We have studied the DNA of Allium sativum L. with respect to highly repetitive sequences. Fast reassociated DNA fragments expected to be highly repetitive sequences based on $C_{o}t$ curve were isolated and characterized. Their copy numbers were approximately $10^{5}~10^{7}$ per haploid genome. Nucleotide sequences analysis of six candidates reveals that their G/C content were low, 25-40% and typical patterns of repeating sequences exist. Repeat sequences were used as probes to access restriction fragment length polymorphism (RFLP) of genomic DNAs of four local clones, Tanyang, Mungyong, So san, and Uisong. The hybridization pattern were very similar among these four local clones.clones. |
