Abstract Sea level rise is a worldwide concern as high percentage of the population located in coastal areas. The focus this study impact sea Guadiana Estuary, an estuary Iberian Peninsula formed at interface River and Gulf Cadiz. Estuaries will be impacted by these transitional environments host highly diverse complex marine ecosystems. major consequences are intrusion salt from into fresh wat...
Salinity is a common abiotic stress during the cotton growing season. Salinity stress causes a series of negative effects on cotton growth, yield, and fiber quality. Although cotton is considered as moderately sensitive to saline with a . dS m-1 threshold salinity level, its yield, quality, and seed germination are affected by different salinity levels. Therefore, identification of salt-toleran...
In this study, the effects of salinity stress (NaCl) on the activity of Catalase (CAT), Guaiacol Peroxidase (POD), and Superoxide dismutase (SOD) were studied in leaves of fifteen oilseed rape (Brassica napus L.) cultivars (Champlain, Hayola401, Licord, Modena, NK Aviator, NK Karibik, NK Octan, Okapy, Opera, PF, RGS, RNX 3621, SLM046, Talayeh, Zarfam). Plants were grown in a greenhouse under co...
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...
BACKGROUND Low salinity is one of the main factors limiting the distribution and survival of marine species. As a euryhaline species, the Pacific oyster Crassostrea gigas is considered to be tolerant to relative low salinity. The genes that regulate C. gigas responses to osmotic stress were monitored using the next-generation sequencing of whole transcriptome with samples taken from gills. By R...
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 ...
WHIGHAM, D. F., T. E. JORDAN AND J. MIKLAS (Smithsonian Environmental Research Center, Box 28, Edgewater, MD 21037). Biomass and resource allocation of Typha angustifolia L. (Typhaceae): The effect of within and between year variations in salinity. Bull. Torrey Bot. Club 116: 364-370. 1989.-In a brackish wetland dominated by Typha angustifolia, we found similar aboveground and belowground produ...
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...
