ABSTRACT
Wheat vacuolar H-ATPases (V-ATPase) subunit B, named TaVB, was isolated from the salt-tolerant wheat RH8706-49 and used to transform Arabidopsis plants. TaVB-expressed Arabidopsis has a higher germination rate, root length, V-H-ATPase activity, and overall salt tolerance than the wild type, indicating that expression of the gene can affect salt tolerance of the transgenic plants. Under salt stress, intracellular Na levels in transgenic plants are significantly lower than the control. These results suggest that expression of the wheat TaVB gene may enhance plant tolerance to salt stress.
