Abstract

TRR14 is a small protein which is located in chloroplast. This protein was first identified in screening of trehalose resistant (TRR14) Arabidopsis seedlings. The aim of present study was physiological and molecular investigation of TRR14 re-transformed (T17) seedlings under SALT STRESS, compared to wild type Arabidopsis seedlings (WT). For this purpose, WT and T17 seeds were grown on MS medium complemented with 0, 75, 100 and 150 mM NaCl. The results showed that under SALT STRESS, the GERMINATION RATE and TREHALASE activity in T17 seedlings were higher than WT. Meanwhile the results showed that anthocyanin level in WT seedlings was higher than T17 under SALT STRESS. The Na level was highly increased in WT seedlings under 75 mM NaCl treatment, compared to T17 seedlings. The K measurements revealed that the K level in T17 seedling was 3 times more than WT seedling when grown on MS medium. But K level was decreased under 75 mM NaCl treatment in both WT and T17 seedlings. On the other hand, by adding NaCl to medium culture, the shape and size of epidermal cells were changed in both WT and T17 seedlings. While stomata numbers increased in WT leaves under NaCl treatment, it remained unchanged in T17 seedlings. The GENE EXPRESSION pattern showed that TREHALASE and TRR14 expression were increased under SALT STRESS.
