【摘要】 寡核苷酸荧光原位杂交技术是一种整合了生物信息学分析、DNA高通量合成以及荧光原位杂交实验的新兴技术。该技术适用于任何具有参考基因组的植物物种,并可根据研究需求设计靶向某个染色体区域、整条染色体或一组染色体的寡核苷酸探针,目前已成功应用于数种植物的核型分析、染色体变异、种群演化、同源染色体配对、单倍型分析和异源多倍体识别等研究。该文详述了植物寡核苷酸探针的设计、扩增和标记、染色体制备以及荧光原位杂交的具体操作流程,以期促进寡核苷酸荧光原位杂交技术在细胞遗传学研究中的应用。更多还原

【Abstract】 Oligonucleotide fluorescence in situ hybridization(Oligo-FISH) is a new technology that integrates bioinformatics analysis, high throughput DNA synthesis and fluorescence in situ hybridization experiments. It is applicable to plant species with a reference genome. Oligo probes are able design to a chromosomal region, an entire chromosome, and a set of chromosomes according to researchers’ requirements. Oligo-FISH has been successfully applied to studies on karyotyping, chromosome variation, population evolution, homologous chromosome pairing, haplotype analysis, and heteropolyploid identification in several plant species. Here, we introduce the concrete operational processes of oligonucleotide-based probe design, amplification and labeling, chromosomes preparation, and fluorescence in situ hybridization in plants, so as to facilitate Oligo-FISH application in the cytogenetics research in the future.更多还原
