qPCR (quantitative polymerase chain reaction) and random amplified polymorphic DNA (RAPD) were utilized to investigate genetic stability of Palmer amaranth cloned plants over 10 generations. DNA from original parent Palmer amaranth plants (grown from seeds) was re-analyzed using qPCR, and confidence levels for determining ΔΔCt (threshold crossing) values were established. ANOVA was used to determine variation (margin of error) of these ΔΔCt values. This margin of error was applied to qPCR analysis of DNA from eight individual parent plants and their descendants (10th generation) so that possible differences in EPSPS (5-enolpyruvylshikimate-3-phosphate synthase) gene copy number could be ascertained. This method (and the associated error) indicated a lack of agreement in ΔΔCt values of DNA from plants of these two generations. qPCR analysis showed that in five out of eight clones, EPSPS gene copy number varied more than the calculated error (P = 0.05). A second technique to monitor genetic stability, RAPD was used to determine possible changes in genomic DNA due to extended cloning of these regenerated plants. RAPD analysis showed that four out of the eight clones differed when the profiles of the two generations were compared. Results show that qPCR and RAPD analysis point to the fact that several Palmer amaranth clones experienced changes in genome structure over 10 generations. Although the glyphosate resistance trait was retained, results suggest that during cloning studies, the genetic stability of macro-vegetatively propagated lines should be monitored.

本文以iPhone为例,来阐明即使那些由美国公司发明的高科技产品,也可能不会增加美国出口,反而会扩大美国贸易逆差。2009年中美iPhone贸易逆差约为19亿美元。空前的全球化、组织良好的全球生产网络、迅速发展的国际分工以及廉价的运输成本,都可能影响跨国公司如Apple公司的经营决策,而这些经营决策可能直接恶化美国的贸易逆差。全球生产网络与高度专业化的生产过程,明显改变了贸易形态:像中国这样的发展中国家现在出口iPhone这样的高科技产品,而像美国这样的工业化国家则进口原本由自己发明的高科技产品。此外,传统贸易统计方法无法识别制造业产品价值的跨国分配,极度夸大了被跨国公司作为出口平台的国家与目标市场国家之间的双边贸易失衡。

To study the genetic association and epistatic interaction of the interleukin (IL)-10 and IL-10/STAT3 pathways in pediatric inflammatory bowel disease (IBD). METHODSA total of 159 pediatric inflammatory IBD patients (Crohn’s disease, n = 136; ulcerative colitis, n = 23) and 129 matched controls were studied for genetic association of selected single nucleotide polymorphisms (SNPs) of the IL-10 gene and the genes IL10RA, IL10RB, STAT3, and HO1, from the IL-10/STAT3 signaling pathway. As interactions between SNPs from different loci may significantly affect the associated risk for disease, additive (a) and dominant (d) modeling of SNP interactions was also performed to examine high-order epistasis between combinations of the individual SNPs. RESULTSThe results showed that IL-10 rs304496 was associated with pediatric IBD (P = 0.022), but no association was found for two other IL-10 SNPs, rs1800872 and rs2034498, or for SNPs in genes IL10RA, IL10RB, STAT3, and HO1. However, analysis of epistatic interaction among these genes showed significant interactions: (1) between two IL-10 SNPs rs1800872 and rs3024496 (additive-additive P = 0.00015, Bonferroni P value (Bp) = 0.003); (2) between IL-10RB rs2834167 and HO1 rs2071746 (dominant-additive, P = 0.0018, Bp = 0.039); and (3) among IL-10 rs1800872, IL10RB rs2834167, and HO1 rs2071746 (additive-dominant-additive, P = 0.00015, Bp = 0.005), as well as weak interactions among IL-10 rs1800872, IL-10 rs3024496, and IL-10RA (additive-additive-additive, P = 0.003; Bp = 0.099), and among IL10RA, IL10RB, and HO1 genes (additive-dominant-additive, P = 0.008, Bp = 0.287). CONCLUSIONThese results indicate that both the IL-10 gene itself, and through epistatic interaction with genes within the IL-10/STAT3 signaling pathway, contribute to the risk of pediatric IBD.

Abstract： The objective of this study was to provide insights on the motivations behind the decision of biodynamic producers in the United States to shift to biodynamic practices in the vineyard and winemaking process. The second objective of the study was to evaluate the perceptions of the consumers regarding eco-label wines, with a direct focus on the attitudes of millennial generation. Two surveys, one directed to biodynamic producers in the United States and the other to a group of Californian wine consumers were distributed during spring and fall of 2010. Findings from the first survey reveal that biodynamic producers are engaged in biodynamic practices out of socially motivated reasons rather than economic factors. Results from the consumer survey suggest a generally uninformed generation of consumers about eco-label wines and particularly about the practices associated with these products. This lack of information heavily influences their behavioral decisions and attitudes and points out to the critical need for consumer education.
