| 1 | 多环境下野生大豆染色体片段代换系群体农艺性状相关QTL/片段的鉴定显示文摘【目的】改进染色体片段代换系群体,挖掘野生大豆(Glycine soja Sieb.et Zucc.)中蕴藏的农艺性状优异等位变异,为拓宽栽培大豆(Glycine max(L.)Merr.)的遗传基础提供材料和依据。【方法】通过标记加密和剔除部分单标记型片段的方法,改进以野生大豆N24852为供体,栽培大豆NN1138-2为受体的染色体片段代换系(CSSL)群体Soja CSSLP1;对改进后的群体(Soja CSSLP2)进行3年2点田间试验,通过单标记分析、区间作图、完备复合区间作图和基于混合线性模型的复合区间作图等4种定位方法,结合与轮回亲本有显著差异的染色体片段代换系间相互比对,检测与大豆开花期、株高、主茎节数、单株荚数、百粒重和单株粒重相关的野生片段。【结果】改进后的群体(Soja CSSLP2)由150个CSSL构成,其中,有130个家系与Soja CSSLP1相同;在原遗传图谱上,新增40个SSR标记,相邻标记间平均遗传距离由16.15 c M变为12.91 c M,大于20 c M的区段由32个减少至17个,标记覆盖遗传距离总长度较原图谱(2 063.04 c M)增加103.52 c M;群体NN1138-2背景回复率变幅为79.45%—99.70%,平均为94.62%。利用Soja CSSLP2群体,分别鉴定到与开花期、株高、主茎节数、单株荚数、百粒重和单株粒重相关的4、5、5、7、14和3个工作QTL(working QTL)/片段,其中有15个工作QTL/片段能在多个环境下检测到,属共性工作QTL(joint working QTL);除片段Sct_190—Sat_293上的主茎节数位点外,野生等位变异具有的加性效应方向与双亲表型差异方向一致;单个位点分别能解释5%—64%的表型变异;同时,分别检测到3、2和2个与地点存在互作的株高、主茎节数和单株荚数QTL/片段,其中与凤阳环境的互作均具有增加表型的效应,这可能与凤阳较南京所处纬度高有关;这些位点/片段分布在26个染色体片段上,其中有7个片段与2个及以上性状相关,可能是性状相关的遗传基础;与前人结果比较,有3个开花期、3个株高、2个主茎节数、2个单株荚数、8个百粒重、2个单株粒重位点能在其他遗传背景栽培大豆中检测到,说明在这些位点上野生大豆和栽培大豆间及栽培大豆间均存在遗传差异;另外18个位点(片段)为本研究利用野生大豆的新发现。【结论】大豆开花期、株高和主茎节数的遗传基础较百粒重简单,前者均存在效应较大位点/片段,后者多由小效应位点控制,遗传基础极为复杂;野生大豆中蕴藏着新的等位变异,能拓宽栽培大豆遗传基础。 | 向仕华 王吴彬 何庆元 杨红燕 刘成 邢光南 赵团结 盖钧镒 | 2015 | 中国农业科学2015，48，1： | 12 |
| 2 | Orthogonal Test Optimization of Extraction Technology of Total Fla-vonoids from Fruits and Leaves of Prunus mume Sieb. et Zucc. and Its in Vitro Anti-oxidation Activity显示文摘[Objectives]To optimize the extraction technology of total flavonoids component,and investigate its in vitro anti-oxidation activity.[Methods]The single factor was inspected firstly. By orthogonal experiment,the best extraction conditions of total flavonoids from fruits and leaves of P. mume Sieb. et Zucc. were determined,and reducing ability of the extracted total flavonoids and its DPPH and ABTS scavenging abilities were explored. [Results] The best extraction technology conditions: solid-liquid ratio of 1∶ 50,ethanol concentration of 50%,extraction time of 2. 5 h,extraction temperature of 85 ℃,two-time extraction. By detecting DPPH and ABTS scavenging abilities of total flavonoids,the anti-oxidation activity of the total flavonoids from fruits and leaves of P. mume Sieb. et Zucc. was analyzed and evaluated. [Conclusions]Fruits and leaves of P. mume Sieb. et Zucc. had a certain in vitro anti-oxidation activity,and heat reflux extraction method of its total flavonoids had high extraction rate and simple and convenient operation,which had some practical value. | Xue ZHAI Qian JIN Haiyan XIANG Fenglin WANG Yuan LIU | 2017 | Medicinal Plant2017，8，2： | 4 |
| 3 | Genetic Relationships among Prunus mume var. pendula Using AFLP Markers显示文摘Genetic relationships among Prunus mume var. pendula were studied by using AFLP markers. 18 accessions representing 14 cultivars of Prunus mume var. pendula were selected from the germplasm collection at the Research Center of China Mei Flower. Seven Mse I-EcoR I AFLP primer combinations revealed 450 legible bands, and 269 of which were polymorphic markers. A similarity matrix was prepared using the simple matching coefficient of similarity and Neis (72) distance coefficient. A UPGMA dendrogram demonstrated the genetic relationships of the cultivars. The information given by AFLP markers was basically consistent with the morphological classification and the evolutionary history of the morphotypes, and roughly supported the new revised classification system for Chinese Mei Cultivars. But there were still several exceptions: 1) the Guhong Chuizhi inserted between the Tiaoxue Chuizhi and the Danfen Chuizhi; 2) the Wufu Chuizhi kept off the Pink Pendant Form, and the Moshan Chuizhi was removed from Viridiflora Pendant Form; 3) the Danbi Chuizhi and the Shuangbi Chuizhi of Viridiflora Pendant Form got together well but fell within the Pink Pendant Form. | Ming Jun1* Zhang Qixiang2 Ru Guangxin3 Mao Qingshan4 Yan Xiaolan4 Lan Yanping5 1Department of Horticulture, Hubei Agricultural College, Jingzhou 434025, P.
