  • Global

    Scientists Identify Plant Enzyme that can Boost Production of Biomass Feedstocks

    Scientists from the James Hutton Institute and the University of Dundee in Scotland;

    Flanders Institute for Biotechnology (VIB) and Ghent University in Belgium; and the

    University of Wisconsin in USA have identified a new enzyme caffeoyl shikimate esterase

    (CSE) which has a central role in lignin biosynthesis. Knocking-out the CSE gene resulted

    in 36% less lignin per gram of stem material. Lignin is a kind of cement that embeds sugar

    molecules and thereby gives firmness to plants. Plants with a lower amount of lignin or

    with lignin that is easier to break down can be a real benefit for biofuel and bioplastics

    production.

    These new insights can now be used to screen natural populations of energy crops such as

    poplar, eucalyptus, switchgrass or other grass species for a non-functional CSE gene.

    Alternatively, the expression of CSE can be genetically engineered in energy crops.

    US and UK Scientists Work to Design Crops of the Future

    Four teams of researchers from the United States and the United Kingdom were awarded

    more than $12 million to change current farming methods by designing crops that will

    thrive without costly and polluting artificial fertilizers.

    The National Science Foundation (NSF) in the US and UK's Biotechnology and Biological

    Sciences Research Council (BBSRC) made the awards following an 'Ideas Lab' focusing

    on new approaches to deal with the challenges of nitrogen in the growing global food

    demand. By 2015, more than 190.4 million tons of nitrogen will be needed to supply the

    world's food. Farms rely on great quantities of industrially-produced, nitrogen-rich

    fertilizer to ensure crop yields, but the practice comes with trade-offs as they are costly and

    use vast amounts of fossil fuel. They also generate environmental problems, degrade soils

    and produce runoffs into rivers polluting fresh waters and coastal zones.

    "The reliance of artificial nitrogen fertilizers for food crop production and their damaging

    environmental effects are in many ways underestimated. Fortunately, there are scientists

    paying attention to how these artificial fertilizers can be replaced by abundant atmospheric

    nitrogen," said John Wingfield, NSF's assistant director for Biological Sciences.

    The four Ideas Lab projects are:

    Nitroplast: A light-driven, synthetic nitrogen-fixing organelle

    Oxygen-tolerant nitrogenase

    Engineering synthetic symbiosis between plant and bacteria to deliver nitrogen to crops

  • Designing nitrogen fixing ability in oxygenic photosynthetic cells

    Africa

    Nigeria Releases Two Extra-Early Maturing White Maize Hybrids

    Nigeria has released two extra-early maturing maize hybrids with combined

    resistance/tolerance to Striga, drought, and low soil-nitrogen.

    The maize hybrids, developed by the International Institute of Tropical Agriculture (IITA),

    were originally known as IITA Hybrid EEWH-21 and IITA Hybrid EEWH-26, now named

    Ife Maizehyb-5 and Ife Maizehyb-6. The lines were tested extensively in Nigeria in

    partnership with the Institute of Agricultural Research and Training (IAR&T) with

    suppport from the Drought Tolerant Maize for Africa (DTMA) Project. The potential yield

    of Ife Maizehyb-5 is 6.0 t/ha and Ife Maizehyb-6 yields 5.5 t/ha. Local varieties yield about

    1.5 t/ha.

    "The release of the two extra-early hybrids should contribute to a significant reduction in

    the instability of maize yields in Nigeria as well as in other countries of West and Central

    Africa," according to Baffour Badu-Apraku, IITA maize breeder and member of the team

    that developed the hybrids.

