Isolation and characterization of a plasma membrane Na/H antiporter gene TaSOS1 from wheat
نویسندگان
چکیده
We have cloned TaSOS1 gene from Triticum aestivum L.which encodes a plasma membrane Na/H antiporter. TaSOS1 encodes a polypeptide of 1,142 amino acid residues with a theoretical molecular mass of 126 kDa. TaSOS1 protein is a plasma membrane-bound protein which enhanced Na and Li tolerance when overexpressed in yeast salt sensitive mutants. TaSOS1 transcripts were detected in all investigated tissues, including roots, shoots, spikes and anthers and was upregulated by both ABA and salt. Those results indicate TaSOS1 may play an important role in salt stress response in common wheat.

Assessment of the vacuolar Na+/H+ antiporter (NHX1) transcriptional changes in Leptochloa fusca L. in response to salt and cadmium stresses
Sodium/proton exchangers (NHX) are key players in plant responses to salinity and have a central role in establishing ion homeostasis. NHXs can be localized in tonoplast or plasma membranes, where they exchange sodium ions for protons, resulting in the removal of ions from the cytosol into vacuole or extracellular spaces. In the present study, the expression pattern of the gene encoding Na+/H+ ...
متن کاملImproved salt tolerance in canola (Brasica napus) plants by overexpression of Arabidopsis Na+/H+ antiporter gene AtNHX1
A significant portion of the world’s cultivated land is affected by salinity that reduces crop productivity in these areas. Breeding for salt tolerance is one of the important strategies to overcome this problem. Recently, genetic engineering is becoming a promising approach to improving salt tolerance. In order to improve the yield performance of canola in saline soils, we transformed canola w...
متن کاملHeterologous expression of Na+/H+ antiporter gene (CvNHA1) from salt-tolerant yeast Candida versatilis in Saccharomyces cerevisiae Na+-transporter deficient mutants.
A Na(+)/H(+) antiporter gene (CvNHA1) was cloned from the salt-tolerant yeast Candida versatilis. CvNHA1 encodes an antiporter with a typical yeast plasma membrane Na(+)/H(+) antiporter structure. Transcription of CvNHA1 in C. versatilis cells was dependent on the salinity of the culture. When CvNHA1 was expressed in salt-sensitive Saccharomyces cerevisiae cells, increased salt-tolerance was ob...
متن کاملCharacterization of the ion transport activity of the budding yeast Na+/H+ antiporter, Nha1p, using isolated secretory vesicles.
The Saccharomyces cerevisiae Nha1p, a plasma membrane protein belonging to the monovalent cation/proton antiporter family, plays a key role in the salt tolerance and pH regulation of cells. We examined the molecular function of Nha1p by using secretory vesicles isolated from a temperature sensitive secretory mutant, sec4-2, in vitro. The isolated secretory vesicles contained newly synthesized N...
متن کاملUp-regulation of plasma membrane H+-ATPase under salt stress may enable Aeluropus littoralis to cope with stress
Plasma membrane H+-ATPase is a major integral membrane protein with a role in various physiological processes including abiotic stress response. To study the effect of NaCl on the expression pattern of a gene encoding the plasma membrane H+-ATPase, an experiment was carried out in a completely random design with three replications. A pair of specific primers was designed based on the sequence o...
