International collaborations underpinning the race to plot
the first legume genome, Medicago truncatula (also known
as Barrel medic), were reinforced during a recent workshop at
Rottnest Island.
The Medicago truncatula sequence will provide a
framework for legume genetics to help researchers carve years
off breeding programs and deliver superior varieties to drive,
for example, Australia’s $600 million pulse industry.
It also paves the way to a knowledge-based approach to
produce better legumes.
Officially opening the workshop to an audience of 75
delegates, including key researchers from the United States and
European Union, Chairman of Western Australia's
State Agricultural
Biotechnology Centre (SABC) management committee and former
Western Australia Minister for Commerce and Trade, Hendy Cowan,
welcomed the co-operative effort.
"Globally, research is in progress to sequence all the
genetic information in Medicago truncatula and to compare
it with other legumes to understand how they work on a genetic
level. By applying that knowledge, improvements in crop grain
and forage legumes will occur more rapidly than if working in
isolation on individual crops."
The Medicago truncatula sequence, which should be
complete by 2004, could help inform research into any of the
16,000 known legume species.
Initial goals for legume improvement include pest and disease
resistance, greater nitrogen fixation, enhanced animal and human
nutrition and better plant stature to facilitate efficient
harvesting using conventional cereal harvesters.
Other exciting prospects involve the development of varieties
able to produce human neutraceuticals while withstanding
drought, heat, frost and salinity.
SABC Director, Mike Jones of
Murdoch University,
noted that quickly overcoming cropping constraints through more
efficient breeding would help local farmers tap blossoming high
value human consumption pulse markets in Asia.
"Pulses have up to three times the protein content of
cereals, which makes them an attractive, low-cost food protein
alternative for developing countries and an increasingly popular
health food option in developed nations.
"Legumes are also estimated to add $600 million per annum in
value to Australia’s cereal industry through their rotational
benefits."
The SABC and Murdoch University, major sponsors of the
workshop, in association with the
Grains Research &
Development Corporation, is home to Western Australia’s key
molecular biology and genomics technology and has played a
critical role in attracting world class infrastructure and
expertise to the state.
"Through the SABC, Western Australia now has the
infrastructure and know-how to compete nationally for research
and development funding to support agricultural biotechnology.
Organising the ‘First Australian Medicago truncatula
Workshop’ is evidence of that growing reputation," Professor
Jones observed.
Workshop convenor, Dr Geoff Dwyer of Murdoch University, said
the workshop’s success would set the scene in Australia for
future work on this model legume.