    African Scientists Trained on Novel Genotyping Tool

    The International Crops Research Institute for the Semi-Arid Tropics' (ICRISAT) office in

    Nairobi, Kenya has organized a workshop on novel genotyping tool among African

    scientists working mainly on cereal genomics. The workshop was held at the Biosciences

    Eastern and Central Africa - International Livestock Research Institute (BECA - ILRI)

    hub. It was co-organized by the Institute for Genomic Diversity at Cornell University, with

    facilitators from Cornell University and ICRISAT.The workshop drew 32 participants

    from Tanzania, Malawi, Zimbabwe, South Africa, Uganda, Kenya, Ethiopia, Sudan,

    Eritrea, Niger and Zambia, representing both CGIAR centers and national programs.

    Americas

    GIS to Support Germplasm Collection for CIP Genebank

    The International Potato Center (CIP) will use the Geographic Information Systems (GIS)

    tool to support the collection of germplasm for the center's genebank and to allow

    researchers to explore potential locations for growing and finding new strains of tubers.

  • GIS will help provide CIP's genebank and its genetic resources department with a gap

    analysis of potato, sweetpotato, and other Andean roots and tubers (ARTs). A gap analysis

    is a term used to measure and identify gaps in the conservation of biodiversity by

    comparing projections against the evolution of collected materials over time in a large area.

    The tool will also map areas to show the visible effects of climate change on potato

    production. Geographic information collected by GIS is relevant to a wide range of

    different CIP projects that study the effects of climate change on potato production.

    Researchers Discover Beneficial Jumping Gene

    Geneticists at the University of California, Riverside (UCR) have discovered a transposon

    that benefits its host organism. Transposons, also called jumping genes, are DNA elements

    that multiply and change their location within an organism's genome.

    The researchers worked on Arabidopsis, and found that the COPIA-R7 transposon, which

    has jumped into the plant disease resistance gene RPP7, enhances its host's immunity to a

    pathogenic microorganism from a large group of fungus-like parasites that cause a number

    of plant diseases.

    "We provide a new example for an 'adaptive transposon insertion' event - transposon

    insertions that can have beneficial effects for their respective host organisms - and uncover

    the mechanistic basis of its beneficial effects for plants," said Thomas Eulgem, UCR

    associate professor and senior author. The research paper published by the Proceedings of

    the National Academy of Sciences is available at:

    http://www.pnas.org/content/early/2013/08/09/1312545110.abstract.

    Study Offers Insight into the Origin of the Genetic Code

    A study of enzymes that load amino acids onto transfer RNAs offers new insights into the

    evolutionary origins of the modern genetic code. Researchers from the University of

    Illinois (UI) focused on aminoacyl tRNA synthetases, enzymes that "read" the genetic

    information embedded in transfer RNA molecules and attach the appropriate amino acids

    to those tRNAs. When a tRNA is charged with its amino acid, it carries it to the ribosome,

    a cellular "workbench" on which proteins are assembled, one amino acid at a time.

    The team determined the relative ages of different protein regions called domains and

    made the simple assumption that domains found in only a few organisms are likely

    younger, and those that appear in organisms from every branch of the tree of life are likely

    the most used and most ancient.

    Gustavo Caetano-Anolls, UI professor of crop science and bioinformatics who led the

    team said, "The most ancient protein domains were enriched in dipeptides with amino

    acids encoded by the most ancient synthetases. And these ancient dipeptides were present

    in rigid regions of the proteins." He added that the domains that appeared after the

  • emergence of the genetic code were enriched in dipeptides present in highly flexible

    regions, associating genetics with protein flexibility.

    Cornell Scientists Discover 'Fountain of Youth' for Leaves

    A Cornell University research team led by Prof. Su-Sheng Gan has identified an enzymatic

    fountain of youth that slows the process of leaf death. In a series of experiments using

    Arabidopsis thaliana, the team discovered a key regulator, S3H, that acts as brake on leaf

    death. They observed that when S3H levels are low, leaves wilt early, but when it is

    present in high levels, it results in longer leaf longevity.

    The study provides insight into a highly regulated process with many molecular steps.

