Cytological and molecular biological evidence for taxonomic revision of Paeonia delavayi
-
摘要: 滇牡丹Paeonia delavayi是中国西南地区特有种,其分类一直存在争议。回顾了滇牡丹的分类历史和分类处理,综述了滇牡丹在细胞学及分子生物学的研究现状及进展,着重介绍了滇牡丹的染色体核型、Giemsa C-带、同工酶生化标记、分子标记及基因序列测定等研究成果,认为染色体核型、Giemsa C-带、同工酶生化标记、分子标记等结果支持将滇牡丹复合群归并为滇牡丹一个种的分类处理,基因序列分析只涉及滇牡丹的2个居群,认为二者亲缘关系很近。表1参42Abstract: The taxonomy of Paeonia delavayi,an endemic species to Southwestern China,is controversial. The taxonomic history and revision of P. delavayi were reviewed and recent advances on cytology and molecular biology were reviewed. Then,a gene sequence analysis was carried out on two populations of P. delavayi,and karyotypes,Giemsa C-bandings,isozyme biochemical markers,and DNA molecular markers analysis supported the composite group of P. delavayi merging into one species. Results showed that the karyotypes,Giemsa C-bandings,isozyme biochemical markers,and DNA molecular markers could become taxonomic evidence of P. delavayi. Further research was suggested.[Ch,1 tab. 42 ref.]
