【摘要】：叶绿体普遍存在于绿色植物中,ycf15基因位于叶绿体基因组IR区,长度一般为250~550 bp,高度保守,目前对该基因研究较少。就有限的研究成果来看,其独特的序列结构及其显现的丰富多样的遗传信息不仅具有一定的物种鉴定意义,而且在植物系统进化分析研究中有较大的潜力。同时,ycf15基因具有保守性高、片段长度较小、无需克隆测序等特点,在进一步构建中药材鉴定DNA条形码中具有独特优势。从ycf15基因的结构特点、物种鉴定与系统学意义几方面进行梳理并展望其在药用植物鉴定中的应用前景。
[Abstract]:Chloroplast is commonly found in green plants in the chloroplast genome IR region, the length of which is usually 250 ~ 550 BP, highly conserved, so far little research has been done on this gene. According to the limited research results, its unique sequence structure and its abundant and diverse genetic information not only have some significance in species identification, but also have great potential in plant phylogenetic analysis. At the same time, it has the characteristics of high conservation, small fragment length and no need for cloning and sequencing, so it has unique advantages in further construction of DNA bar code for identification of Chinese medicinal materials. The structural characteristics, species identification and systematics significance of ycf15 gene were reviewed and its application prospect in identification of medicinal plants was prospected.
