Abstract:
1. A transgenic plant overexpressing at least one vacuolar pyrophosphatase compared to a wild-type plant of the same plant species, wherein said transgenic plant comprises transgenic plant cells containing an exogenous nucleic acid that causes overexpression of the vacuolar pyrophosphatase in said transgenic plant cells, and wherein said transgenic plant possesses at least one phenotype selected from the group consisting of: increased salt tolerance compared to said wild-type plant, increased drought tolerance compared to said wild-type plant, increased freezing tolerance compared to said wild-type plant, increased meristematic cell division compared to said wild-type plant, increased biomass compared to said wild-type plant, altered root morphology compared to said wild-type plant, improved shoot regeneration compared to said wild-type plant, and enhanced water retention capability compared to said wild-type plant.
