The LMO carries the introduced genetic modification in the plastids
exclusively. Accordingly, it is though that the genetic
modification is not transferred to offspring by paternal but solely
by maternal inheritance. Within the described field trial it is
meant to test whether vertical gene transfer of the genetic
modification occurs nevertheless. Therefore, the transplastomic
tobacco plants are cultivated together with non-modified,
male-sterile plants. The seeds of the non-modified plants will be
grown and analyzed for resistance towards streptromycin and
spectomycin and for GFP expression. By means of this field trial it
is meant to test whether the described system is suitable as a
confinement system for the development of LMO. The rate of paternal
inheritance of plastids (paternal leakage) and of gene transfer
from the plastome to the nuclear genome of the tobacco plants under
cultivation conditions - including different climatic and soil
conditions - is analyzed.
