Title

Other claims from this paper (7)
- Method / resource A barley HvProT cDNA was cloned from salt-stressed roots.
- Observation HvProT is 2,161 bp and encodes 450 amino acids.
- Intervention effect HvProT root transcript rose after NaCl treatment at 30 min and peaked at 3 h.
- Intervention effect Leaf HvProT transcript stayed very low and did not rise with salt stress.
- Observation HvProT transported L-proline with high affinity, Km 25 microM.
- Mechanism HvProT transport depended on the pH gradient, suggesting a H(+)/amino acid symporter.
- Observation HvProT mRNA was strongly expressed in salt-stressed root cap cells.
