Jazzing up Jasmine:
Atomically Modified Rice in Asia?
A nanotech research initiative in Thailand aims to atomically modify the
characteristics of local rice varieties - including the country's famous
jasmine rice- and to circumvent the controversy over Genetically Modified
Organisms (GMOs). Nanobiotech takes agriculture from the battleground of GMOs
to the brave new world of Atomically Modified Organisms (AMOs).
In January, Bangkok Post reported on a three-year research project at Chiang
Mai University's nuclear physics laboratory,(1) funded by the National
Research Council of Thailand, to atomically-modify rice. The research
involves drilling a nano-sized hole (a nanometer is one-billionth of a meter)
through the wall and membrane of a rice cell in order to insert a nitrogen
atom. The hole is drilled using a particle beam (a stream of fast-moving
particles, not unlike a lightening bolt) and the nitrogen atom is shot
through the hole to stimulate rearrangement of the rice's DNA.
Pipe Dreams from Particle Beams? One of the attractions of this technique,
according to the director of the Fast Neutron Research Facility in Chiang Mai
where the research is being conducted, is that it does not require the usual
(and controversial) technique of genetic modification, where genes are
transferred between unrelated organisms or are removed or rearranged within a
species. "At least we can avoid it," Thiraphat Vilaithong, the Facility
director said.(2)
"We don't consider atomically modified rice any safer or more socially
acceptable than genetically modified rice," explained Witoon Lianchamroon of
Biodiversity Action Thailand (BIOTHAI), a civil society organization based in
Bangkok. "It sounds like the same high-tech approach that does not address
our needs and could cause severe hardships for Thai rice farmers."
According to BIOTHAI, scientists at Chaing Mai University have already used
nanotechnology to modify the colour of a local rice variety, "Khao
Kam."(3) The word "Kam" means deep purple, and the rice variety is known for
its purple stem, leaves and grains. Using nanotechnology, the scientists
changed the colour of the leaves and stems of Khao Kam from purple to green.
In a telephone interview, Dr. Thirapat Vilaithong told BIOTHAI that their
next target is Jasmine rice. The goal of their research is to develop Jasmine
varieties that can be grown all year long, with shorter stems and improved
grain colour.
The research at Chiang Mai is related to other types of "mutation breeding" in
that the cell's DNA is manipulated to cause a change in gene function. The
difficulty lies in finding safe passage through a plant cell's wall and
membrane without compromising the cell's ability to survive or allowing
essential cellular contents to leak out. Mutation breeding and nuclear
physics have a long history, with most work coming out of a joint United
Nations Food and Agriculture Organisation/International Atomic Energy Agency
programme in Vienna beginning in the mid-1960s. Over the last 40 years,
researchers there have bombarded plant cells with x-rays, beta and gamma
rays, among other particles, to induce alterations in the genomes of crop
plants.(4)
The Bigger Picture: The project being undertaken at Chiang Mai's nuclear
physics lab is a testament to Thailand's commitment to nanotechnology. In
January, the Prime Minister, Thaksin Shinawatra, ordered the establishment of
a nanotechnology center to be headed by the government's National Science and
Technology Development Agency (NSTDA).(5) In addition to the rice project,
researchers in Chiang Mai are working to alter the surface of silk at the
nanometer level to make it water- and dirt-resistant, hoping to give Thailand
a competitive advantage over the world's other major silk exporters, which
include India and China. Industry analysts predict that the nanotech
revolution will someday allow researchers to engineer new materials and
modify existing ones so that they exhibit whatever property is most desirable
for a given application - strength, weight, electrical conductivity, colour
could all be manipulated at the molecular level. In theory, production,
including agricult
ural production, would no longer be dependent on geography, labour or raw
materials, rendering some natural resources obsolete - with especially
serious disruptions for Third World economies.
"Oops, There Goes Another Rubber Tree Plant:" For example, consider the
potential of nano-scale innovations to affect the market for rubber:
researchers in the US are designing nanoparticles to strengthen and extend
the life of automobile tyres as well as new nanomaterials that could be used
as a substitute for natural rubber, especially in medical gloves. "If
nano-designed tyres and other products require little or no rubber in the
future, it will mean less demand for natural rubber with potentially
devastating impacts for the livelihoods of rubber tappers and plantation
workers worldwide," explains Jim Thomas, ETC Group researcher from Oxford UK.
Malaysia and Thailand are currently the world's top producers of natural
rubber.
Prime Minister Thaksin is placing special emphasis on research in
nanobiotechnology, such as the atomically modified rice project, in an effort
to distinguish Thailand from other regional nanotech research. Because living
and non-living material are indistinguishable at the nano-scale - at this
fundamental level, they are both simply atoms and molecules of chemical
elements - physicists, genetic engineers and material scientists are
exploiting this "material unity at the nano-scale" to combine biological and
non-biological material in unprecedented ways. While global investment in
nanotechnology - both private and public - is estimated between five and six
billion dollars (US) per annum, the focus on nanobiotechnology is
significant. Since 1999, venture capitalists alone have devoted over $450
million to nanobiotechnology.
The rice research in Thailand is just one small piece of the nanobio picture
related to food and agriculture. According to Helmut Kaiser Consultancy,
some 200 transnational food companies are currently investing in nanotech and
are on their way to commercializing products. The list includes many of the
world's largest companies: Ajinomoto, Campbell Soup, ConAgra, General Mills,
H. J. Heinz, Kraft Foods, McCain Foods, Nestlé, PepsiCo, Sara Lee, Unilever,
and more.
Miracle Rice Re-visited? The United Nations has designated 2004 the Second
International Year of Rice. Neth Daño, executive director of SEARICE in the
Philippines, recalls that the first International Year of Rice was
thirty-eight years ago in 1966, the year that the International Rice Research
Institute (IRRI) launched the Green Revolution in Asia with the release of
IR8, the first semi-dwarf rice variety. "The so-called 'miracle rice'
required irrigation and a costly package of chemical fertilizers and
pesticides that drove poor farmers deeper into debt," said Daño. "IR8 was not
only highly susceptible to pests and diseases, it also introduced massive
genetic uniformity, displaced poor farmers and their traditional rice
varieties."
"Will 2004 bring us full circle?" asks Kathy Jo Wetter, ETC researcher. "At
what cost to farmers, food security and the environment are researchers now
tinkering with atomically-modified rice? Will 2004 be remembered as the year
that launched atomically-modified rice and the Nano-Rice Revolution?"
Both ETC Group and SEARICE are members of the CBDC Programme (see box, below).
Later this year ETC Group plans to release an in-depth report on impacts of
nanobiotechnology for food and agriculture, especially in the developing
world. The report will also consider food industry applications, such as
nanosensors embedded in food packaging and in food itself, "interactive" food
and beverages - products that would change colour, flavour or nutrients to
accommodate the individual consumer's tastes or health condition, and
ultrasound-activated animal vaccines using nanoparticles, among many others.
