Materials and methods for the alteration of enzyme and acetyl CoA levels in plantsIowa State University Patents
AbstractThe present invention provides nucleic acid and amino acid sequences of acetyl CoA synthetase (ACS), plastidic pyruvate dehydrogenase (pPDH), ATP citrate lyase (ACL),Arabidopsis pyruvate decarboxylase (PDC), and Arabidopsis aldehyde dehydrogenase (ALDH), specifically ALDH-2 and ALDH-4. The present invention also provides a recombinant vector comprising a nucleic acid sequence encoding one of the aforementioned enzymes, an antisense sequence thereto or a ribozyme therefor, a cell transformed with such a vector, antibodies to the enzymes, a plant cell, a plant tissue, a plant organ or a plant in which the level of an enzyme has been altered, and a method of producing such a plant cell, plant tissue, plant organ or plant. Desirably, alteration of the level of enzyme results in an alteration of the level of acetyl CoA in the plant cell, plant tissue, plant organ or plant. In addition, the present invention provides a recombinant vector comprising an antisense sequence of a nucleic acid sequence encoding pyruvate decarboxylase (PDC), the E1α subunit of pPDH, the E1β subunit of pPDH, the E2 subunit of pPDH, mitochondrial pyruvate dehydrogenase (mtPDH) or aldehyde dehydrogenase (ALDH) or a ribozyme that can cleave an RNA molecule encoding PDC, E1α pPDH, E1β pPDH, E2 pPDH, mtPDH or ALDH.
