PLANT RESEARCH NEWS
A new concept to
engineer specific transcription of transplastomic genes
Silva Lerbs-Mache
Application of plastid transformation technology is limited
by the difficulty of obtaining regulated, selective
expression of the transgenes.
To attempt to solve this problem, a nuclear DNA-encoded and
plastid-targeted T7 phage RNA polymerase gene was introduced
into tobacco and placed under control of a T7 promoter.
However, it turns out that the corresponding protein was not
detectable, and plants grew slowly or died soon after
germination.

REGULATORY NEWS
Legislating agbiotech
Phillip B C Jones
Pew Initiative analysts counted 117 pieces of legislation
related to agricultural biotechnology introduced in 33
states and the District of Columbia during the 2005
legislative session. One of the most active legislative
topics in 2005 also represented a new trend: bills to
preempt or disallow local and county initiatives aimed at
limiting or prohibiting genetically engineered seeds and
crops.

Does the ecological risk
assessment (ERA) process work for GE crops?
Jeff Wolt and Saharah Moon Chapotin
This year marks the unofficial 25th anniversary of the
ecological risk assessment (ERA) process as practiced within
the federal government. The ERA uses a 'framework approach'
that presents a logical scheme for organizing complex
information describing environmental exposure scenarios and
effects to ecological entities of concern. The timeline for
evolution of the regulatory process for safety assessment
for GE crops roughly parallels that for the ERA process.

Mycotoxin reduction in
Bt corn: Potential economic, health, and regulatory impacts
Felicia Wu
Because of reduced pest damage, one indirect benefit of Bt
corn is lower levels of mycotoxin contamination. Bt corn has
been shown to have significantly lower levels of common
mycotoxins. In less developed countries, the mycotoxin
reduction that Bt crops can provide could have important
economic as well as health impacts. Thus, it is an important
phenomenon to consider when developing regulatory policies
on Bt crops.
