Salt acclimation induced salt tolerance in wild-type and chlorophyl b-deficient mutant wheat

Use of wild relatives to improve salt tolerance in wheat.

There is considerable variability in salt tolerance amongst members of the Triticeae, with the tribe even containing a number of halophytes. This is a review of what is known of the differences in salt tolerance of selected species in this tribe of grasses, and the potential to use wild species to improve salt tolerance in wheat. Most investigators have concentrated on differences in ion accumu...

Arabidopsis sos1 mutant in a salt-tolerant accession revealed an importance of salt acclimation ability in plant salt tolerance

An analysis of the salinity tolerance of 354 Arabidopsis thaliana accessions showed that some accessions were more tolerant to salt shock than the reference accession, Col-0, when transferred from 0 to 225 mM NaCl. In addition, several accessions, including Zu-0, showed marked acquired salt tolerance after exposure to moderate salt stress. It is likely therefore that Arabidopsis plants have at ...

Salt Tolerance and Salt Poisoning of Swine

COMMON SALT is recognized as one of the chemical substances required in the diet of animals; hence it is good husbandry to include a supply in the rations of livestock. The quantitative requirements vary with the species. Those for swine are regarded as among the lowest. That excessive aniounts may be harmful to the extent of being toxic is not at all surprising, since there are recognized limi...

Osmoadaptation in rhizobia: ectoine-induced salt tolerance.

After having shown that ectoine (a tetrahydropyrimidine) displays osmoprotective properties towards Escherichia coli (M. Jebbar, R. Talibart, K. Gloux, T. Bernard, and Blanco, J. Bacteriol. 174:5027-5035, 1992), we have investigated the involvement of this molecule in the osmotic adaptation of Rhizobium meliloti. Ectoine appeared almost as effective as glycine betaine in improving the growth of...
