2005: A Year of Success for Plant and Animal Biotechnology
WASHINGTON, Jan. 4 /PRNewswire/ -- "Significant achievements were made in the adoption and acceptance of agricultural biotechnology for improved crops and animals in 2005," said Sean Darragh, executive vice president of the Biotechnology Industry Organization (BIO).
"A major milestone was reached in May when the one billionth acre of biotech crops was sown capping a decade of plantings in 18 countries around the globe," added Darragh. He also pointed out that more than 90 percent of the 8 million farmers growing biotech crops were located in developing nations.
"While the first generation of plant biotech products directly benefited farmers and the environment, the next generation of plant biotech research is focused on providing consumer benefits, including the development of biotech plants that offer increased nutrition and health benefits," said Darragh.
In addition to record acceptance by farmers, scientists continued to increase their understanding and knowledge of plants and animals through genome sequencing projects. In 2005, the rice and dog genomes were mapped, and projects to sequence soybean, corn, and sheep genomes were announced. Researchers use these genetic maps to improve the nutrient quality of food crops and strengthen plants' abilities to resist drought conditions, insect infestation and plant disease. In addition, by understanding the makeup of animals at a cellular level, scientists can develop leaner and more nutritious dairy and meat products, as well as help animals to live healthier lives.
An example of the importance of developing nutrient-enhanced biotech plants, especially for developing countries, were $36.8 million in grants to research projects focused on improving nutrition and health through biotech- improved bananas, cassava, rice, and sorghum by the Bill and Melinda Gates Foundation.
2005 also saw other important biotech developments with consumer benefits including:
* Kellogg announced it will use low-linolenic soybean oil to reduce or
eliminate trans fats in several of its products; though the soybeans
were produced through conventional breeding techniques, they do contain
biotech traits and are the first products in the next generation of
biotech products with consumer benefits.
* Australian researchers developed a biotech improved cress that contains
healthy omega-3 oils in their seeds. Omega-3 oils are known to help
reduce the risk of heart disease.
* Research into edible vaccines continued with the development of a
biotech potato that carries the Hepatitis B vaccine, and a biotech
tomato containing a SARS vaccine. Initial tests in human subjects have
shown that the biotech potato confers immunity against Hepatitis B.
Japanese scientists also announced the development of an edible vaccine
in biotech rice that prevents the immune response that triggers
allergies related to hay fever.
* Japanese researchers developed a biotech soybean that contains a
substance that promotes hair growth and helps prevent hair loss caused
by chemotherapy. An antihypertensive substance derived from egg whites
was incorporated into the soybean; the substance expands blood vessels
and promotes circulation and hair growth.
There were also advances in animal biotechnology research which will lead to improved animal health, more nutritious and safer food products from animals, advances in human health, and conservation of both the environment and endangered animals. They include:
* USDA biotech researchers announced a breakthrough that will help cows be
naturally resistant to mastitis, a bacterial infection of cows' milk
glands that causes inflammation and swelling and a loss in milk
production. The biotech cows produce the protein lysostaphin, which
significantly decreases the likelihood of developing mastitis, which
causes up to a $2 billion loss annually for dairy farmers in the United
States.
* Chickens, cows and pigs were improved through biotechnology as part of
research to improve human health. In June, Scottish scientists
developed a method of producing antibodies that treat malignant skin
cancer in chicken egg whites improved through biotechnology. The new
production technique could allow for the development of a wide range of
cancer treatments in greater volume and in a more cost-efficient method
than conventional manufacturing techniques.
* In Argentina, cows were improved with biotechnology to produce human
growth hormones in their milk. Scientists estimate that just 15 of
these Jersey cows could produce enough human growth hormone to meet the
current world demand for the hormone.
* Work continued in South Korea on xenotransplantation, with piglets
improved through biotechnology that contain an "HLA-G" gene, which give
their organs an increased change of acceptance if transplanted into
humans. Immuno-rejection is one of the major hurdles to
xenotransplantation; the introduced gene in the cloned piglets may
reduce the chance of organ rejection.
* In animal conservation, an endangered species of Mongolian gazelle was
cloned for the first time. 2005 also marked several other animal
cloning firsts, including water buffalo and an Arab endurance champion
horse. In addition, the United Kingdom announced approval to clone
horses for research using somatic nuclear transfer techniques.
And finally, throughout the year, many international organizations continued to add to the collection of scientific literature that highlights the benefits of agricultural biotechnology:
* The World Health Organization (WHO) reported that biotech foods can
"contribute to enhancing human health and development." The study found
that biotech foods can increase crop yield, food quality, and the
diversity of foods which can be grown in a given area, and lead to
better health and nutrition, and thereby raise health and living
standards.
* A report issued by USDA's Economic Research Service (ERS) and Rutgers
University also found that large farms and small-scale farmers in
southern Africa can benefit from planting biotech corn. The report
found that yields on large farmers increased about 11 percent, and
yields for small farms increased anywhere from seven to 56 percent, when
biotech corn was planted.
* A National Center for Food and Agriculture Policy (NCFAP) study found
that the 118 million acres of biotech crops U.S. farmers planted in 2004
increased food production by 6.6 billion pounds, and provided $2.3
billion in additional net returns for U.S. growers. Biotech crops also
reduced pesticide use by an additional 34 percent, or 15.6 million
pounds.
* The British research firm PG Economics Ltd. found that the global use of
biotechnology-derived crops has added $27 billion to farm income and
greatly reduced agriculture's negative impacts upon the environment.
* An April, Science published a study by researchers at Rutgers University
and the University of California, Davis who found that biotech rice in
China could decrease farmer's production costs, increase harvest yields,
reduce the use of pesticides by as much as 80 percent, and improve
farmer health. The study also estimated that if "90 percent of the
farmers plant [biotech] rice, the annual agricultural income of China
will increase by $4 billion."
* A study by the University of Connecticut and Japan's Kagoshima
Prefectural Cattle Breeding Development Institute found that meat and
milk products from cloned cattle are safe for consumption. The results
reiterate those found by the National Academy of Science in 2001.
