Biocoloniality, governance, and the protection of ‘genetic identities’ in Mexico and Colombia

In this article two case studies are compared, Mexico and Colombia, in which the protection of ‘genetic identities’ has generated political and legal systems designed to avoid the unlawful appropriation of biological material and/or DNA in Latin America. The very idea that genetic patrimonies belong to nation-states or ethno-racial groups – framed as genomic sovereignty or the protection of a disappearing indigenous genetic heritage – is the product of a genetically reified understanding of human diversity, which we identify as ‘biocoloniality’. By exploring the common tropes and imaginations with which biocoloniality has been articulated, we argue that governance mechanisms built around ‘genetic identities’ are ineffective in addressing the unequal power relations inherent in contemporary scientific and regulatory practice

Explaining the visible and the invisible: Public knowledge of genetics, ancestry, physical appearance and race in Colombia

This is the final version of the article. Available from SAGE Publications via the DOI in this record.Using data from focus groups conducted in Colombia, we explore how educated lay audiences faced with scenarios about ancestry and genetics draw on widespread and dominant notions of nation, race and belonging in Colombia to ascribe ancestry to collectivities and to themselves as individuals. People from a life sciences background tend to deploy idioms of race and genetics more readily than people from a humanities and race-critical background. When they considered individuals, people tempered or domesticated the more mechanistic explanations about racialized physical appearance, ancestry and genetics that were apparent at the collective level. Ideas of the latency and manifestation of invisible traits were an aspect of this domestication. People ceded ultimate authority to genetic science, but deployed it to work alongside what they already knew. Notions of genetic essentialism co-exist with the strategic use of genetic ancestry in ways that both fix and unfix race. Our data indicate the importance of attending to the different epistemological stances through which people define authoritative knowledge and to the importance of distinguishing the scale of resolution at which the question of diversity is being posed.This article arises out of two projects: ‘Race, genomics and mestizaje (mixture) in Latin America: a comparative approach’ funded by the Economic and Social Research Council (ESRC) (grant RES-062-23-1914) and ‘Public engagement with genomic research and race in Latin America’ funded by The Leverhulme Trust (grant RPG-044)

“The Map of the Mexican’s Genome”: overlapping national identity, and population genomics

This is the final version of the article. Available from Springer Verlag via the DOI in this record.This paper explores the intersections between national identity and the production of medical/population genomics in Mexico. The ongoing efforts to construct a Haplotype Map of Mexican genetic diversity offers a unique opportunity to illustrate and analyze the exchange between the historic-political narratives of nationalism, and the material culture of genomic science. Haplotypes are central actants in the search for medically significant SNP’s (single nucleotide polymorphisms), as well as powerful entities involved in the delimitation of ancestry, temporality and variability (www.hapmap.org). By following the circulation of Haplotypes, light is shed on the alignments and discordances between socio-historical and bio-molecular mappings. The analysis is centred on the comparison between the genomic construction of time and ethnicity in the laboratory (through participant observation), and on the public mobilisation of a “Mexican Genome” and its wider political implications. Even though both: the scientific practice and the public discourse on medical/population genomics are traversed by notions of “admixture”, there are important distinctions to be made. In the public realm, the nationalist post-revolutionary ideas of Jose Vasconcelos, as expressed in his Cosmic Race (1925), still hold sway in the social imaginary. In contrast, admixture is treated as a complex, relative and probabilistic notion in laboratory practices. I argue that the relation between medical/population genomics and national identity is better understood as a process of re-articulation (Fullwiley Social Studies of Science 38:695, 2008), rather than coproduction (Reardon 2005) of social and natural orders. The evolving process of re-articulation conceals the novelty of medical/population genomics, aligning scientific facts in order to fit the temporal and ethnic grids of “Mestizaje”. But it is precisely the social and political work, that matches the emerging field of population genomics to the pre-existing projects of national identity, what is most revealing in order to understand the multiple and even subtle ways in which population genomics challenges the historical and identitarian frames of a “Mestizo” nation.The Mexican Council of Science and Technology (CONACYT), has been generous to fund the studies and research interests of both of u

Building the genomic nation: ‘Homo Brasilis’ and the ‘Genoma Mexicano’ in comparative cultural perspective

