In a previous study we constructed a physical map of the chloroplast DNA (ctDNA) of garden asparagus (Asparagus officinalis L. cv 'Mary Washington 500W'; Lee et al. 1996). In the present study we have constructed and compared HindIII and XhoI restriction maps of the ctDNAs of eight species of Asparagus: namely, A. officinalis, A. schoberioides, A. coehinchinensis, A. plumosus, A. falcatus, A. sprengeri, A. virgatus and A. asparagoides. The ctDNA of A. officinalis has 32 and 23 sites that are recognized by HindIII and XhoI, respectively. Taking the physical map of the ctDNA of A. officinalis as a standard, we found that the ctDNAs of A. falcatus, A. sprengeri, and A. asparagoides each had one additional HindIII site and lacked one XhoI site. We also detected two relatively large deletions of nucleotides in the ctDNA from A. cochinchinensis by sequencing analysis. Both of these deletions were located in a non-coding region between the ndhC and trnV genes and were 95 bp and 347 bp in length, respectiveIy. The regions around the deletions exhibited strong homology, and short direct-repeat sequences were detected at the borders of the deletions, an indication that these deletions were the result of intramolecular recombination mediated by the direct repeats.
