This article provides a summary of current knowledge about wheat metabolites that may affect resistance against Fusarium head blight (FHB). The mechanisms of resistance, the roles of secondary metabolites in wheat defense, and future directions for breeding are assessed. The soluble phenols play an important role in redox regulation in plant tissues and can act as antimicrobial compounds. The color of cereal hulls and grains is caused by such natural pigments as anthocyanins in the aleurone, endosperm, and pericarp layers of the grain. Phenolic acids, alkylresorcinols, and phytohormones actively participate in the defense system, whereas carotenoids show various effects against Fusarium species that are positively correlated with the levels of their mycotoxins. Pathogen infestation of vegetative tissues induces volatile organic compounds production, which can provide defensive functions to infested wheat. The efficient use of native resistance in the wheat gene pool, introgression of resistant alleles, and implementation of modern genotypic strategies to increase levels of native secondary metabolites with antifungal properties can enhance the FHB resistance of new varieties. Expanding the breeding interest in the use of forms with different grain color and plant organs can be a potential benefit for the creation of lines with increased resistance to various stresses.

The introduction argues for recognition of specific Native American aesthetic and literary cultures prior to European arrival and highlights their ongoing influence and significance during the eighteenth and nineteenth centuries. During a period of American literary development known for white appropriation of Native American content, Native resistance to Euro-American settler colonialism involved aesthetic practices such as narrative mapping, visual art, storytelling, figurative representation, and adornment. These practices contributed to both Native and non-Native literary production, despite Euro-American authors’ assertions that sophisticated artistic traditions were a European import to the North American continent. Bringing the concepts “literary,” “aesthetic” and “representation” to bear on analysis of cross-cultural encounter, the introduction posits new modes of understanding points of connection or distance between Native and non-Native aesthetic practice.

This chapter opens with detailed analysis of deculturation policy during the Spanish, Mexican, and American governance of New Mexico and the Pueblos. In the more recent history it includes discussion of the Code of Indian Offenses, the General Allotment Act (Dawes Act), the Carlisle Indian School, the Canton Asylum for Insane Indians (Hiawatha Asylum), and the evolving policies of the Archdiocese of Santa Fe. These introductory remarks are followed by analyses of a 1935–1940 conflict at Santo Domingo (Kewa) Pueblo, when Archbishop Rudolph Gerken attempted to change traditional practice of Catholicism and to house a resident priest and sisters at Santo Domingo; and of a conflict at Isleta Pueblo that culminated when Monsignor Frederick Stadtmueller was removed in handcuffs by the pueblo governor in 1965. The Native American ministry of the archdiocese and native resistance to dogma are also considered more generally. Visiting information for Kewa and Isleta is included.

The native populations of Portuguese America were essential for the implementation of the Portuguese colonial project. Their labor was indispensable in constructing the colony, and political alliances with native peoples ensured the success of the conquest at several crucial moments, and only with the aid of native knowledge it was possible to occupy the land and advance the conquest of the immense territory that became known as Brazil. In this sense, peace was a necessity. Yet, in highlighting the centrality of Indians in the settlement of the Portuguese colony in the Americas, it must also be recognized that the relations established there between Portuguese conquerors and native populations were also historically marked by tension and violence. A war of extermination, often masquerading as a “just war,” and slavery became inseparable parts of colonial strategy. Moreover, access to land and the use of indigenous labor could both constitute secure indicators of success in the conquest of Portuguese America. In the process of colonization the Portuguese Crown was confronted by various forms of native resistance and by the differing interests of diverse colonial agents. During the 17th and 18th centuries the Crown faced tensions, disputes, and contradictions in relation to the slavery and freedom of Indians and the way it solved these conflicts revealed the configuration of its indigenist policy.
