Patent ID: 7534933

Claim:
A method of making a transgenic plant with one or more enhanced phenotypic traits relative to non-transgenic wild-type plants of the same species, wherein the one or more enhanced phenotypic traits are selected from the group consisting of: increased biomass in one or more plant parts, increased shoot regeneration, increased root regeneration, and enhanced callus induction, said method comprising: a) introducing exogenous nucleic acid encoding a plant vacuolar pyrophosphatase into cells of a plant to generate transformed cells, wherein the exogenous nucleic acid is operably linked to at least one regulatory element that causes overexpression of plant vacuolar pyrophosphatase in the transformed cells; b) regenerating transgenic plants from the transformed cells; and c) selecting for a transgenic plant with one or more enhanced phenotypic traits relative to non-transgenic wild-type plants of the same species, wherein the one or more enhanced phenotypic traits are selected from the group consisting of: increased biomass one or more plant parts, increased shoot regeneration, increased root regeneration, and enhanced callus induction.
