Improved salt tolerance in a wheat stay-green mutant tasg1
Salt stress inhibited the growth of both tasg1 and wild-type (WT) wheat seedlings, but the inhibition in tasg1 plants was relatively weaker than that of WT. Compared to the WT, the chlorophyll content, thylakoid membrane polypeptides, Hill reaction activity, actual photochemical efficiency of PSII (...

| description | Salt stress inhibited the growth of both
tasg1
and wild-type (WT) wheat seedlings, but the inhibition in
tasg1
plants was relatively weaker than that of WT. Compared to the WT, the chlorophyll content, thylakoid membrane polypeptides, Hill reaction activity, actual photochemical efficiency of PSII (ΦPSII), and Mg
2+
- and Ca
2+
-ATPase activities were higher in
tasg1
under salt stress. At the same time, the photosynthetic activity of the
tasg1
was significantly higher than that of WT. In addition,
tasg1
plants displayed relatively less accumulation of reactive oxygen species and oxidative damage accompanied by higher activity of some antioxidant enzymes, and the up-regulation of antioxidant genes further demonstrated the improvement of antioxidant activity in
tasg1
under salt stress. Furthermore,
tasg1
plants also showed relatively weaker Na
+
fluorescence and lower Na
+
content, but relatively higher content of K
+
in their roots and shoots, and then, the roots of
tasg1
plants enhanced net outward Na
+
flux and a correspondingly increased net inward K
+
flux during salt stress. This might be associated with the relatively higher activity of H
+
-ATPase in
tasg1
plants. These results suggest that the improved antioxidant competence and Na
+
/K
+
ion homeostasis play an important role in the enhanced salinity tolerance of
tasg1
plants. |
