1. A method of decreasing acidity of tomato, the method comprising transforming cells of the plant with a polynucleotide capable of downregulating expression level of a pH gene endogenous to the cells, said pH gene encoding a membrane transporter polypeptide as set forth in SEQ ID NO: 5, said pH gene being capable of modulating acidity of the plant, thereby decreasing the acidity of the plant.
