The Rural Voice, 1999-03, Page 31bookmarks, in effect. Although they
won't clearly identify the
transformation of the resistant gene
itself, markers will help researchers
identify the transfer of genetic
material from the bacterium to the
corn plant. That's why, said Pauls,
the work on the transformation
system was the primary focus. In the
last year, they've developed the
tissue culture systems that are the
targets for the transformation and
completed co -cultivation experiments
to test for gene transfer.
"We're at the point that I think we
can say we have had the transfer of
the gene from the agrobacterium to
the corn tissue," explained Pauls.
"What we don't have at this point is a
complete plant regenerated from
those corn tissues that is transgenic."
The University's research can
also be applied to various
genotypes; the particle gun
technology used in Ottawa can only
be applied to one genotype at a time.
Still, the research being done in
Ottawa is of equal importance,
according to Pauls; it gives
researchers more diversity for
different aspects of Fusarium
resistance. For one, AAFC's ECORC
is looking at developing a gene that
can neutralize the mycotixin created
by Fusarium.
If it can be transformed, cells in a
corn plant will be resistant to
deoxynivalenol toxin, also known as
DON or vomitoxin. Jas Singh, leader
of Molecular Technology Studies
with ECORC, reported that field tests
will be conducted this coming spring
to determine DON toxin resistance in
several lines of corn plants. The plan
is to replace the DON -sensitive genes
within the corn plant with DON -
resistant ones, inhibiting fungal
growth within the plant. It will be an
important step in the battle against
Fusarium – and could help the wheat
and barley industries as well.
"This gene is a very common
gene," said Singh, noting it's a part
of all living cells. "So if it works for
corn, theoretically, it should work for
wheat, too."
Singh did admit, however, that it's
much easier to introduce the gene
into corn than into wheat or barley.
And that should take some of the
fear out of the word Fusarium — for
everyone.°
