Abstract
The ionic transport systems have important roles on the ionic homeostasis in the cells under the salt stress. We hardly know about intracellular behavior of chloride ions, a counter ion for sodium ions, under the high salt condition. It was reported that AtCLC-a and -c play a role in controlling the intracellular nitrate status in Arabidopsis. However, other functions were not known. We investigated about the two chloride channel genes, OsCLC-1 and OsCLC-2in rice. To assess the function of rice chloride channel genes OsCLC-1 and -2, we isolated deletion mutants from a panel of rice mutants produced by the insertion of a retrotransposon, Tos17. clc-1 and clc-2 had slightly reduces root length compared with wild type. Therefore, we investigate the morphology of roots from clc-1, clc-2, and the double mutant of them in detail.
