Abstract
The present invention relates to the isolation, purification, characterization and use of a mitochondrial pyruvate dehydrogenase kinase (PDHK) gene [SEQ ID NO:1](pYA5; ATCC No 209562) from the Brassicaceae (specifically Arabidopsis thaliana). The invention includes isolated and purified DNA of the stated sequence and relates to methods of regulating fatty acid synthesis, seed oil content, seed size/weight, flowering time, vegetative growth, respiration rate and generation time using the gene and to tissues and plants transformed with the gene. The invention also relates to transgenic plants, plant tissues and plant seeds having a genome containing an introduced DNA sequence of SEQ ID NO:1; or a part of SEQ ID NO:1 characterized in that said sequence has been introduced into an antisense or sense orientation, and a method of producing such plants and plant seeds. The invention also relates to substantially homologous DNA sequences from plants encoding proteins with deduced amino acid sequences of 25% or greater identity, and 50% or greater similarity, isolated and/or characterized by known methods using the sequence information of SEQ ID NO:1, and to parts of reduced length that are…
