Carboxymethytl pachymaram (CMP) was administered to HBV transgenic mice through abdominal injection. Lymphocytes were extracted from the spleens. MTT method was used to detect cytotoxicity of CMP. Dendritic cells (DCs) were separated from lymphocytes and incubated with granulocyte-macrophage colony-stimu-lating factor (GM-CSF) and interleukin-4 (IL-4). Phenotypes of DC’s were assayed by flow cytometry (FCM). IL-12 released by DCs and IL-10 and IFN-γ pro-duced by T cells in mixed lymphocyte reaction (MLR) were measured using ELISA. Results showed that CMP within the concentration of 0-500μg/mL did not produce cyto-toxicity to lymphocytes and could even increase DC phe-notypes, and IL-12 level in HBV transgenic mice. It could also increase the secretion of IFN-γ, and inhibit the secre-tion of IL-10 in MLR. Thus it can up-regulate DC function.

中国是烟草种质资源大国,目前中国烟草种质资源平台保存烟草种质资源5300多份,独家保存量居世界首位。庞大的资源数量给烟草种质的保存、评价、研究以及利用带来许多不便。烟草核心种质的构建对促进烟草种质资源的进一步收集保存、优异种质挖掘以及烟草遗传育种均具有非常重要的意义。核心种质构建的关键是准确地评价不同材料间的遗传差异以及合理的抽样策略,本研究从烟草农艺性状着手,比较不同构建方法所得核心子集的遗传多
