Root-specific expression of carbonic anhydrase increases the environmental carbon sequestration ability of plants. Here, a plant is genetically engineered so that its heritable genetic material comprises a gene encoding a transportable carbonic anhydrase protein under the control of a promoter active in root cells, such that the carbonic anhydrase is transported from the roots of the plant into the extracellular environment. These genetically altered plants demonstrate increased levels of carbonic anhydrase activity in the extracellular environment of the plant roots, which enhances carbon sequestration in extracellular environments such as soil.
A plant whose heritable genetic material comprises a gene encoding a transportable carbonic anhydrase protein under the control of a promoter active in root cells, such that the carbonic anhydrase is transported from the roots of the plant into the extracellular environment.
A polynucleotide sequence comprising a sequence coding for a polypeptide sequence under the control of a suitable promoter, wherein the polypeptide sequence comprises a carbonic anhydrase sequence and a signal peptide sequence, wherein the promoter is active in plant roots and capable of driving overexpression of the carbonic anhydrase, the signal peptide sequence being capable of directing transport of the carbonic anhydrase into the extracellular environment of a plant root.