    According to Gan, plant senescence, or biological aging, is estimated to involve 10 percent

    of genes in the genome. Plants use a quick hypersensitive' process to block off pathogens

    by sacrificing infected cells to protect the surrounding healthy tissues.

    Gan said, "Much of the progress plant breeders have made in improving plant yields is

    actually due to delaying leaf senescence. You need long-lived green tissue to support the

    production of fruits, vegetables and seeds, so senescence limits the yield of many crops."

    Scientists Create Plants that Make their Own Fertilizer

    Washington University biologists led by Himadri Pakrasi are working on a project that will

    engineer tiny nitrogen-fixing devices within photosynthetic cells. Working through a grant

    by the joint National Science Foundation and Biotechnology and Biological Sciences

    Research Council UK project "Ideas Lab", the team plans to develop the synthetic biology

    tools needed to excise the nitrogen fixation system in one species of cyanobacterium (a

    phylum of green bacteria formerly considered to be algae) and paste it into a second

    cyanobacterium that does not fix nitrogen.

    Pakrasi said, "Ultimately what we want to do is take this entire nitrogen-fixation apparatus

    - which evolved once and only once - and put it in plants. Because of the energy

    requirements of nitrogen fixation, we want to put it in chloroplasts, because that's where

    the energy-storing ATP molecules are produced." The overall goal, in effect, is to convert

    all crops, not just legumes, into nitrogen fixers.

    Asia and the Pacific

    Former Anti-GMO Activist Pushes for Biotech Crops; Highlights Scientific Credibility of

    GMOs

  • Former anti-GMO activist and renowned British author and environmental campaigner

    Mark Lynas asserted the importance of biotech crops in addressing the challenges of food

    security during a media conference held at Dusit Hotel, Makati City, Philippines last

    August 23, 2013. Defending the importance of biotech R&D with Lynas was former

    president of the Philippine National Academy of Science and Technology (NAST) Dr.

    Emil Javier who stressed it would be of great value to the country in terms of global

    biotech competitiveness.

    According to Lynas, there is a need to grow more food from the same area of land in order

    to address the increasing food demand of a growing population and protect habitats. He

    also highlighted the importance of scientific credibility when it comes to GMOs,

    explaining that peer reviewed materials or journals should be valued more than mere

    claims. Lynas shared that his viewpoint on GM crops changed when he studied

    biotechnology as part of his research on climate change. He expressed this change of

    mindset during his lecture at the Oxford Farming Conference in January 2013.

    "I apologize for having spent several years ripping up GM crops. I am also sorry that I

    helped to start the anti-GM movement back in the mid 1990s, and that I thereby assisted in

    demonizing an important technological option which can be used to benefit the

    environment," he said.

    Lynas hails from the United Kingdom and has authored several bestselling books that

    tackle global issues including climate change and biotechnology. His book, Six Degrees:

    Our future on a hotter planet was also featured in the National Geographic Channel.

    India's Agriculture Minister Bolsters GM Crops for Food Security

    India's Union Minister of Agriculture Mr. Sharad Pawar expressing his concerns over the

    Food Security Bill, said that drastic steps, including approval of more genetically modified

    (GM) crops, need to be taken simultaneously to boost agricultural production. In an

    interview with the Indian Express, Mr. Pawar said his biggest concern was that incentives

    to the farmer may be cut to meet the subsidy burden arising from this Bill. In turn, this

    could set off a negative spiral, forcing India to import large amounts from abroad. "So for

    that purpose, we have no choice but to produce more," he added. He called for easing the

    environment for conducting field trials for GM crops. He said that India has moved from a

    net importer of cotton to the second largest exporter of cotton owing to the cultivation of

    Bt cotton.

    "There are a number of crops where our scientists have developed a good variety of

    transgenic crops but they are not even allowed to conduct trials... We should take the views

    of those who are supposed to produce and not a few NGOs," Mr. Pawar stated.

