| LESS POPULAR CROPS KEY TO SOLVING HUNGER, MEETING REPORTS
More research on neglected but nutritious crops can be the solution to hunger.
This is according to agriculture and biodiversity experts who met during the
International Consultation on the Role of Biodiversity in Achieving the United
Nations Millenium Development Goal of Freedom from Hunger and Poverty held
in Chennai, India. They also said that a more varied selection of native crops
can provide greater dietary diversity. Some examples of these crops are varieties
of millet in Asia; quinoa, canihua, and amaranth in South America; and green
leafy vegetables in Africa.
This undertaking is believed not only to address the first
UN Millenium Development Goal to “reduce by half the number of people who suffer from hunger”,
but also two others: to reduce infant mortality and the number of women who
die in childbirth.
The meeting was organized by the International Plant Genetic
Resources Institute and Global Facilitation Unit for Underutilized Species,
both from Rome, with
the M.S. Swaminathan Research Foundation from Chennai. Recommendations from
the meeting are being finalized to be part of UN’s review on the progress
of its Millenium Development Goals in September.

EU MAY LIFT BANS, ALLOW NEW GM CROP FOR PLANTING
The European Commission (EC) has drafted proposals for the Council of Ministries
for five member states to lift their bans on genetically modified organisms
(GMOs). These are the GM maize varieties T25 and MON810 in Austria; GM maize
Bt176 in Austria, Germany, and Luxembourg; oilseed rape variety MS1xRF1 in
France; and Topas 1912 in France and Greece. The proposals are supported by
the European Food Safety Authority (EFSA).
The Council will vote on whether to adopt or reject the proposals. If there
is no decision made by the required majority in three months, the proposals
will be returned to the Commission for adoption. If adopted, the countries
concerned will have to lift their bans after at most 20 days from their notification.
In related news, European Union (EU) officials recently announced that their
environment experts may vote in June on allowing a new genetically modified
(GM) crop to be grown in Europe, a first attempt since 1998. The debate on
the crop, 1507 maize, is tentatively scheduled on June 6 and is still pending
confirmation.
The EU has recently lifted its six-year ban on GM imports,
but there still has been no go-signal to plant any GM crop in Europe since
1998, as EU’s
25 member countries are “deeply divided on the issue.”

IMPROVED VERSION OF GOLDEN RICE UNVEILED
Golden rice 2, a new version of genetically modified (GM) rice by United Kingdom
(UK) and US scientists from Syngenta Biotechnology Inc., is estimated to provide
50% more of the recommended daily allowance (RDA) of vitamin A for children,
compared to the first version. This was featured in the April issue of Nature
Biotechnology.
Golden rice is a crop engineered to produce beta-carotene, a yellow-orange
pigment converted by the body into vitamin A. Golden Rice 2 has more than 20
times the amount of beta-carotene or pro-vitamin A. It also contains a version
of phytoene synthase (the first in the beta-carotene pathway) from maize, which
was found to produce the most beta-carotene from all the enzymes screened.
Syngenta, as a part of the Humanitarian Project for Golden Rice, plans to
donate the strain to other researchers for further study and improvement.

NEW TOOL AVAILABLE FOR BIOTECH INFORMATION SHARING
A new tool for the biotechnology industry can enable researchers or companies
to access patented technologies for their work. Introduced by CAMBIA, an Australian
non-profit biotech research organization, this is the Biological Innovation
for Open Society (BIOS).
BIOS is an open
source license wherein biotech innovations can be distributed. It applies
the same approach in open source licensing in the computer industry.
In this manner, a scientist's improvement on a licensed technology can be accessed
by the community for commercialization. Scientists can also start on a new
project, join an ongoing one, or share information through BioForge (http://www.bioforge.net),
where BIOS participants can meet in the Web. However, those who accessed knowledge
have to contribute their own improvements back into the licensing pool.
One of the recent technologies made available through BioForge was Trans-Bacter,
a new method of gene transfer to plants using other bacterial species aside
from the usual Agrobacterium tumefaciens. With this, it was discovered that
several other bacterial species can transfer genes, not only Agrobacterium.
Richard Jefferson, CEO and chief scientist at CAMBIA, believes
that "when
you start having tens or hundreds of patents necessary to reduce to practice
one idea, then it becomes untenable. And basically innovation grinds to a halt." With
BIOS, those in the public sector, small biotech companies, and developing countries
can now access technologies for their own improvements.

RICE BLAST FUNGUS GENOME SEQUENCE REPORTED Dr. Ralph Dean of the Center for Integrated Fungal Research, North Carolina
State University and colleagues recently presented a rough draft of the genome
sequence of the rice blast fungus Magnaporthe grisea. Their findings are reported
in a recent issue of Nature.
M. grisea is the most destructive pathogen of rice worldwide, and is estimated
to destroy enough rice yearly to feed 60 million people. Its different forms
can also affect a broad range of grass species including wheat, barley, and
millet.
The research team found a few genome qualities unique to M.
grisea, 9.7% of which consists of repeating sequences. So far, their draft
shows that M. grisea’s
genome encodes a large and diverse set of secreted proteins, with an expanded
family of G-protein-coupled receptors, several new virulence-associated genes,
and large suites of enzymes involved in secondary metabolism. The draft also
shows that the genome contains 11,109 genes with protein products of longer
than 100 amino acids.

PROTEIN COILS GUIDE CAMV, RESEARCH SAYS
“A coiled-coil interaction mediates cauliflower mosaic virus cell-to-cell
movement,” Livia Stavolone of the Friedrich Miescher Institute, Switzerland
and colleagues report in the latest issue of the Proceedings of the National
Academy of Sciences (PNAS) online.
The Cauliflower Mosaic Virus (CaMV) uses various proteins in invading plant
cells. The Virion Associated Protein (VAP) mediates virus transmission by aphids,
and contributes to the spread of an infection within a plant host. The movement
protein (MP), on the other hand, is thought to associate with the VAP and contribute
to infection as well.
Through studies on the proteins involved, as well as investigations
made on the interactions between these proteins, researchers found that one
end of
MP interacts with VAP. MP’s end is a coiled-coil of amino acids, which,
through their conformation, interact with another coiled-coil at the end of
VAP. Together, the VAP-MP pair move to plant plasmodesmata and contribute to
the spread of CaMV infection in the host.
Previous research has shown that, in both plant and animal systems, coiled-coil
domains do facilitate interactions between distinct proteins. Knowing how CaMV
travels from vector to host can be thus be important in finding ways to disable
it and prevent it from spreading to healthy plants.
