Gametophytic Selection for Thermotolerance in Phalaenopsis
… indicates that gametophytic selection for thermotolerance in Phalaenopsis can be successfully used as a plant breeding tool. Additional replication is required to confirm the greater germinability of seed derived from pollination occurring over a greater range of temperatures.

Studies on the genetic basis for thermotolerance in Arabidopsis thaliana
… improved drought tolerance and also improved thermotolerance as low water availability reduces transpiration resulting in increased leaf temperatures. Identification of traits and genes involved in drought tolerance has been one of the major areas of plant research over the last decade, but …

Are thermotolerance and heat acclimation related through the heat shock response?
Thermotolerance (cellular adaptations that allow survival after an acute, severe heat exposure) and heat acclimation (systemic adaptations that improve heat dissipation following chronic heat exposure) have traditionally been considered separate phenomena. However, recent studies in animals suggest …

Study of Thermotolerance Mechanism in Gossypium Hirsutum Through Identification of Heat Stress Genes
<p>ABSTRACT</p> <p>Heat stress causes major losses to cotton seed and lint yield. Introduction of heat stress tolerance to Arkansas cotton varieties is highly desirable. However, very little is known about the molecular basis of heat stress tolerance in cotton. The present study attempted to …

Plasticity of the heat shock response and development of thermotolerance during embryonic development of Lake Whitefish (Coregonus clupeaformis)
Thermal discharge produced by industrial facilities has the potential to impact development of fish by increasing background temperature of the surrounding area. The overall objectives of this study were to: 1) Examine the interplay between how temperature and frequency of heat shock and post-heat …

Cellular signalling pathways involved in thermoprotection of neural ciruit function in the locust.
… It is unclear how HS preconditioning confers CNS thermotolerance. I used the migratory locust (Locusta migratoria), an animal that inhabits environments that can have large fluctuations in ambient temperature daily, to examine how neuronal circuits cope with temperatures stress. Using the …

The Heat Shock Proteins of Maize: Their Induction, Cellular Location, and Potential Function
… and their relationship to the establishment of thermotolerance.

Cloning of novel low and high molecular weight heat shock genes in wheat
… once significance of a HSP gene in plant thermotolerance is confirmed, beneficial cloned genes from thermotolerant varieties could be used to improve other wheat germplasm.

Physiological response to three environmental stressors predicts fitness and genome quality but not base substitution rate in caenorhabditis elegans
… at reducing nematode survival. We found that thermotolerance was higher in the HK104 strain of Caenorhabditis briggsae than the N2 strain C. elegans. Within the N2 strain, thermotolerance correlated with fitness. In experiments 1 and 2, exposure to high free radicals and high salt reduced …

The heat-shock response in <i>Serpula s</i>pecies at the cellular and molecular level
… response with respect primarily to induced thermotolerance and the production of hsps. The approach taken to establish the above was by systematic analysis of the different pathways involved in this response. Firstly, overall heat induced changes in protein and mRNA synthesis were analysed, …

Investigating photosynthetic mechanisms in model and non-model species
… showed that this gene is important in maize thermotolerance. The variability in response between the two genetic backgrounds used in this chapter also suggests variation in heat tolerance that could be utilized to study the interaction of rca3 with other genes and identify additional genes …

Characterization and Genetic Analysis of The Morphological Mutant <em>Crisp-5</em> of <em>Neurospora crassa</em>
… <p>Conidia of <em>cr-5</em> were tested for thermotolerance at 60<sup>o</sup>C heat shock temperature. The mutant <em>cr-5</em> exhibited thermotolerance. Therefore, when performing crosses with new mutants, it would be advisable to test the heat shock effect to avoid skewed results when …

Effect of neonatal heat stress on growth, mortality and blood characteristics of juvenile broilers exposed to high ambient temperature
… late heat exposure These results indicate that thermotolerance can be induced by exposing broiler chicks to 35.0 to 37.8 C for 24 hr at 5 days of age with no adverse effects on performance. Although the mechanism by which Early, neonatal, heat exposure induces thermotolerance is unknown, it is …

Deciphering Functional Significance of Substrate-Binding Domain of Ssa1 on Heat-Shock Response and Prion Propagation
… polar or nonpolar (tyrosine and phenylalanine), thermotolerance and [PSI+] can be maintained. However, there is a limit to side-chain size as too large, such as tryptophan, Ssa1 will lose intrinsic function and fail to support cell viability. By contrast, residue 483 prefer to smaller size amino …

Pathogen-Specific Adaptations to Conserved Signaling Pathways in Cryptococcus neoformans
… and Ras family GTPases are central regulators of thermotolerance in C. neoformans. Many GTPases require prenylation to associate with cellular membranes and function properly. Using molecular genetic techniques, microscopy, and infection models, I demonstrated that the prenyltransferase, …

Investigating the physiological and metabolomic effects of Ecklonia maxima-derived biostimulant foliar application in ameliorating the effects of heat shock in tomato plants
… improved cell membrane integrity and enhanced thermotolerance of E. maxima treated plants in response to heat shock stress. There was also a reduction in lipid peroxidation and proline content in heat shocked plants treated prior with E. maxima-derived biostimulant, indicating enhanced ROS …

Mechanisms Regulating the Response of Arabidopsis thaliana to Heat Stress
… demonstrated that MBF1c is a key regulator of thermotolerance in Arabidopsis thaliana. MBF1c protein accumulates rapidly and is localized to nuclei during heat stress. MBF1c functions upstream to SA, trehalose, ethylene, and pathogenesis-related protein 1 (PR-1) during heat stress. In contrast, …
