| 摘 要： | 目的]探索一种适合荞麦的简单易行的染色体原位PCR技术。方法]采用16S套式引物、4．5S套式引物与psbA引物，以栽培甜荞为材料，进行染色体原位PCR、原位套式PCR与多次原位PCR试验。结果]高温干燥可以起到与包埋类似的作用；染色体的原位套式PCR效果比原位PCR明显，多次原位PCR次数为5-6效果较佳。16S引物和4．5S引物均显示了4对信号，但位置不同；而psbA引物是单拷贝的，仅显示出1对信号。根据这些信号的位置差异可以区分普通荞麦的5对染色体。结论]所使用的荞麦染色体原位PCR技术简单易行。

| Abstract: | Objective] The paper aimed to explore a simple in-situ PCR technology for buckwheat. Method] Common buckwheat was taken as experimental material. By using 16S and 4.5S nested primers and psbA primer, the in-situ PCR, nested in-situ PCR and multiple in-situ PCR were carried out respectively. Result] High-temperature drying treatment had the effects similar to that of embedding methods. The effect of the nested in-situ PCR is better than that as usual. A better result could be obtained when the multiple in... |
