Northern blotting analysis showed that the gene, named as AtITL1, is strongly induced by NaCl and low temperature, but not induced by drought and abscisic acid (ABA). Analysis of 5′ region of the AtITL1 found that there are dehydration_responsive element/C_repeat (DRE/CRT) cis _acting elements, but no elements related to G_box and ABRE (ABA_responsive element) in its 5′ region, which is consistent with the expression patterns of the AtITL1 independent of ABA. These results suggest that the AtITL1 may be involved in the osmotic stress response pathway independent of ABA.展开更多
