VACUOLAR PYROPHOSPHATASES AND USES IN PLANTS

摘要

The present invention relates to a transgenic plant which is tolerant to a salt, comprising one or more plant cells transformed with exogenous nucleic acid which alters expression of vacuolar pyrophosphatase in the plant. The present invention also relates to a transgenic plant with increased Pi uptake, comprising one or more plant cells transformed with exogenous nucleic acid which alters expression of vacuolar pyrophosphatase in the plant. Also encompassed by the present invention are transgenic progeny and seeds of the transgenic plants described herein. Progeny transgenic plant grown from seed are also described. Plant cells (e.g., root cells, stem cell, leaf cells, flower cells, fruit cells and seed cells) comprising exogenous nucleic acid which alters expression of vacuolar pyrophosphatase in the plant cell are also the subject of the present invention. Also encompassed by the present invention are methods of making a transgenic plant described herein. Transgenic plants produced by the methods of making a transgenic plant as described herein are also a subject of the present invention. The present invention also relates to a method of bioremediating soil, a method of increasing the yield of a plant, a method of making a plant which is larger than its corresponding wild type plant, a method of producing a transgenic plant which grows in salt water, and a method of producing a transgenic plant with increased Pi uptake. The transgenic plants of the present invention can also be used to produce double transgenic plants which are tolerant to a salt, or have increased Pi uptake.
