By varying all combinations of developmental stages and pulse exposures of zebrafish embryos, effect of salinity (S) was examined. Zebrafish embryos survived until hatching at 2‰ S alone. Tolerance to salinity increased with advancing developmental stage, i.e. the gastrulae were more tolerant to salinity change than the blastulae and the blastulae were more tolerant than the cleaving embryos. C...

To characterize and dissect genetic variation for salinity tolerance, we assessed variation in salinity tolerance during germination and seedling growth for a worldwide sample of Arabidopsis thaliana accessions. By combining QTL mapping, association mapping and expression data, we identified genomic regions involved in salinity response. Among the worldwide sample, we found germination ability ...

(Typhaceae): The effect of within and between year variations in salinity. Bull. Torrey Bot.

Among abiotic stresses, high salinity stress is the most severe environmental stress, which impairs crop production on at least 20% of irrigated land worldwide. In response to high salinity stress, various genes get upregulated, the products of which are involved either directly or indirectly in plant protection. Some of the genes encoding osmolytes, ion channels, receptors, components of calci...

The effects of shading in combination with salinity treatments were studied in citrus trees on two rootstocks with contrasting salt tolerance to determine if shading could reduce the negative effects of salinity stress. Well-nourished 2-year-old 'Valencia' orange trees grafted on Cleopatra mandarin (Cleo, relatively salt tolerant) or Carrizo citrange (Carr, relatively salt sensitive), were grow...

The Apalachicola Bay is one of the most productive estuaries in Florida. Variations of salinity directly influence the productivity of the aquatic habitats. Physical conditions that affect the salinity include tidal elevations, wind and current velocities, precipitation, and the discharge of the Apalachicola River. In the present paper, cross-correlation techniques, autoregressive integrated mo...

in this study the effects of water salinity on serum total protein and its components in grass carp were investigated. the aim of this study was to determine the effect of salinity tolerance of fish on total serum protein level and its components as an indicator of liver and kidney activity. one hundred and twenty grass carp were divided into four groups, randomly. the first three groups were r...

Zygophyllum simplex L. is a succulent annual that grows on the coastal and inland saline flats around Karachi, Pakistan. The seeds are moderately salt tolerant during germination. Germination of Zygophyllum simplex seeds under various salinity, proline, betaine, GA and kinetin treatments was determined. Proline (0±1 and 1 m) and betaine (0±1 and 1 m) alleviated the innate dormancy of seeds, a...

A contrasting trend pattern of sea surface salinity (SSS) between the western tropical Pacific (WTP) and the southeastern tropical Indian Ocean (SETIO) is observed during 2004-2013, with significant salinity increase in the WTP and freshening in the SETIO. In this study, we show that increased precipitation around the Maritime Continent (MC), decreased precipitation in the western-central tropi...

Arbuscular mycorrhiza is a mutualistic association between fungi and higher plants, and play a critical role in nutrient cycling and stress tolerance. However, much less is known about the mycorrhiza-mediated enhancement in growth and salinity tolerance of the peanuts (Arachis hypogaea L.) growing in the arid and semi-arid areas. Therefore, mycorrhizal status of Glomus mosseae in diverse salini...
