Cloning and Characterization of an Arabidopsis thaliana


cDNA and genomic clones encoding DNA topoisomerase I were isolated from Arabidopsis thaliana Xgtl1 and XFix libraries by low stringency hybridization with a Saccharomyces cerevisiae TOPi probe. The cDNA clones include a 2748-base pair open reading frame predicting an amino acid sequence that is highly homologous to sequences encoded by TOP1 from yeast and… (More)
