Fusarium graminearum is an economically important pathogen that causes Fusarium head blight of wheat, barley, and oat, and Gibberella ear and stalk rot of maize. More recently, F. graminearum was reported as a soybean seedling and root pathogen in North America (1,5), causing seed decay, damping-off, and brown to reddish-brown root rot symptoms. Type B trichothecene mycotoxins are commonly produced by F. graminearum, which can be categorized into three trichothecene genotypes; those that produce 3-acetyldeoxynivalenol (3-ADON), 15-acetyldeoxynivalenol (15-ADON), or nivalenol (NIV). The 15-ADON genotype is dominant in populations from small grains and maize in North America (4), but the 3-ADON genotype has recently been found (4). F. graminearum was known as a pathogen of wheat and maize in North America for over a century before it was reported as a soybean pathogen. Therefore, we hypothesized that recent reports on soybean could be associated with the appearance of the 3-ADON genotype. The objective of this research was to determine the trichothecene genotype of F. graminearum isolates from soybean in the United States. Thirty-eight isolates from soybean were evaluated. Twenty-seven isolates came from a 3-year survey for Fusarium root rot from 2007 to 2009 in Iowa. Other isolates (Ahmad Fakhoury, Southern Illinois University, Carbondale) were collected from soybean seedlings during a multi-state survey in 2012, and included three isolates from Illinois, three from Indiana, and five from Nebraska. Species identification and lineage of F. graminearum were confirmed by sequencing the translation elongation factor gene (EF1-α) using EF-1H and EF-2T primers. A maximum likelihood analysis of the EF1-α, including voucher strains from nine lineages of F. graminearum (2), placed all 38 isolates into lineage 7, F. graminearum sensu stricto (representative GenBank accessions KJ415349 to KJ415352). To determine the trichothecene genotype of each isolate we used three multiplex PCR assays. The first two assays targeted a portion of trichothecene biosynthesis genes Tri3 and Tri12 (4), while the third assay targeted portions of the Tri3, Tri5, and Tri7 genes (3). The PCR for the first two assays was conducted as described by Ward et al. (4) using four sets of primers: 3CON, 3NA, 3D15A, and 3D3A; and 12CON, 12NF, 12-15F, and 12-3F for the Tri3 and Tri12 genes, respectively. The PCR for the third assay was conducted as described by Quarta et al. (3) using the following primers: Tri3F971, Tri3F1325, Tri3R1679, Tri7F340, Tri7R965, 3551H, and 4056H. The amplification products were analyzed by gel electrophoresis. All 38 isolates produced amplicons consistent with the 15-ADON genotype; ~610 and 670 bp for the Tri3 and Tri12 genes, respectively (4), and two amplicons of ~708 and 525 bp for the Tri3/Tri5 genes (3). Our results indicated that the dominant trichothecene genotype among isolates of F. graminearum from soybean is 15-ADON, and the introduction of 3-ADON isolates does not explain the recent host shift of F. graminearum to soybean in North America. To our knowledge, this is the first assessment of trichothecene genotypes in F. graminearum populations from soybean from the United States. References: (1) K. E. Broders et al.

This introductory chapter discusses the important role of hunger during the American Revolution. Enduring, ignoring, creating, and preventing hunger were all ways to exercise power during the American Revolution. Hunger prompted violence and forged ties; it was a weapon of war and a tool of diplomacy. In North America, Cherokee, Creek, Delaware, Iroquois (Haudenosaunee), Miami, and Shawnee Indians grew and destroyed foodstuffs during the Revolutionary War, which forced their British and American allies to hunger with them, and to furnish provisions that accommodated Native tastes. By the 1810s, the United States had learned how to prevent Indian hunger, to weaponize food aid, and to deny Indians the power gained by enduring and ignoring scarcity. Meanwhile, people of African descent gained some power by creating white hunger during the Revolutionary War, but more so as formerly enslaved communities, primarily after leaving the new United States and migrating to British colonies in Nova Scotia and then Sierra Leone. After white officials in Sierra Leone realized that colonists' hunger-prevention efforts gave them too much freedom, black colonists lost their hunger-preventing rights. Ultimately, three key behaviors changed and were, in turn, changed by evolving ideas about hunger: food diplomacy, victual warfare, and victual imperialism.

