Global
MINISTERS
APPROVE DECLARATION TO IMPLEMENT PLANT TREATY
Ministers
of Agriculture approved a Ministerial Declaration for
countries who ratified the International Treaty on
Plant Genetic Resources for Food and Agriculture to
fully implement it at the national level. Representatives
from 70 countries attending the Madrid meeting of the
first Board meeting of the Treaty also pledged to enhance
national capacities for the conservation and sustainable
use of plant genetic resources.
Food
and Agriculture Organization Director-General Jacques
Diouf called on countries to have the political will
to guarantee the Treaty's implementation. He described
the international accord as "a fundamental tool
in humanity's efforts to do away with hunger and malnutrition."
Diouf
enumerated the following initial effects of the Treaty:
Increased
international sharing of plant genetic resources;
- Enabled
developing countries to conserve and make better
use of their own plant genetic resources as well
as those they obtain internationally;
- Raised
awareness of farmers’ rights and the central
role they play in the conservation and use of genetic
resources.

DEVELOPING
COUNTRIES FACE LESS RESEARCH INVESTMENTS
The
shift in balance in global agricultural research investments
will have long term consequences especially for the
poor. Changes in the supply and demand for agricultural
technologies in many of the world’s richest countries
will result in a scenario where they will be unable
to provide quantities of productivity-enhancing technologies
suitable for adaptation and adoption in poor countries.
This trend was discussed in “Shifting ground:
Agricultural research and development worldwide” by
Philip Pardey and colleagues.
The
issue brief released by the International Food Policy
Research Institute (IFPRI) noted that this trend is
aggravated by reduced support by developed countries
for the international agricultural research system
particularly for technologies for staple food crops.
As a consequence, developing countries will have to
become more self-reliant in developing applicable agricultural
technologies.
A
scientific and productivity gap might occur, the authors
note, requiring a rethinking of some national and multinational
policies. Governments can consider enhancing intellectual
property rights and putting in place appropriate local
policies; increasing government funding for national
agricultural research systems; and introducing incentives
to encourage private sector funding.

Africa
KENYA
RELEASES NEW IMPROVED BEAN VARIETIES
Three
new climbing bean varieties and two bush bean varieties
have been approved for pre-release by the Kenyan bean
national variety release technical committee. Kenya
is the leading bean producer in Africa, however yields
are typically low, and demand for beans in the country
exceeds local production levels. This is the first
time that climbing bean varieties, which have yields
three times higher than those of bush bean lines, are
released in Kenya.
The
new varieties were developed by the Kenyan Agriculture
Research Institute (KARI) Kakamega Research Center,
the University of Nairobi, Kenya Seed Company, and
by Western Seed Company. The lines developed by the
public institutions were obtained or derived from the
germplasm collection of the International Centre for
Tropical Agriculture (CIAT), and were distributed through
the collaborative regional bean breeding program based
at the University of Nairobi.
Kenya
last released improved bean varieties in 1997. Read

USAID
TO STRENGTHEN PLANT INSPECTION SERVICES IN AFRICA
The
U.S. Agency for International Development (USAID) will
provide funds to strengthen plant health inspection
services required for African countries to trade fruits
and vegetables in the global market. This was announced
during the Fifth Annual African Growth and Opportunity
Act Forum in Washington, DC. African countries will
then be able to export horticultural products that
meet international standards.
The
plant inspection program is part of the $200 million
African Global Competitiveness Initiative (AGCI) that
aims to improve among others, the policy, regulatory
and enforcement environment for private-sector led
trade and investment. In addition to conducting assessments
for fruits and vegetables, the Initiative also provides
assistance to improve agricultural productivity, as
well as safeguard plant health and the environment.

