中文摘要:
      以买麻藤(Gnetum montanum)为内参,测定5种常用裂解液(Tris?MgCl2、LB01、WPB、Otto’s、Galbraith’s)对桫椤(Alsophila spinulosa)细胞核的裂解效果,并通过比较桫椤和买麻藤流式细胞仪测定的荧光峰值,计算出桫椤的基因组大小。结果表明:5种裂解液中,WPB为桫椤最佳裂解液;桫椤基因组大小为6 003.25 Mb,即2C DNA含量为6.138 pg。
英文摘要:
      In this study, to find out the optimal lysis buffer for dissociating cell nucleus, five common lysis buffers (Tris?MgCl2, LB01, WPB, Otto’s, Galbraith’s) were tested on the cell nucleus of Alsophila spinulosa leaves by use of Gnetum montanum as internal standard, and, the genome size of A. spinulosa was calculated according to the multiple relationships of peak values of A. spinulosa and Gnetum montanum using flow cytometry. The results showed that the WPB was the most appropriate lysis buffer to dissociate A. spinulosa cell nucleus and the genome size of A. spinulosa was determined to be 6 003.25 Mb, i.e. 2C DNA content was 6.138 pg.
