Abstract
Vacuolar H+-ATPase (VHA) as one of plant proton pumps in the tonoplast plays a very important role in plant growth and stress tolerances. In this paper, we reported that expression of the apple (Malus domestica B.) vacuolar H+-ATPase subunit A (MdVHA-A) was induced by salt stress in apple in vitro shoot cultures. Additionally, MdVHA-A overexpression enhanced the resistance to salinity in the transgenic tobacco (Nicotiana tabacum L.) plants. Compared to control tobacco plants, the transgenic plants exhibited the higher Na+, K+, and proline content but lower MDA content in leaves and roots. Therefore, these results indicate that expression of MdVHA-A can enhance plant tolerance to salt stress by modulating internal stores of ions and solutes.
