Changes in gene expression in gills of the euryhaline killifish Fundulus heteroclitus after abrupt salinity transfer.
Maintenance of ion balance requires that ionoregulatory epithelia modulate ion flux in response to internal or environmental osmotic challenges. We have explored the basis of this functional plasticity in the gills of the euryhaline killifish Fundulus heteroclitus. The expression patterns of several genes encoding ion transport proteins were quantified after transfer from near-isosmotic brackis...
متن کاملRole of glucocorticoid receptor in acclimation of killifish (Fundulus heteroclitus) to seawater and effects of arsenic.
Killifish are euryhaline teleosts that adapt to rapid changes in the salinity of the seawater. It is generally accepted that acclimation to seawater is mediated by cortisol activation of the glucocorticoid receptor (GR), which stimulates CFTR mRNA expression and CFTR-mediated Cl- secretion by the gill. Because there is no direct evidence in killifish that the GR stimulates CFTR gene expression,...
متن کاملKey Genes Involved in Wheat Response to Salinity Stress and Mapping their Gene Network
Extended Abstract Introduction and Objective: Considering the importance of salinity in wheat and the multigene nature of this trait, the present study was conducted to investigate the expression of key genes involved in the response of wheat to this stress and to create their network. Material and Methods: In this study, the expression of key genes (HKT, DREB, bZIP, NAC, and WARKY) involved...
متن کاملUsing Transcriptomics to Identify Differential Gene Expression in Response to Salinity among Australian Phragmites australis Clones
Common Reed (Phragmites australis) is a frequent component of inland and coastal wetlands in temperate zones worldwide. Ongoing environmental changes have resulted in the decline of this species in many areas and invasive expansion in others. In the Gippsland Lakes coastal waterway system in south-eastern Australia, increasing salinity is thought to have contributed to the loss of fringing P. a...
متن کاملArsenic exposure to killifish during embryogenesis alters muscle development.
Epidemiological studies have correlated arsenic exposure in drinking water with adverse developmental outcomes such as stillbirths, spontaneous abortions, neonatal mortality, low birth weight, delays in the use of musculature, and altered locomotor activity. Killifish (Fundulus heteroclitus) were used as a model to help to determine the mechanisms by which arsenic could impact development. Kill...
