Associations between inorganic arsenic in rice and groundwater arsenic in the Mekong Delta

Rizlan Bernier-Latmani, Matthew Charles Reid

There is growing concern regarding human dietary exposure to arsenic (As) via consumption of rice. The concentration and speciation of As in rice are highly variable, and models describing rice As speciation as a function of environmental covariates remain ...

Variability in arsenic methylation efficiency across aerobic and anaerobic microorganisms

Rizlan Bernier-Latmani, Karin Lederballe Meibom, Karen Elda Viacava Romo, Arnaud Michel Gelb, Leia Soraya Véronique Falquet, Shannon Eliot Dyer, Adrien Mestrot

Microbially-mediated methylation of arsenic (As) plays an important role in the As biogeochemical cycle, particularly in rice paddy soils where methylated As, generated microbially, is translocated into rice grains. The presence of the arsenite (As(III)) m ...

Methylation of arsenic by single-species and soil-derived microbial cultures

Karen Elda Viacava Romo

Arsenic (As) is simultaneously a ubiquitous and a toxic element. Arsenic is subject to bio-transformations catalyzed by microorganisms constituting the As biogeochemical cycle. The primordial Earth was devoid of oxygen, exposing life to the highly mobile a ...

Intergranular Strain Evolution During Biaxial Loading: A Multiscale FE-FFT Approach

Helena Van Swygenhoven, Steven Van Petegem

Predicting the macroscopic and microscopic mechanical response of metals and alloys subjected to complex loading conditions necessarily requires a synergistic combination of multiscale material models and characterization techniques. This article focuses o ...

Arsenic methylation dynamics in a rice paddy soil anaerobic enrichment culture

Rizlan Bernier-Latmani, Julien Maillard, Alexandre Bagnoud, Leia Soraya Véronique Falquet, Matthew Charles Reid

Methylated arsenic (As) species represent a significant fraction of the As accumulating in rice grains, and there are geographic patterns in the abundance of methylated arsenic in rice that are not understood. The microorganisms driving As biomethylation i ...

Resequencing 50 accessions of cultivated and wild rice yields markers for identifying agronomically important genes

Lei Huang, Xun Xu, Jian Wang, Jeffrey David Jensen, Xin Liu, Jun Wang, Wen Wang, Chang Yu

Rice is a staple crop that has undergone substantial phenotypic and physiological changes during domestication. Here we resequenced the genomes of 40 cultivated accessions selected from the major groups of rice and 10 accessions of their wild progenitors ( ...

Genotypic variation in drought stress response and subsequent recovery of wheat (Triticum aestivum L.)

Constant Signarbieux

Three wheat (Triticum aestivum L.) genotypes, Sadovo, Katya and Prelom, with different tolerance to drought were comparatively evaluated in terms of leaf respiratory responses to progressing dehydration and consecutive rewatering. Under drought stress, the ...

Stratégies villageoises pour la gestion des paysages forestiers du Menabe Central, Madagascar

Clémence Dirac Ramohavelo

Introduction In order to reduce deforestation, the current attitude of conservation programmes and forest politics does no longer ban the local populations from the forests, because such measures present negative consequences for the communities. Today's t ...

Designing new materials from wheat protein

John Christopher Plummer, Ignaas Herman Johannes Verpoest

We recently discovered that wheat gluten could be formed into a tough, plasticlike substance when thiol-terminated, star-branched molecules are incorporated directly into the protein structure. This discovery offers the exciting possibility of developing b ...

Asymmetric Total Synthesis of (11r,12s,13s,9z,15z)-9,12,13-Trihydroxyoctadeca-9,15-Dienoic Acid, a Self-Defensive Agent against Rice-Blast Disease

Pierre Vogel

The Diels-Alder adduct of furan and 1-cyanovinyl (1'R)-camphanate was converted into methyl[(tert-butyl)dimethylsilyl 5-deoxy-2,3-O-isopropylidene-beta-L-ribo-hexofuranosid]uronate ((+)-4). Reduction with diisobutylaluminium hydride gave the corresponding ...