NIGERIA
LOOKS TO BIOTECH TO AID FOOD SECURITY
A
series of biotechnology awareness workshops for policy
makers in Nigeria is being spearheaded by the Nigeria
Agriculture Biotechnology Project (NABP) to help address
issues related to hunger, poverty and diseases. Noting
that “Biotechnology is our time”, Babatunde
Solomon, Director General of the Nigerian Biotechnology
Development Agency, told policy makers of the North
Central States in Nigeria during a workshop in Lafia,
Nasarawa State, that the country should not miss the
opportunities that biotechnology can offer.
Solomon
added that effective application of biotechnology has
led to the emergence of small and medium, highly scientific
and technologically advanced firms with a variety of
linkages to public research sector, and large scale
enterprises.
The
NABP is being promoted by the National Biotechnology
Development Agency (NABDA) representing the Federal
Government of Nigeria. It is being implemented by the
International Institute of Tropical Agriculture (IITA).

CUBA
REGISTERS FIRST MONOCLONAL ANTIBODY MADE IN BIOTECH
PLANTS
The
Center for genetic Engineering and Biotechnoloy (CIGB)
of Cuba has registered the first monoclonal antibody
produced in transgenic plants. The antibody has been
approved by the Center for the State Center for the
Control of the Quality of Pharmaceuticals (CECMED),
the regulating authority of the Ministry of Public
Health of Cuba, and it has also obtained approval by
the National Center for Biosafety, under the Ministry
for Science, Technology and the Environment.
The antibody will be used to purify the active ingredient used in the Cuban
vaccine against hepatitis B, commercialized as Heberbiovac-HB, said Carlos
Borroto, deputy director of CIGB. Borroto explained that, in comparison with
the traditional vaccine produced mice, the vaccine obtained from biotech tobacco
plants offers greater levels of security. In addition, Borrot indicated that
the CIGB has taken adequate measures to avoid possible environmental risks
during the cultivation of the transgenic crop, by growing the plants in confined
conditions.

BRAZIL,
BIOTECH NEEDED FOR COPING WITH DROUGHT
A
partnership between Brazilian and Japanese public research
institutions could address some of the severe crops
losses caused by drought in Brazil, said Alexander
Nepomuceno, researcher of the Brazilian Agricultural
Research Corporation (EMBRAPA). During the 2004/2005
growing season the Brazilian State Rio Grande Do Sul
had a loss of 70% in the production of soybeans due
to water scarcity, while crop losses in Paraná State
amounted to 22%.
In
an interview to the Brazilian National Radio, Nepomuceno
explained that three-year collaborative research project
between the two nations on a gene from thale cress
called DREB (for Dehydration Responsive Element Binding
Protein). Expression of DREB induces the activity of
additional genes needed to protect the plant when water
is scarce. This technology could be used to increase
the tolerance of crops to drought thereby minimizing
losses. Brazil, according to Nepomuceno, is the only
great producer of grains that lacks legislation favorable
to biotechnology, citing the United States, Argentina,
Australia, Canada, and China as examples of nations
active in developing and commercializing biotech crops. “It
is complicated for a country such as ours, with the
potential that Brazil has for agriculture, for producers
not to have this option” affirmed Nepomuceno,
and added that most of these technologies are intended
for benefit of small scale farmers.
EMBRAPA
is hoping to carry out the first field trials of drought
resistant varieties in 2007, as soon as it receives
approval by the Brazilian National Technical Commission
for Biosafety (CTNBio).

VEGETABLE VARIETY
PROTECTION DISCUSSED IN MEXICO
Scientists
and specialists from 15 countries met this week in
Mexico to discuss the protection of new vegetable varieties,
with the aim of advancing agricultural research and
development and promoting the transfer of technology
for the benefit of rural communities. Francisco Mayorga
Castañeda, Minister for Agriculture of Mexico,
said during the opening ceremony of the Session for
the Technical Working Party for Vegetables of the International
Union for the Protection of New Varieties of Plants
(UPOV) that agricultural development is based on scientific
research and knowledge. Effective protection systems
for new crop varieties are therefore essential as an
incentive for innovation and for promoting the transfer
of technology.
“The
advance of science and technology, without a social
advance, is losing our way” said Mexican Governor
Juan Carlos Romero. It is very important we take advantage
of the possibilities science offers today to ensure
food security and to raise the quality of life of rural
society, added Romero.
UPOV
is an intergovernmental organization aimed at promoting
an effective system of plant variety with the aim of
encouraging the development of new varieties of plants
for the benefit of society.