Abstract First North American records are presented for Cryptocephalus moraei (Linnaeus, 1758) (Coleoptera: Cryptocephalinae) and Psylliodes dulcamarae (Koch, 1803) (Coleoptera: Galerucinae: Alticini), as confirmed by morphology and DNA barcoding. Additional information is presented about phenology and host use for C. moraei, the first European Cryptocephalinae to be found elsewhere as conclusively adventive. Cryptocephalus moraei is expected to have no ecological impact on its host, the adventive Hypericum perforatum Linnaeus (Hypericaceae). However, P. dulcamarae, the second recently discovered flea beetle associated with the adventive Solanum dulcamara Linnaeus (Solanaceae), probably does harm that host. Both species are hypothesised to have arrived from Europe with woody plant material imported with soil during 1960–1965. A literature review of introduced Chrysomelidae found that Canada and the United States of America are together home to 68–78 species of adventive Chrysomelidae. All non-Bruchinae species among these are both native to Europe and occur either in Canada or both Canada and United States of America, except for intentionally introduced biological control agents and two species that feed on Eucalyptus L’Héritier de Brutelle (Myrtaceae). This suggests a dominant role of accidental introductions of cool-climate European species in recent unplanned additions to the fauna of leaf-feeding Chrysomelidae in North America.

The third and final article of the three-part series of articles «Artificial intelligence in the economy and politics of our time» (the first and second articles of the series were published in the fourth and fifth issues of the journal for this year, respectively) presents the results of a study of the goals, motivations and specifics of the adoption of national strategies to support the development of artificial intelligence in different countries. It is shown that such a strategy in Russia is based on the idea of the most important role of using artificial intelligence in solving the most complex economic, social, and military-political problems of the country. Differences in conceptual approaches to the development of research and practical use of artificial intelligence developments in the national strategies of the largest countries of the world — the United States, China and India.

History Of

This introductory chapter serves as a foreword for the volume. It sketches the history of past restatements and the evolution of the latest one. The first (confusingly called Second) Restatement of the Foreign Relations Law of the United States brought widespread attention to the term “foreign relations law.” It staunchly defended the proposition that foreign relations, no matter how imbued with discretion and prerogative, still must rest on law. The Third Restatement, prepared during a period of what to many seemed constitutional retrenchment and a loosening of judicial supervision over public life, offered a robust defense of the proposition that, “In conducting the foreign relations of the United States, Presidents, members of Congress, and public officials are not at large in a political process; they are under law.” Moreover, it insisted that the judiciary, as much as the executive and Congress, creates and enforces this law. To the extent that the Third Restatement rested its claims on its view of the state of customary international law, other influential actors pushed back. The Fourth Restatement revisits the Third’s claims, especially about the central role of the judiciary, in light of the evolution of both U.S. and international law and practice.

✓ In discussing the role of the United States in world politics, President Jimmy Carter described the changes in Europe as it prepares for unification into one economic bloc; the deteriorating conditions in the third world; the impact of the recent changes in communist countries; and the persistence of regional wars and civil disputes. He summarized the policies and activities of The Carter Center in Atlanta, Georgia. This nonprofit organization receives no government funds and can act as an independent agent in areas such as disease eradication and promotion of food production in the third world countries, and can intercede on behalf of peace in countries with civil unrest. He urged the members of the Association, as leaders of society, to use their influence in alleviating worldwide suffering.

This article examines trends in Modern Orthodoxy in North America in the 1940s. Canadian and American Orthodox rabbis and laypeople belonged to the same organizations, such as the Union of Orthodox Jewish Congregations of America and the Rabbinic Council of America (RCA). The major Orthodox rabbinic seminaries were located in the United States, and many Canadian rabbis were trained there. One of the issues the article addresses is Modern Orthodoxy’s issues with Traditional Orthodoxy, which - while newer on the scene in the 1940s - was beginning to make its mark. Orthodox leaders also took an active role in the war effort; the role of Orthodoxy was enhanced on the American scene by the contributions that the RCA made in the area of military chaplaincy. Orthodox leaders also took on a major role in the attempt to rescue European Jewry. Finally, just as there was a new role for America in Modern Orthodoxy, there was a new role for Zionism and Eretz Yisrael.
