolerance to high temperature in a changing environment: scientific fundamentals and production of heat stress-tolerant crops
Craita E. Bita,Tom Gerats +1 more
TL;DR: There is a differential effect of climate change both in terms of geographic location and the crops that will likely show the most extreme reductions in yield as a result of expected extreme fluctuations in temperature and global warming in general.
Journal ArticleDOI
Effect of salinity stress on plants and its tolerance strategies: a review.
TL;DR: The understanding of salinity impact on various aspects of plant metabolism and its tolerance strategies in plants is reviewed and it appears to be a major constraint to plant and crop productivity.
Journal ArticleDOI
Temperature stress and plant sexual reproduction: uncovering the weakest links
TL;DR: Studies of temperature stress on several crop plants suggest that pollen development and fertilization may often be the most sensitive reproductive stage, which offers the potential to identify genetic traits that could be manipulated to improve temperature tolerance in selected crop species being cultivated in marginal climates.
Journal ArticleDOI
Phytohormones and their metabolic engineering for abiotic stress tolerance in crop plants
TL;DR: This review summarizes and critically assess the roles that phytohormones play in plant growth and development and abiotic stress tolerance, besides their engineering for conferring abiotics stress tolerance in transgenic crops, and describes the recent progress and future prospects.

Chilling and Drought Stresses in Crop Plants: Implications, Cross Talk, and Potential Management Opportunities
Hafiz Athar Hussain,Saddam Hussain,Abdul Khaliq,Umair Ashraf,Shakeel Ahmad Anjum,Shengnan Men,Longchang Wang +6 more
TL;DR: There is still a big room for improvement in combination of drought and chilling tolerance and future researches particularly using biotechnological and molecular approaches should be carried out to develop genetically engineered plants with enhanced tolerance against these stress factors.

Responses of plants to environmental stresses
TL;DR: In this article, the authors investigated the responses of plants to environmental stresses and found that plants respond to environmental stress in response to various types of stressors, such as drought and flooding.

PLANT COLD ACCLIMATION: Freezing Tolerance Genes and Regulatory Mechanisms
TL;DR: This review of recent advances in determining the nature and function of genes with roles in freezing tolerance and the mechanisms involved in low temperature gene regulation and signal transduction concludes that cold acclimation includes the expression of certain cold-induced genes that function to stabilize membranes against freeze-induced injury.

Monitoring the expression profiles of 7000 Arabidopsis genes under drought, cold and high-salinity stresses using a full-length cDNA microarray.
Motoaki Seki,Mari Narusaka,Junko Ishida,Tokihiko Nanjo,Miki Fujita,Youko Oono,Asako Kamiya,Maiko Nakajima,Akiko Enju,Tetsuya Sakurai,Masakazu Satou,Kenji Akiyama,Teruaki Taji,Kazuko Yamaguchi-Shinozaki,Piero Carninci,Jun Kawai,Yoshihide Hayashizaki,Kazuo Shinozaki +17 more
TL;DR: A full-length cDNA microarray containing approximately 7000 independent, full- length cDNA groups is prepared to analyse the expression profiles of genes under drought, cold (low temperature) and high-salinity stress conditions over time, suggesting that various transcriptional regulatory mechanisms function in the drought,cold or high- salinity stress signal transduction pathways.

Sugar Sensing and Signaling in Plants: Conserved and Novel Mechanisms
TL;DR: In this article, the experimental amenability of yeast as a unicellular model system has enabled the discovery of multiple sugar sensors and signaling pathways, and a central role for hexokinase (HXK) as conserved glucose sensor.
