报道了用ＱｉａｇｅｎＫｉｔ纯化ＲＡＰＤ遗传标记，用细菌质粒Ｍ１３克隆ＲＡＰＤ标记的ＤＮＡ片段，采用自动荧光ＤＮＡ测序仪（型号３７３Ａ）测定了该ＤＮＡ片段的核苷酸组成及其排列顺序。无核白ＲＡＰＤ标记由５１９对核苷酸及其特定序列组成。因为无核白是无核基因的原始供体，作者认为所获无核白ＲＡＰＤ标记的ＤＮＡ序列，可以作为合成探针的基础，用于检测无核葡萄育种和无核品种的无核性。 Reported the purification of RAPD genetic markers with Qiagen Kit, the cloning of RAPD-labeled DNA fragments with bacterial plasmid M13 and the determination of the nucleotide composition and arrangement of the DNA fragments using an automated fluorescent DNA sequencer (Model 373A). Nucleotide-free RAPD markers consist of 519 pairs of nucleotides and their specific sequences. Since apheresis is the original donor of a nuclear-free gene, the authors conclude that the DNA sequence of the aptamer-free RAPD marker can be used as a basis for a synthetic probe for the detection of seedless grapes and non-nuclear non-nuclear species.
