摘  要:
木棉科为锦葵目的一科,该科中很多植物具有药用及其他重要的经济价值。本研究以水稻品种日本晴为内标,采用流式细胞仪,首次测定了两种木棉科植物木棉和瓜栗的基因组大小(2C DNA含量)。测定结果表明,木棉的基因组大小(2C DNA含量)平均为1.55±0.03 pg,瓜栗的基因组大小(2C DNA含量)平均为3.21±0.075 pg。测定结果为木棉科植物相关基因组学以及系统进化研究提供了参考依据。

摘  要:
Many plants of Bombacaceae,which belong to Malvales,have important medicinal and other economic values. Using rice( Oryza sativa var. Nipponbare) as an internal standard,the genome sizes( the content of 2C DNA) of Bombax malabaricum and Pachira macrocarpa were determined by flow cytometry for the first time. The results showed,the average genome sizes of B. malabaricum and P. macrocarpa were about 1. 55 ± 0. 03 pg and 3. 21 ± 0. 075 pg,respectively,and the results provides basic date for further study on relevant genomics and system evoluation for Bombacaceae plants.