  • Stakeholders Push for GM Science Communication

    A Workshop on Practice of GM Science Communication hosted by the Chinese Society of

    Biotechnology and Platform of Science Communication for Agricultural Biotechnology

    (PSCAB) and sponsored by ISAAA China Biotech Information Center (ChinaBIC) was

    held in Beijing on August 25, 2013. Stakeholders such as academicians, scientists,

    journalists, educators, and science communicators participated the event to discuss how to

    make GM science communication more effective under the era of new media.

    Science writer Dr. Fang Zhouzi introduced strategies on how to write popular science

    articles. He suggested that the perspective when discussing the safety of GM food must be

    clear-cut . Prof. Zhang Hongxiang, Coordinator of ChinaBIC, gave an overview of the

    roles of S&T societies in public education. He said that dissemination of knowledge

    should focus on the science spirit, cultivation of science thinking, and awareness of the

    value of science research. Dr. Huang Dafang, Director of ChinaBIC called on scientists,

    journalists, educators and science communicators to form a joint force to promote GM

    public education.

    Heat-tolerant Rice Developed in Malaysia

    The Malaysian Agricultural Research and Development Institute (MARDI) has launched a

    rice variety named MRIA 1 which is heat resistant, does not require much water, and can

    be planted off-season. Developed through the collaboration with the International Rice

    Research Institute, MRIA 1 matures in 90 days and is also more disease resistant.

    Malaysia's Agriculture and Agro-based Minister Datuk Seri Ismail Sabri Yaakob, who led

    the launching of the new crop, said that the rice variety would help increase the nation's

    rice production while adapting to climate change. Annually, Malaysia imports at least 30

    percent of rice from its neighbors such as Thailand and Vietnam.

    GM Crops Pass Benefits to Weeds

    weedy form of the common rice crop Oryza sativa gets a significant fitness boost from

    glyphosate resistance even in the absence of glyphosate. In a study published this month in

    New Phytologist, Lu and his colleagues genetically modified cultivated rice species to

    overexpress its own EPSP synthase, and cross-bred the modified rice with a weedy variety.

    EPSP synthase is an enzyme blocked by glyphosate to inhibit plant growth.

    The cross-bred offspring was allowed to breed with one another, and a second generation

    set of hybrids that were genetically identical to one another was created. The results

    showed that those plants with more copies expressed higher levels of the enzyme and

  • produced more of the amino acid tryptophan than their unmodified counterparts. The

    transgenic hybrids had higher rates of photosynthesis, grew more shoots and flowers, and

    produced 48 to 125 percent more seeds per plant than non transgenic hybrids in the

    absence of glyphosate.

    Study on How Pesticides Change the Environment

    Ecotoxicologists Heinz Khler and Rita Triebskorn of the University of Tbingen have

    published a study on the link between pesticides and the changing ecological systems.

    Their study cited mathematical and experimental approaches which can help recognize the

    links between the effects of pesticides in individuals and ecological changes in biological

    communities and ecosystems in regions where intensive farming is practiced.

    The study also claims interdependent effects between pesticides and global warming. The

    researchers forecast changes to "natural" selection, the spread of infections, and the sexual

    development and fertility of wild animals. Further, they said it is a challenge for science to

    show how climate change influences the effects of pesticides, and which ecological

    systems are sensitive to this interdependence.

    The results of the study are published in the journal Science, available at:

    http://www.sciencemag.org/content/341/6147/759.full.

    New Insight on Cereal's Vernalization

  • A new research finding by European scientists revealed that flowering plants came into

    being when duplications took place in the genome of their ancestors. The researchers found

    large numbers of DNA duplications in the very parts of the genome that are unique to

    flowering plants. Furthermore, the study provides insight on cereal's vernalization, a

    process wherein plant acquires the ability to flower in the spring after its long exposure to

    winter.

    The vernalization gene the so-called FLC gene, seen in other plants requiring a cold

    period in order to be able to flower has not previously been found in winter cereals.

