摘要: 研究了9种泡桐叶片蛋白质的多态性,并根据其叶片蛋白质聚丙烯酰胺凝胶单向和双向电泳结果,将它们聚类为白花泡桐组[白花泡桐(Paulownia fortunei)和白花兰考泡桐(P. elongata f. alba)]、南方泡桐组[南方泡桐(P. australis)和成都泡桐(P. albiphloea var. chengtuensis)]和毛泡桐组[毛泡桐(P. tomentosa)、川泡桐(P. fargesii)、鄂川泡桐(P. albiphloea)、山明泡桐(P. lamprophylla)和兰考泡桐(P. elongata )]。该结果可为了解泡桐属植物的亲缘关系和种的鉴定提供参考依据。

Abstract: This paper deals with protein polymorphism in 9 taxa of Paulownia plant leaves and relationship among them. The results indicated that the 9 taxa may be divided into three groups: Paulownia australis group (Paulownia australis and P. albiphloeavar. chengtuensis), Paulownia fortunei group (P. fortunei andP.elongata f. alba) and Paulownia tomentosa group (P. tomentosa, P. fargesii, P. albiphloea, P. lamprophylla and P.elongata)based on one-and two_dimensional sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS_PAGE )of proteins in those plant leaves, which provided evidence for classification of the genus and identification of lower taxa.