ICRISAT
INTRODUCES NEW GROUNDNUT VARIETY
The
Chief Minister of Andhra Pradesh, India, Dr Y S Rajasekhara
Reddy, presented the groundnut variety ICGV 91114 to
the farmers of the country’s Anantapur district
at a recently concluded function at the Patancheru
campus of the International Crops Research Institute
for the Semi-Arid Tropics (ICRISAT). The new variety,
developed by ICRISAT, will improve the income of the
farmers of the district, while protecting them from
drought risk.
The
new groundnut variety produces yields of about 10%
more than current popular variety TMV2. Farmers of
Anantapur prefer to cultivate groundnut, as it can
grow on the area’s rough terrain, and can survive
with little rainfall.

MOLECULAR
FARMING DISCUSSED IN MALAYSIA
As
Malaysia moves on to strengthen its agricultural biotechnology
sector, various areas have been identified as potential
generator of wealth. One of the areas of interest is
using plants as factories or bioreactors to produce
high value proteins and pharmaceuticals. Though, this
discipline is still at an infancy stage, a group of
scientists at the Centre for Research in Biotechnology
for Agriculture (CEBAR) in University of Malaya is
actively involved in spearheading research in this
field. This week, an International Symposium on Molecular
Farming in Plants: Prospects for Asia was organized
by CEBAR in collaboration with Malaysian Biotechnology
Information Centre (MABIC) and International Islamic
University Malaysia (IIUM).
The
conference is a proactive move on the part of the co-organisers
in stimulating real time discussion and knowledge sharing
on what could potentially be a huge growth area for
biotechnology in Asia. Advantages that have been put
forward for plant bio-factories include lower capital
and operating costs, economic scale-ups, easy storage,
production of protein products fold and assemble correctly,
just like their counterparts in mammalian cell culture
and the fact that plants do not host human or animal
pathogens.
The
symposium featured leading scientists in this field
from various countries as keynote speakers. Prof. Ed
Rybicki from University Cape Town, South Africa; Prof.
James Dale from Queensland University of Technology,
Australia; Prof. Z Nicolav from Texas A&M University,
USA; Mr. Francois Arcand from Spain, Dr. Dwayne Kirk
from Monash University, Australia; Prof. Rainer Fischer
from Fraunhofer Institute, Germany were among some
of the speakers.
The
symposium was officiated by the Deputy Minister of
Science, Technology and Innovation who mentioned that
the Malaysian Government places great emphasis on agriculture
as a major thrust in biotechnology. Under the 9th Malaysia
Plan, the Government has allocated a budget of RM 11.4
billion to transform the agricultural industry into
a modern, dynamic and competitive force.

BIOTECH
CROPS THAT PRODUCE NON-GM POLLEN
The
lateral gene transfer or “escape” of transgenes
into the environment is a major biosafety concern.
Pollen from biotech crops could fertilize conventional
varieties or wild species, thereby releasing the transgene
with potential adverse effects on biodiversity.
The
use of Genetic Use Restriction Technologies (GURTs),
which can be used both to develop sterile plants and
to regulate the expression of the transgene by the
application of chemicals or by a specific set of environmental
conditions, have been proposed as a tool to prevent
lateral gene transfer. These technologies have however
met with considerable opposition.
The
possibility of producing essential vaccines and medicines
in biotech plants makes the need to prevent lateral
gene transfer essential, especially when food crops
are used for biopharming. Biopharming can potentially
benefit developing countries most, where the lack of
infrastructure, road access and refrigeration are often
major constrains to delivering required pharmaceuticals
to where there are most needed. Edible medicines would
be cheaper to produce, purer, easier to transport,
and would require no refrigeration.
Can
we develop biotech crops that produce GM-free pollen
and are also fertile? A team of researchers, lead by
Jan-Peter Nap of the Wageningen University in the Netherlands,
show us we can. The group generated transgenic tobacco
plants that carry, in addition to the transgene of
interest, a second gene that will excise the first
transgene. The team ensured the second gene is only
active during reproduction by using a pollen specific
promoter. Transgene removal becomes therefore an integral
part of the biology of pollen maturation, and does
not require any external stimulus or chemical application.
Highly efficient excision of transgenes from tobacco
pollen was achieved with a potential failure rate of
at most two out of 16 800 seeds (0.024%).