    However, now that the researchers knew exactly where they had to look, they were able to

    find genes related to FLC genes. This gave new direction to the study of vernalization in

    cereals.

    Scientists Create Three-dimensional Model of Bacterium

    A team of scientists from Heidelberg University and the European Molecular Laboratory

    has succeeded in building a three-dimensional model of the Gemmata obscuriglobus

    bacterium including the structure of its membrane system. The team discovered that certain

    bacteria can build complex membrane structures that make them look like eukaryotes. The

    genetic material of G. obscuriglobus was surrounded by a double membrane, a

    characteristic called into question in the differentiation between prokaryotes and

    eukaryotes.

    The studies done by the scientists from Heidelberg University showed that the membranes

    within the G. obscuriglobus are only part of the interior membrane present in all bacteria

    and that surrounds the cytoplasm. According to the team, the results of their study disprove

    the assumption of the existence of a bacterial cell nucleus. The cell ctructure and

    membrance of G. obscuriglobus are simply more complex than in "classic" bacteria, and it

    cannot be classified as a eukaryote.

    Research

    Whole-Genome Analysis of GM Rice Expressing Edible Vaccine Against Pollen Allergy

    Agrobacterium-mediated transformation is one of the most utilized techniques in

    introducing novel traits in crops. Through this technique, a tumor-inducing DNA molecule

    from Agrobacterium tumefaciens is inserted to the host genome. However, it is still not

    explained how the host genome is modified by this event at single-base resolution.

    Researchers from National Institute of Agrobiological Sciences led by Taiji Kawakatsu

    conducted a whole-genome sequencing of GM rice line OSCR11 to evaluate the genetic

    difference of GM crops and their host. OSCR11 expresses a seed-based edible vaccine

    with two major pollen allergens (Cry j 1 and Cry j 2) against Japanese cedar pollinosis.

  • Results showed that the genetic difference between OSCR11 and its host (a123) were

    significantly less than those between a123 and its background cultivar Koshihikari. The

    nucleotide base substitution present in OSCR11, relative to a123, was similar with

    somaclonal variation. Mutations in OSCR11 might have happened during the cell culture

    steps. Further analysis showed similar RNA molecules of a123 and OSCR11, maintaining

    genomic integrity between them.

    Beyond Crop Biotech

    Shutting Down Reproductive Ability to Control Insect Pests

    Natalisin, a neuropeptide was recently found by Kansas State University entomologists led

    by Yoonseong Park to regulate the sexual activity and reproductive ability of insects.

    According to Park, natalisin is part of insect's and arthropods' genetic network that uses

    small peptides as neurotransmitters to chemically relay messages throughout the body. In

    the three insects studied: fruit fly, red flour beetles and silk moths, natalisin was expressed

    in three to four pairs of neurons in the brain.

    Silencing of natalisin in the brains of these insects led to their inability to reproduce as well

    as reduced their interest in mating. This neuron knockdown will help scientists develop

    targeted control methods for insect pests that would be environmentally safe. Since

    natalisin is only found in insects, a future insecticide would not affect plants, animals or

    humans.

    Document Reminders

    European Union Agricultural Biotechnology Annual Report

    A Global Agricultural Information Network report on Agricultural Biotechnology in the

    European Union (EU) was recently released by USDA Foreign Agricultural Service. The

    document describes how various stakeholders remain conflicted about the use of

    agricultural biotechnology such that acceptance varies greatly among adopters, the

    conflicted, and opposed Member States (MS). Government policy in the EU and MS on

    plant and animal biotechnology is complex and lengthy that slows down and limits

    research, development, production, and imports. There are however five MS which have

    increased planting of geneticially modified corn and the EU has been a major consumer of

    million tons of genetically modified soybean and corn products imported every year. It has

    been increasingly difficult and expensive for EU companies to source non-biotech products

    and ingredients for food products that are labeled as non-GMO.