This is the final version of the article. Available from SAGE Publications via the DOI in this record.This article explores the relationship between genetic research, nationalism and the construction of collective social identities in Latin America. It makes a comparative analysis of two research projects – the ‘Genoma Mexicano’ and the ‘Homo Brasilis’ – both of which sought to establish national and genetic profiles. Both have reproduced and strengthened the idea of their respective nations of focus, incorporating biological elements into debates on social identities. Also, both have placed the unifying figure of the mestizo/mestiço at the heart of national identity constructions, and in so doing have displaced alternative identity categories, such as those based on race. However, having been developed in different national contexts, these projects have had distinct scientific and social trajectories: in Mexico, the genomic mestizo is mobilized mainly in relation to health, while in Brazil the key arena is that of race. We show the importance of the nation as a frame for mobilizing genetic data in public policy debates, and demonstrate how race comes in and out of focus in different Latin American national contexts of genomic research, while never completely disappearing.This article arises out of two projects: ‘Race, genomics and mestizaje (mixture) in Latin America: a comparative approach’ funded by the ESRC (grant RES-062-23-1914) and ‘Public engagement with genomic research and race in Latin America’ funded by The Leverhulme Trust (grant RPG-044)

Diversification and Specialization of Plant RBR Ubiquitin Ligases

Background: RBR ubiquitin ligases are components of the ubiquitin-proteasome system present in all eukaryotes. They are characterized by having the RBR (RING – IBR – RING) supradomain. In this study, the patterns of emergence of RBR genes in plants are described. Methodology/Principal Findings: Phylogenetic and structural data confirm that just four RBR subfamilies (Ariadne, ARA54, Plant I/Helicase and Plant II) exist in viridiplantae. All of them originated before the split that separated green algae from the rest of plants. Multiple genes of two of these subfamilies (Ariadne and Plant II) appeared in early plant evolution. It is deduced that the common ancestor of all plants contained at least five RBR genes and the available data suggest that this number has been increasing slowly along streptophyta evolution, although losses, especially of Helicase RBR genes, have also occurred in several lineages. Some higher plants (e. g. Arabidopsis thaliana, Oryza sativa) contain a very large number of RBR genes and many of them were recently generated by tandem duplications. Microarray data indicate that most of these new genes have low-level and sometimes specific expression patterns. On the contrary, and as occurs in animals, a small set of older genes are broadly expressed at higher levels. Conclusions/Significance: The available data suggests that the dynamics of appearance and conservation of RBR genes is quite different in plants from what has been described in animals. In animals, an abrupt emergence of many structurall

Customer values and CSR image in the banking industry.

ABSTRACT: The authors analyse the role that collectivism and novelty seeking play in the formation process of corporate social responsibility (CSR) image in the Spanish banking industry. Two multisampling analyses of a structural equation model are performed on a sample of 1124 customers. The findings of the article allow the authors to anticipate CSR image based on (i) the congruence between the company and its CSR initiatives, (ii) the attribution of motivations for the company to implement CSR and (iii) corporate credibility in developing CSR initiatives. The findings also show that collectivists and innovative customers process information differently to individualists and conservative customers

High mutation rates explain low population genetic divergence at copy-number-variable loci in Homo sapiens

Copy-number-variable (CNV) loci differ from single nucleotide polymorphic (SNP) sites in size, mutation rate, and mechanisms of maintenance in natural populations. It is therefore hypothesized that population genetic divergence at CNV loci will differ from that found at SNP sites. Here, we test this hypothesis by analysing 856 CNV loci from the genomes of 1184 healthy individuals from 11 HapMap populations with a wide range of ancestry. The results show that population genetic divergence at the CNV loci is generally more than three times lower than at genome-wide SNP sites. Populations generally exhibit very small genetic divergence (G(st) = 0.05 ± 0.049). The smallest divergence is among African populations (G(st) = 0.0081 ± 0.0025), with increased divergence among non-African populations (G(st) = 0.0217 ± 0.0109) and then among African and non-African populations (G(st) = 0.0324 ± 0.0064). Genetic diversity is high in African populations (~0.13), low in Asian populations (~0.11), and intermediate in the remaining 11 populations. Few significant linkage disequilibria (LDs) occur between the genome-wide CNV loci. Patterns of gametic and zygotic LDs indicate the absence of epistasis among CNV loci. Mutation rate is about twice as large as the migration rate in the non-African populations, suggesting that the high mutation rates play dominant roles in producing the low population genetic divergence at CNV loci
