A MODIFIED ARABIDOPSIS THALIANA CAC1, CAC2 OR CAC3 PROMOTER AND AN ARABIDOPSIS THALIANA CAC1, CAC2 OR CAC3 SUPPRESSOR ELEMENT AND METHODS OF USE THEREOF
A MODIFIED ARABIDOPSIS THALIANA CAC1, CAC2 OR CAC3 PROMOTER AND AN ARABIDOPSIS THALIANA CAC1, CAC2 OR CAC3 SUPPRESSOR ELEMENT AND METHODS OF USE THEREOF
The present invention provides a modified Arabidopsis thaliana CAC1, CAC2 or CAC3 promoter, the Arabidopsis thaliana CAC1, CAC2 or CAC3 suppressor element, a recombinant vector comprising such a modified promoter or such a suppressor element, a host cell comprising such a recombinant vector, methods of using the modified promoter or the suppressor element to regulate or suppress, respectively, expression of a coding sequence in a cell, a plant cell in which the expression of a coding sequence in the plant cell has been so regulated or suppressed, as well as a plant tissue, a plant organ and a plant comprising such a plant cell. Also provided by the present invention is an isolated or purified nucleic acid molecule comprising the genomic DNA sequence of the carboxyltransferase α subunit (CAC3) of the acetyl CoA carboxylase (ACC), a vector comprising such a sequence, a cell transformed with such a vector, a plant cell, a plant tissue, a plant organ or a plant in which the level of a subunit of ACC, ACC enzymatic activity or malonyl CoA has been altered, and a method of producing such a plant cell, plant tissue, plant organ or plant.
