It took nearly 20 years for
researchers to develop the first commercial genetically enhanced
corn hybrids. The next generation of genetic technology may be
developed in less than half that time.
“Mini-chromosome stacking” uses the plant’s DNA to
simultaneously introduce multiple genetic traits into plants,
reducing the time and cost required to develop and launch new
products. The technology has several advantages over current
genetic technology, says Nathan Fields, the
National Corn Growers Association
(NCGA) director of Research and Business Development.
“There’s no interference with the plant’s native genome, so the
new traits can be delivered more precisely, with increased
ability to regulate trait expression,” explains Fields. “Also,
the technique makes it easier to identify a genetically modified
trait.”
The mini-chromosome technology was developed at the University
of Chicago. Chromatin Inc.
is the exclusive licensee. Earlier this year, it was awarded a
patent granting it exclusive rights for the mini-chromosome
technology in plants. NCGA has been working with Chromatin to
help develop the technology for agriculture and made an
investment in the company in 2004.
This week Monsanto signed
a non-exclusive agreement to use the technology in corn and
other crops. Monsanto and Chromatin will conduct a three-year
program to complete development of the technology.
Chromatin estimates that mini-chromosome technology could
accelerate the timeline from research to commercial introduction
for plants modified with a single trait by two to three years
(25 percent to 40 percent). “The technology offers the chance
for more reliable trait development because the new traits would
be separate,” says Fields. “For the same reason, researchers may
be able to speed up the development and introduction of new
traits.”
