Salinity is an increasing problem for agricultural production worldwide. The result of low-affinity Na uptake is toxic to the cytoplasm of most crop plants. Nevertheless, the pathways for this low-affinity Na uptake are still uncertain. In this work we used Na isotope tracing technology to investigate factors associated with determination of root Na influx in the salt accumulation halophyte Suaeda maritima. We found that a 2 min of exposure to the Na labeled uptake solution was optimal for determining Na influx into excised roots of S. maritima and that 7 min of blotting is suitable in Na influx experiments. Na influx did not increase linearly with the increasing external Na concentration, in the range tested, of 2 to 300 mM NaCl. But root Na influx and root Na concentration were well correlated. Na influx into excised roots of S. maritima was not, however, well correlated with the plant size. All the above results indicated further that this Na isotope influx procedure is a good method for quantify Na uptake rate by the roots of the salt accumulation halophyte. [ABSTRACT FROM AUTHOR] |
