Denitrification Under Salinity Stress in Biofilm Reactors
… etc. To improve the process’ performance under salinity inhibition, biofilm reactors could represent an elegant strategy, but a systematic analysis focusing on the reactor system under salinity stress is needed for their optimisation. Moreover, since the electron donors available for the process …

Investigating the molecular mechanism whereby auxin modulates Arabidopsis thaliana growth under salinity stress conditions
… global problem in irrigated agricultural land. Salinity imposes both an osmotic and ionic stress on plants, the latter of which is unique to salt stress. Previous work has indicated that the plant growth hormone auxin could play an important role in ionic stress tolerance: transcriptome …

Benzoic acid regulates the physio-biochemical responses of chia (Salvia hispanica L.) seedlings under salinity stress
… susceptible to various abiotic and biotic stresses. These stresses generate reactive oxygen species (ROS), which cause cellular damage through osmotic or oxidative stress, ultimately constraining agricultural productivity worldwide. To mitigate the challenges caused by these stresses, …

GENETIC PARAMETERS FOR HEAT AND SALINITY STRESS TOLERANCE IN NORTHERN GULF OF MEXICO EASTERN OYSTER, CRASSOSTREA VIRGINICA
… high temperatures, and chronic exposure to low salinity. In this study, the feasibility of improving tolerance to these two stresses by selection was evaluated in common garden experiments employing a pool of 160 families. Heat stress tolerance was evaluated in seed (3.5 months) and adults (14 …

Physiological response of two turfgrass species to increasing drought and salinity stress using a line source gradient
… Water use efficiency decreased with increasing salinity in tall fescue but not in bermudagrass. Tissue ion concentrations remained unchanged with increasing {dollar}\rm\Psi\sb{T}{dollar} in bermudagrass, while all ion concentrations in tall fescue, except K, increased with increasing …

Effects of salinity stress, ammonia exposure and feeding on excretory nitrogen metabolism in the marble goby, oxyeleotris marmorata
This study examined the effects of seawater acclimation, exposure to ammonia in freshwater or seawater or feeding on the marble goby, Oxyeleotris marmorata. O. marmorata exhibited hyperosmotic hyperionic regulation in freshwater, but undergo hypoosmotic hypoionic regulation during seawater …

Impact of growth stage, supplemental red LED, and salinity stress on the quality and aroma attributes of hydroponic fennel (Foeniculum vulgare Mill.)
… In particular, supplemental red light and salinity are known to modulate the production of aroma compounds in herbs, but the molecular mechanisms underlying these effects remain largely unexplored. Controlled environment agriculture (CEA) provides an ideal platform for studying plant …

Atvps34, the Arabidopsis Phosphotidylinositol 3-Kinase, Its Functions in ABA and Auxin Signaling Pathways and the Molecular Basis for Salinity Stress Tolerance in Extremophile Thellungiella Halophila
… revealed shared and divergent responses to salt stress in the two species. Sixty percent of regulated genes distinguished Thellungiella from Arabidopsis. Analysis of the differences showed that Arabidopsis took a global defense strategy that required bulk protein synthesis, while Thellungiella …

Amelioration of salinity toxicity in South African crop plants with special reference to maize
… gas exchange and growth responses to salinity stress (80 mM) together with the ameliorative roles of three ranges of calcium concentrations (2.5 to 12 mM, 1 to 8 mM and 0.5 to 5 mM) and one range of potassium concentrations (0.2 to 5 mM) were investigated in Zea mays L. var PNR 394. …

Upland Migration of Coastal Marshes as a Response to Sea Level Rise and Fire Management: Past, Present, and Predicted
… under threat due to natural and anthropogenic stressors, such as sea level rise (SLR). SLR can cause marshes to drown, converting them to open water. Marshes can respond to SLR through landward migration when suitable habitat is available. My research focuses on the landward migration pattern …

XvERD15, an early-responsive gene to stress from Xerophyte viscosa
… that are upregulated in the early response to stress are not well understood. ERD15 (early-responsive to dehydration) in Arabidopsis and its homologues in various other plants have been shown to be upregulated within I hr post-exposure to dehydration and high salinity stress treatments. There …

Patterns of Evolutionary Conservation and Divergence in the Short-Term Hyposalinity Stress Response of a Euryhaline Diatom, Skeletonema marinoi
… change, requires a successful response to stress. Interspecific differences in stress responses may result in differential survival of species, even within a lineage. Diatoms may constitute one such lineage, as salinity tolerance among extant species is diverse, and the observation of …

A study of salt tolerance in Arabidopsis thaliana and Hordeum vulgare
… this growth impairment arose from osmotic stress or nutrient ion deficiencies. Protein profiling of HHS cells identified a number of proteins whose abundance is regulated by salt stress. These included proteins involved in ion transport, central metabolism, and general stress responses. The …

Characterisation of auxin and auxin-related genes in the response of Arabidopsis thaliana to salt stress
… yield. Salt imposes both an osmotic and ionic stress on plants, and the aim of this study was to investigate the molecular basis of the plant response to the ionic component of salinity stress. To do so, transcriptome profiling using microarrays was performed at two developmental stages (two …

The Role of Arabidopsis thaliana Annexins 1, 2 and 4 in Extracellular ATP Signalling
… plants occurs in response to biotic and abiotic stresses. eATP causes downstream responses such as increase in cytosolic free calcium ([Ca$^{2+}$]$_{cyt}$), reactive oxygen species (ROS), nitric oxide (NO) and phosphatidic acid (PA). The identification of $\it{Arabidopsis}$ $\it{thaliana}$ …

Physiological and Molecular Dissection of Salinity Tolerance in Arabidopsis and Maize and Nitrogen Uptake in Wheat
… the role of this pathway in adaptation to salinity stress in Arabidopsis and maize via physiological and molecular characterization of Arabidopsis prt6-1 and maize prt6 MU insertion mutants, respectively. Our study demonstrated that the loss of function mutation of prt6 in Arabidopsis …

Measuring the Physiological Effects of Methylobacterium oryzae Foliar Inoculation onto Salt-Stressed Tomatoes grown in a Greenhouse Semi-Hydroponic System
<p>Salinity stress has been shown to improve hydroponic produce quality such as that of tomato but at the trade-off of produce yield. In order to improve demand for hydroponic produce, techniques that improve salinity tolerance could offset declines in yield without altering the improved quality of …
