分枝数是大豆重要的农艺性状,与大豆株型结构、产量潜力和适应性密切相关。为挖掘大豆分枝数稳定遗传位点,本研究以多分枝大豆Charleston和主茎型大豆东农594为亲本构建的148份重组自交系群体(RILs)和以主茎型大豆绥农14和多分枝野生大豆ZYD00006为亲本构建的213份染色体片段代换系(CSSLs)2个遗传群体为试验材料,采用ICIMapping软件中的完备区间作图法(inclusive composite interval mapping,ICIM)和Win-QTL-Cart 2.5软件中的复合区间作图法(composite interval mapping,CIM),对2018-2021年两个遗传群体的分枝数表型数据进行QTL分析,对QTL置信区间内的候选基因进行挖掘。共检测到17个与大豆分枝数性状相关的QTL位点,其中qBNA2_1和qBNK_1在不同年份和不同群体中稳定出现,分布在第8和9号染色体。根据基因注释等信息对两个QTL区间内的候选基因进行筛选,并通过qRT-PCR预测Glyma.08G053700、Glyma.08G068200、Glyma.08G082400和Glyma.09G167100为调控分枝数的候选基因。本研究结果有助于探明大豆分枝数形成的遗传机制,为大豆理想株型研究提供候选基因与材料支撑。

作者： DONG Ping LIN Ji-Cheng yang ming CAO Zhuo-liang School of Physics and Material Science Anhui University Hefei 230039 China

We propose a probabilistic scheme for realizing teleportation of bipartite photonic states using linear optical elements where only requires a two-photon Bell state used as quantum channel. It reduces the requirement of the entanglement of quantum channel, but requires an additional photon and an auxiliary maximally entangled photon pair locally.

Journal of Integrative Agriculture 2013年第3期12卷 406-413页

作者： HUANG Shan-shan LI Chang-suo yang ming-liang LI Wen-bin WANG Ji-an Key Laboratory of Soybean Biology Ministry of Education/Soybean Research Institute Northeast Agricultural University Plant Protection Institute Heilongjiang Academy of Land Reclamation Sciences

To study the relationships between C4 enzyme activities and yield, C4 enzyme activities （phosphoenolpyruvate carboxylase （PEPCase）, NADP-malate dehydrogenase （NADP-MDH）, NADP-malic enzyme （NADP-ME）, and pyruvate phosphate dikinase （PPDK）） in different organs of ten soybean cultivars with different yields were measured at different growth stages in China. The result showed that four enzyme activities in C4 pathway were obviously different among cultivars, especially PPDK activity was not detected in the leaves of Dongnong 1567 and Dongnong 1068 and the young leaves of Gongjiao 9107-1 and Dongnong 97-172, but there were weak activities in pod coats. The order of C4 enzyme activities is young leaves 〈 old leaves 〈 pod coats. The correlation coefficients between PEPCase activity and yield and between NADP-MDH activity at blooming stage and yield were 0.6979 and 0.6565, respectively, and both reached the significant level （5%）, and PEPCase activity kept significant positive correlation with plant photosynthetic rate. There was a negative correlation between NADP-ME activity and yield, and no correlation was found between PPDK activity and yield.

为探寻棕榈藤材具有优良韧性的机理和棕榈藤材高值化利用,选择高地钩叶藤为研究对象,利用显微共聚焦拉曼技术,对导管壁化学成分的微区分布进行测试分析。结果表明,高地钩叶藤导管壁纤维素分子浓度为次生壁>复合胞间层>细胞角隅,而木质素分子浓度分布恰好相反。次生壁内、外层纤维素、木质素及半纤维素分子浓度差异较小。在藤茎径向上,藤芯处导管次生壁中层和细胞角隅处木质素的分子浓度最高,藤皮处导管的半纤维素分子浓度最高。藤皮处导管次生壁中层纤维素的分子浓度最低而细胞角隅处却最高,而藤中与藤芯处导管细胞角隅中半纤维的分子浓度均很小。在藤茎轴向上,随着高度增加藤皮导管次生壁中层木质素和半纤维素分子浓度变化趋势相同,而纤维素分子浓度在藤皮与藤芯间变化趋势完全相反。除导管各壁层的三大素分布呈一定规律性外,在藤茎径向和轴向上规律不明显。

Polyester and polyether are two key oxygenated polymers, and completely alternative sequence of poly(ester-alt-ether) could efficiently combine the advantages(including flexibility, degradability, etc.) of both segments. Currently, despite their copolymers could be synthesized from one-pot mixture of cyclic esters and epoxides, perfectly alternative microstructure is very challenging to realize and typically restricted to certain monomer pairs. Moving forward, synthesizing poly(ester-alt-ether) from commercially available and largescale monomers would be a significant advance. For example, successfully commercialized poly(glycolic acid)(PGA), which is not easily soluble in polymers due to its high crystallinity and is brittle and difficult to control the degradation cycle, would encounter a new paradigm if engineered into poly(ester-altether). In this work, starting from the design of monomer with hybrid structures, we successfully synthesized a series of 1,4-dioxan-2-one containing different substituents based on glycolide(GA) and epoxides using commercially available Salen-Cr(III) and PPNCl catalytic *** new monomers underwent ring-opening polymerization(ROP) to form a series of poly(ester-alt-ether) with perfectly alternating glycolic acid and propylene glycol repeat units under catalytic system of thiourea/base. The poly(ester-alt-ether) have significantly lower glass-transition temperature than PGA. Additionally, the poly(ester-alt-ether) can be chemically recovered to monomer using Sn(Oct)2 or 1,8-diazabicyclo[5.4.0]undecane-7-ene(DBU) as a catalyst in solution, thus establishing a closed-loop life cycle. From monomers derived from GA and epoxides, this work furnishes a novel strategy for the synthesis of poly(ester-alt-ether) with chemical recyclability.
