  • easyGWAS: A Cloud-based Platform for Comparing the Results of Genome-wide Association Studies

    Abstract The ever-growing availability of high quality genotypes for a multitude of species has enabled researchers to explore the underlying genetic architecture of complex phenotypes at an unprecedented level of detail using genome-wide association studies (GWAS). The systematic comparison of results obtained from GWAS of different traits opens up new possibilities, including the analysis ...

  • Field of genes: Uncovering EGRINs (Environmental Gene Regulatory Influence Networks) in Rice that Function During High-temperature and Drought Stress

    Heat and drought stress greatly restrict crop productivity, but most of what we know about a plant’s response to these stresses comes from controlled laboratory studies. This factor, along with the complex nature of these responses, has hampered efforts to breed and engineer crops with improved stress tolerance. Plants respond to fluctuating environments through the altered expression of ...

  • A call to conserve crops’ wild cousins

    Wild cousins aren’t always appreciated at family gatherings. But when it comes to crops, the opposite is often true: Plant breeding has historically relied on genes from plants growing in the wild as a source of diversity that can be introduced into crop plants to produce new crop varieties that are more resilient, nutritious and productive than those currently cultivated. As human ...

  • Species traits and shoot-root biomass allocation in 20 dry-grassland species

    Abstract Aims: A plant has a limited amount of resources at any time and it allocates them to different structures. In spite of the large number of previous studies on allocation patterns within single species, knowledge of general patterns in species allocation is still very limited. This is because each study was done in different conditions using different methodology, ...

  • Altitudinal patterns of maximum plant height on the Tibetan Plateau

    Abstract Aims Several studies have shown that plant height changes along environmental gradients. However, altitudinal patterns of plant height across species are still unclear, especially in regions sensitive to climate change. As canopy height decreases dramatically near the tree line in alpine areas, we hypothesize that plant height across all species also decreases with ...

  • The adaptive value of grass traits in response to grazing

    Abstract Aims Grazing is associated with several plant traits that may confer resistance to herbivores. However, cross species analyses do not allow for the differentiation between adaptive evolution and common ancestry. In this study, we evaluated the effect of grazing on five morphological traits in 41 native grasses growing in natural grasslands of Uruguay and ...

  • Can genetic engineering help quench crops’ thirst?

    Researchers around the world are exploring how GMO technology might boost food production under hot, dry conditions. Roger Deal is trying to figure out how plants remember drought. An assistant professor of biochemistry and genetics at Emory University, Deal says most plants have a kind of memory for stress. When experiencing water shortage, for example, plants close ...

  • DOE accepting nominations for biomass research and development technical advisory committee

    On July 15, 2015, DOE posted a solicitation notice for candidates for the Biomass Research and Development Technical Advisory Committee. According to the notice, DOE is specifically looking for candidates with experience in biobased industrial/commercial products, non-federal government engineers or scientists, academia with expertise in ...

  • Crop gene banks are preserving the future of agriculture. But who’s preserving them?

    As climate change makes crop diversity even more important, gene banks struggle to stay afloat. During the past few years of civil war in Syria, rebel fighters have destroyed Shia mosques and Christian graves, and burned and looted Christian churches while the Islamic State group has demolished priceless artifacts in the region. Nothing seemed sacred to the disparate ...

  • Better photosynthesis for a better world?

    There’s no question that plants are better than most other life forms at converting carbon dioxide and sunlight into the sugars that form the basis of our global food web — and eventually, humans’ entire food supply. But fact of the matter is, with conversion rates hovering around 2 percent for our best crop fields, they’re by no means great. Even a slight increase in the ...

  • Indian government still ‘flip flopping’ on GM trials

    In August, India’s ruling nationalist Bharatiya Janata Party (BJP) stopped its legislators from accepting Monsanto sponsorship to attend a farm exhibition in the US state of Iowa. On the surface this might seem strange: attending the Farm Progress Show should be innocuous, as Monsanto routinely takes farmers, industry experts, media and MPs from various countries to visit the show and ...

  • The problems with the arguments against GM crops

    New evidence shows that arguments against GM crops are unfounded, says Margaret Karembu. The year 2013 marked the 18th consecutive year of commercial cultivation of genetically modified organisms (GMOs) or now commonly referred to as biotech crops. And in just under two decades, the volume of ...

  • Toxicity of biosolids‐derived triclosan and triclocarban to six crop species

    Biosolids are an important source of nutrients and organic matter, which are necessary for the productive cultivation of crop plants. Biosolids have been found to contain the personal care products, triclosan and triclocarban, at high concentrations relative to other pharmaceuticals and personal care products. The current study investigates whether exposure of six plant species (radish, ...

  • The socio–economic impacts of currently commercialised genetically engineered crops

    A substantial and growing body of literature now exists on the socio–economic impacts of genetically engineered (GE) crops. While the bulk of literature has focused on the primary impacts of commercialised GE technology, in terms of changes in yields, costs and profitability, researchers have increasingly addressed a range of additional questions such as the distribution of impacts across groups, ...

  • Accumulation and translocation of 198Hg in four crop species

    The uptake and transport of mercury (Hg) through vegetation play an important role in the biogeochemical cycling of Hg. However, quantitative information regarding Hg translocation in plants is poorly understood. In this study, Hg uptake, accumulation and translocation in four corps rice (Oryza.sativa L.), wheat (Triticum L.), corn (Zea mays L.) and oilseed rape (Brassica campestris L.) grown ...

  • Intellectual property and Freedom To Operate in the flax breeding world: Canada in the global context

    Through one-on-one in-depth interviews of Canadian public sector flax breeders, this study explores issues around Intellectual Property (IP) and Freedom To Operate (FTP) in flax breeding from a Canadian perspective. The results are supported by a scan of flax breeding efforts worldwide, an in-depth patent analysis (using Patent Lens and the US Patent and Trademark Office (USPTO) databases) and a ...

  • Prediction of daily crop reference evapotranspiration (ET0) values through a least-squares support vector machine model

    Real-time prediction of daily reference crop evapotranspiration (ET0) is the basis for estimating crop evapotranspiration and for computing crop irrigation requirements. In recent years, least-squares support vector machines (LSSVMs) have been applied for forecasting in many fields of engineering. In this paper, LSSVMs are applied to forecast ET0 using public weather forecasting data (minimum and ...

  • Breeding maize for a bioeconomy: a literature survey examining harvest index and stover yield and their relationship to grain yield

    The use of maize (Zea mays L.) stover as a feedstock for cellulosic biofuels production will create demand for maize hybrids with greater stover yield. It is expected that grain yield will remain the most critical trait and continue to drive hybrid sales, requiring that any increases in stover yield be made without sacrificing grain yield potential. The objective of this review was to determine ...
