Abstract

Transgenic plants are described which are engineered to overexpress vacuolar H+-PPase. Plants such as tobacco and petunia transformed with A. Thaliana AVP-1 are shown to have increased meristematic activity resulting in larger leaves, stem, flower, fruit, root structures, increased salt tolerance, enhanced drought and freeze tolerance. Methods of making such plants are also described.
