Cold temperature is an important abiotic stress which negatively affects morphological development and seed production in rice (Oryza sativa L.). At the seedling stage, cold stress causes poor germination, seedling injury and poor stand establishment; and at the reproductive stage cold decreases seed yield. The Rice Diversity Panel 1 (RDP1) is a global collection of over 400 O. sativa accession...

Abiotic stress, including salinity, drought and cold, severely affect diverse aspects of plant development and production. Rice is an important crop that does not acclimate to cold; therefore, it is relatively sensitive to low temperature stress. Dehydration-responsive element-binding protein 1s (DREB1s)/C-repeat binding factors (CBFs) are well known for their function in cold tolerance, but th...

Ethylene (ET) is a gaseous plant hormone that plays essential roles in biotic and abiotic stress responses in plants. However, the role of ET in cold tolerance varies in different species. This study revealed that low temperature promotes the release of ET in grapevine. The treatment of exogenous 1-aminocyclopropane-1-carboxylate increased the cold tolerance of grapevine. By contrast, the appli...

We examined the relationship between acute stress and prefrontal-cortex (PFC) based working memory (WM) systems using behavioral (Experiment 1) and functional magnetic resonance imaging (fMRI; Experiment 2) paradigms. Subjects performed a delayed-response item-recognition task, with alternating blocks of high and low WM demand trials. During scanning, participants performed this task under thre...

This is the first study to show a quantitative thermographic difference between patients with Raynaud's syndrome and normal controls after cold stress testing. An improved thermographic response to cold stress testing after treatment of Raynaud's syndrome with PGE1 has also been shown for the first time. Discriminant analysis of the change in temperature of a finger after cold stress, and the m...

Recent research indicates gender differences in the impact of stress on decision behavior, but little is known about the brain mechanisms involved in these gender-specific stress effects. The current study used functional magnetic resonance imaging (fMRI) to determine whether induced stress resulted in gender-specific patterns of brain activation during a decision task involving monetary reward...

Transcriptome analysis of sugarcane hybrid CP72-1210 (cold susceptible) and Saccharum spontaneum TUS05-05 (cold tolerant) using Sugarcane Assembled Sequences (SAS) from SUCEST-FUN Database showed that a total of 35,340 and 34,698 SAS genes, respectively, were expressed before and after chilling stress. The analysis revealed that more than 600 genes are differentially expressed in each genotype ...

EFFECTOF COLD STRESS ON GLYCOGEN AND CHOLINESTERASE CONTENTS OF RAT MYOCARDIUM AND ITS MODIFICATION BY PHYSOSTIGMINE * By V.N. SHARMA AND N.K. KHANNA *'" Department of Pharmacology and Experimental Therapeutics, S.M.S. Medical College, Jaipur. A marked depletion of myocardial glycogen occurs under different stressful situations 4,5,11, 13, 14). There is a rise in acetylcholine content of rat my...

Chlamydomonas reinhardtii is one of the most important model organisms nowadays phylogenetically situated between higher plants and animals (Merchant et al. 2007). Stress adaptation of this unicellular model algae is in the focus because of its relevance to biomass and biofuel production. Here, we have studied cold stress adaptation of C. reinhardtii hitherto not described for this algae wherea...
