TLDR
‘Stress’ in plants can be defined as any external factor that negatively influences plant growth, productivity, reproductive capacity or survival.Abstract:
‘Stress’ in plants can be defined as any external factor that negatively influences plant growth, productivity, reproductive capacity or survival. This includes a wide range of factors which can be broadly divided into two main categories: abiotic or environmental stress factors, and biotic or biological stress factors.

ROS homeostasis in halophytes in the context of salinity stress tolerance
TL;DR: It is argued that truly salt-tolerant species possessing efficient mechanisms for Na(+) exclusion from the cytosol may not require a high level of antioxidant activity, as they simply do not allow excessive ROS production in the first instance.
INVITED REVIEW Learning from halophytes: physiological basis and strategies to improve abiotic stress tolerance in crops
TL;DR: This review argues that learning from halophytes may be a promising way of achieving salinity tolerance in non-halophytes and what specific genes need to be targeted to achieve this goal.

Transcript Analysis of Early Nodulation Events in Medicago truncatula
Dasharath P. Lohar,Natalya Sharopova,Gabriella Endre,Silvia Penuela,Deborah A. Samac,Christopher D. Town,Kevin A. T. Silverstein,Kathryn A. VandenBosch +7 more
TL;DR: Hundreds of genes of both known and unknown function were significantly regulated at these time points of the symbiosis between Medicago truncatula roots and Sinorhizobium meliloti, shedding light on the complexity of coordinated gene regulation.
Journal ArticleDOI
Polyamines control of cation transport across plant membranes: implications for ion homeostasis and abiotic stress signaling
TL;DR: The effects of polyamines and their catabolites on cation transport in plants are summarized and the implications for ion homeostasis, signaling, and plant adaptive responses to environment are discussed.

Autophagy contributes to regulation of the hypoxia response during submergence in Arabidopsis thaliana
Liang Chen,Bin Liao,Hua Qi,Li-Juan Xie,Li Huang,Wei-Juan Tan,Ning Zhai,Li-Bing Yuan,Ying Zhou,Lu-Jun Yu,Qin-Fang Chen,Wen-Sheng Shu,Shi Xiao +12 more
TL;DR: It is demonstrated that submergence-induced autophagy functions in the hypoxia response in Arabidopsis by modulating SA-mediated cellular homeostasis.

ASCORBATE AND GLUTATHIONE: Keeping Active Oxygen Under Control
Graham Noctor,Christine H. Foyer +1 more
TL;DR: A detailed account of current knowledge of the biosynthesis, compartmentation, and transport of these two important antioxidants, with emphasis on the unique insights and advances gained by molecular exploration are provided.
Journal ArticleDOI
The oxidative burst in plant disease resistance
TL;DR: Emerging data indicate that the oxidative burst reflects activation of a membrane-bound NADPH oxidase closely resembling that operating in activated neutrophils, which underlies the expression of disease-resistance mechanisms.

Abscisic acid signal transduction
Jeffrey Leung,Jérôme Giraudat +1 more
TL;DR: Substantial evidence points to the importance of reversible protein phosphorylation and modifications of cytosolic calcium levels and pH as intermediates in ABA signal transduction.

OXYGEN DEFICIENCY AND ROOT METABOLISM: Injury and Acclimation Under Hypoxia and Anoxia
TL;DR: This review examines how roots are injured by O2 deficiency and how metabolism changes during acclimation to low concentrations of O2, and indicates that selective sacrifice of cells may resemble programmed cell death and is distinct from cell death caused by anoxia.
Journal ArticleDOI
Role of Cold-Responsive Genes in Plant Freezing Tolerance
TL;DR: The ability of plants to survive freezing temperatures varies greatly, with plants from tropical regions that have virtually no capacity to survive even the slightest freeze and herbaceous plants from temperate regions generally survive freezing temperature ranges.
