Verticillium dahliae causes significant losses in cotton production. To reveal the mechanism of the defense response to V. dahliae in cotton, transcriptomic analyses were performed using cotton cultivars M138(V. dahliae-resistant)and P2(V. dahliae-susceptible). The results revealed 11,076 and 6,640 differentially expressed genes(DEGs)in response to V. dahliae, respectively. The weighted gene co-expression network analysis of 4,633 transcription factors(TFs) indicated a “MEblue” module containing 654 TFs that strongly correlate with resistance to V. *** these TFs, the ethylene response factor Ghi＿A05G10166(GhERF91) was identified as a putative hub gene with a defense response against V. dahliae. A virus-induced gene silencing assay and exogenous application of ethephon showed that GhERF91 is activated by ethylene and positively regulates the response to V. dahliae exposure in cotton. This study provides fundamental transcriptome data and a putative causal gene(GhERF91)associated with resistance to V. dahliae, as well as genetic resources for breeding V. dahliae-resistant cotton.

Mitigation of ELMs by electrostatic field is studied. The perpendicular heating in cyclotron waves tends to pile up the resonant particles toward the low magnetic field side in which a electrostatic field may result [J. Y. Hsu, V. S. Chan, R. W. Harvey, R. Prater, and S. K. Wong, Phys. Rev. Lett. 53, 564 (1984)]. The electrostatic field can make circulating particles trapped or make trapped particles circulating depending on the field direction. The trapped- particle population and bootstrap current change accordantly. Modulating bootstrap current, mitigation of type-1 ELM by the electrostatic field is possible. The electrostatic potential needed for the mitigation is quantitatively estimated. Experiments by either ECRH or biasing are being prepared to verify the theory.

一种新型仿龟的柔性微型机器人,具有四条腿并能在水下爬行和游动,其中龟腿由一种智能薄膜ICPF(Ionic Conducting Ploymer Fil m)驱动。ICPF具有被低电压驱动、柔性和快速响应的特点。为了提高机器龟的可靠性和灵活性,我们运用伪刚体动力学法(PRBDM)建立了机器龟腿的动力学模型,此模型是基于静力学和运动学并考虑了动态影响因素建立起来的。然后,分析了机器龟腿的角位移幅度系数的变化规律。最后通过实验测量了机器龟腿末端的位移,其变化规律与理论上推导出的结果相近,因此验证了龟腿的动力学模型可以比较精确地反映龟腿的摆动角度位移,可以分析龟腿的频率特性。

金融交易指标是分析股票等金融产品买入和卖出策略的普遍选择,但由于指标描述交易策略的模糊性,使得非专业人士很难掌握交易的时间和数量。针对上述问题,本文首先分析随机指标的交易策略。其次根据交易策略和模糊集理论建立模糊推理系统模型,此模型可以给出具体的股票交易策略,包括买入以及卖出的时间和数量等,并通过给定时间段内的获利情况来判断模型的有效性。最后以沪深A股市场的15只股票价格作为实验数据,对模型的有效性进行检验。实验表明,在没有人为因素参与的情况下,大多数股票由系统进行模拟交易都可以在一段时间内获取更大的利润。

AIM: To further analyse cancer involvement of basic transcription factor 3 (BTF3) after detection of its upregulation in gastric tumor samples. METHODS: BTF3 transcription rates in human gastric tumor tissue samples (n = 20) and adjacent normal tissue (n = 18) specimens as well as in the gastric cancer cell lines AGS, SGC-7901, MKN-28, MKN-45 and MGC803 were analyzed via quantitative real-time polymerase chain reaction. The effect of stable BTF3 silencing via infection with a small interfering RNA (siRNA)-BTF3 expressing lentivirus on SGC-7901 cells was measured via Western blotting analysis, proliferation assays, cell cycle and apoptosis profiling by flow cytometry as well as colony forming assays with a Cellomic Assay System. RESULTS: A significant higher expression of BTF3 mRNA was detected in tumors compared to normal gastric tissues (P lines expressed high levels of BTF3. From days 1 to 5, the relative proliferation rates of stable BTF3-siRNA transfected SGC7901 cells were 82%, 70%, 57%, 49% and 44% compared to the control, while the percentage of cells arrested in the G 1 phase was significantly decreased (P = 0.000) and the percentages of cells in the S (P = 0.031) and G 2 /M (P = 0.027) phases were significantly increased. In addition, the colony forming tendency was significantly decreased (P = 0.014) and the apoptosis rate increased from 5.73% to 8.59% (P = 0.014) after BTF3 was silenced in SGC7901 cells. CONCLUSION: BTF3 expression is associated with enhanced cell proliferation, reduced cell cycle regulation and apoptosis and its silencing decreased colony forming and proliferation of gastric cancer cells.

在UV-B辐射下,培养群体和单细胞的铜绿微囊藻,研究了外源的SNP(硝普钠,NO供体)、AsA(抗坏血酸)对铜绿微囊藻可溶性蛋白质含量、抗氧化保护酶活性的影响.实验结果表明:随着UV-B辐射的增强,群体和单细胞微囊藻的可溶性蛋白质含量先上升后下降,POD(过氧化物酶)、SOD(超氧化物歧化酶)活性也呈现先上升后下降趋势.在经过2 h照射后,抗氧化酶的活性都大于对照所发生的变化,而群体的抗氧化酶始终保持着比单细胞更高的活性,这说明群体比单细胞更能耐受UV-B胁迫.同时SNP处理组所测得的数据均比对照组和AsA处理组大,这说明SNP能更好地协助铜绿微囊藻耐受UV-B辐射.
