Abstract
A plant promoter that is a nucleic acid region located upstream of the 5' end of a plant DNA structural coding sequence that is transcribed at high levels in meristematic tissue and/or rapidly dividing cells. This promoter region is capable of conferring high levels of transcription in meristematic tissue and/or rapidly dividing cells when used as a promoter for a heterologous coding sequence in a chimetic gene. The promoter and any chimeric gene in which it may be used can be used to obtain transformed plants or plant cells. A DNA coding sequence that codes for a gene that is highly transcribed in meristematic tissue of Arabidopsis thaliana is also disclosed. This coding sequence can be used to obtain a cDNA probe useful in obtaining analogous promoters from a homologous coding sequence in other plant species. Chimeric genes including the isolated promoter region, transformed plants containing the isolated promoter region, transformed plant cells and seeds are also disclosed.
