dc.description.abstract | Salinity stress is a major factor inhibiting cereal yield
throughout the world. Tolerance to salinity stress can be
considered to contain three main components: Na+ exclusion,
tolerance to Na+ in the tissues and osmotic tolerance.
To date, most experimental work on salinity tolerance in
cereals has focused on Na+ exclusion due in part to its ease
of measurement. It has become apparent, however, that Na+
exclusion is not the sole mechanism for salinity tolerance
in cereals, and research needs to expand to study osmotic
tolerance and tissue tolerance. Here, we develop assays for
high throughput quantification of Na+ exclusion, Na+ tissue
tolerance and osmotic tolerance in 12 Triticum monococcum
accessions, mainly using commercially available image
capture and analysis equipment. We show that different
lines use different combinations of the three tolerance
mechanisms to increase their total salinity tolerance, with a
positive correlation observed between a plant’s total salinity
tolerance and the sum of its proficiency in Na+ exclusion,
osmotic tolerance and tissue tolerance. The assays developed
in this study can be easily adapted for other cereals
and used in high throughput, forward genetic experiments
to elucidate the molecular basis of these components of
salinity tolerance. | en_US |
