not an agricultural crop - it's a wild
tree that needs our help."
While the young trees grow,
Powell and his team continue their
research. They have developed
a field test that indicates, within
four hours, which nuts contain
the blight resistance gene and
which do not. They are collecting
data about whether leaf litter from
transgenic American chestnuts
on the forest floor affects the
germination rate of other tree
species and whether leaf litter in

streams had any adverse effect
on aquatic insects. They are also
studying whether the transgenic
trees have any negative impact on
the beneficial mycorrhizal fungi that
typically colonize the root system
of host plants.
"We've done enough research
to know that the transgenic trees
have no detrimental effects on leaf
litter, insects or fungi," Powell says.
"But we're doing further studies
to build a body of knowledge that
shows these trees will not harm the
environment in any way."
ESF is speeding up the
production of transgenic trees at a
recently launched Tissue Culture
Production Lab at the Biotech

Accelerator in Syracuse. There,
young plants grown from tissue
cultures are nurtured until they can
be transplanted and eventually
moved outdoors as the seed
orchard expands over the next
two years.
The next long-term goal is to
obtain funding for a "century study"
that would allow researchers
to establish a couple 120-acre
research sites to conduct a longterm comparison between wildtype, transgenic, back-crossed and
hybrid American chestnuts. Powell
expects the regulatory process
will be complete before any of
those trees began to pollinate and
reproduce on their own.