PLANT
ANTIBODIES SHOW ANTI-CANCER ACTIVITY IN RESEARCH
A
number of therapeutic antibodies can actually help
kill cancer cells. They do this by binding to antigens
expressed on the surface of cancer cells, which triggers
a cell death process which leads to the eradication
of abnormal cell types. For instance, one monoclonal
antibody called BR55-2 recognizes the Lewis Y antigen
(LeY), an antigen over-expressed on breast, lung, ovary,
and colon cancers. Demand for such antibodies is growing
quickly, but production methods can manufacture only
limited quantities, and at high cost. As a result,
scientists are exploring plants as possible antibody
factories.
Robert
Brodzik and colleagues of Thomas Jefferson University,
Philadelphia and University Medical Center Utrecht,
The Netherlands report that “Plant-derived anti-Lewis
Y mAb exhibits biological activities for efficient
immunotherapy against human cancer cells.” Their
article, which appears in a recent edition of the Proceedings
of the National Academy of Sciences, describes the
production of BR55-2 in transgenic low-alkaloid tobacco
plants.
The
subunits of BR55-2 were expressed separately, and subsequently
assembled in plant cells of tobacco plants. Researchers
grew the plants, isolated the transgenic BR55-2, and
assayed its activity. They found that: 1) antibody
expression was high in the transgenic plants; 2) like
mammalian-derived antibodies, plant antibodies bound
specifically to both breast cancer and colorectal cancer
cells, and also initiated cancer cell death; and 3)
plant-derived BR55-2 inhibited tumor growth in immuno-suppressed
mice. Together, these findings show that plant-derived
antibodies have potential for efficient immunotherapy.

EARTHWORMS
NOT AFFECTED BY BT CORN, RESEARCH FINDS
Bt-corn
is genetically engineered to express toxins that will
protect corn against lepidopteran pests. Because Bt
corn is widely planted, it is important to evaluate
the potential risks of the Bt protein to non-target
organisms, such as earthworms. Earthworms are important
to the aeration and nutritional content of soils; they
are also important to corn grown in reduced tillage
practices, since earthworms can maintain and improve
soil physical conditions.
Only
a few studies have dealt with the effects of Bt protein
on earthworms, and Maria Laura Vercesi and colleagues
of National Environmental Research Institute, Denmark
add their own research to the tally as they ask: “Can
Bacillus thuringiensis (Bt) corn residues and Bt-corn
plants affect life-history traits in the earthworm
Aporrectodea caliginosa?” In a recent issue of
Applied Soil Ecology, the authors report the effects
of Bt-corn on survival, reproduction, and growth of
the most widespread earthworm species in temperate
agricultural soils.
Researchers
tested the effects of finely ground Bt corn cultivar
MEB307 leaves in soil on A. caliginosa, including concentrations
that would be considered “worst case scenario.” They
also tested the effects of Bt protein on earthworms
by raising juveniles in soils in potted corn plants.
After statistical analysis of their results, researchers
recorded the following: 1) no earthworm adults died
in the reproduction experiments with finely ground
corn leaves; 2) there were no significant differences
in juvenile growth curves between Bt and non-Bt exposed
earthworms, but earthworm growth was drastically reduced
in non-Bt plants treated with benomyl, a fungicide
toxic to earthworms; and 3) there was slightly reduced
cocoon hatchability of earthworms exposed to Bt corn.
Despite
the decreased hatchability, scientists concluded that
Bt corn residues had no detrimental effects on growth
or development in A. caliginosa. This was because scientists
added fresh Bt-corn material to the soil every 28 days;
Bt-protein in corn leaves is degraded with a half-life
of about 20-40 days.
