Engineered plants make potential precursor to raw material for plastics
Date:11/8/2010

ined the most promising traits into a single new plant.

The result was an accumulation of the desired omega-7 fatty acid at levels of about 71 percent in the best-engineered line of Arabidopsis. This was much higher than the omega-7 fatty acid levels in milkweed, and equivalent to those seen in cats claw vine. Growth and development of the engineered Arabidopsis plants was unaffected by the genetic modifications and accumulation of omega-7 fatty acid.

This proof-of-principle experiment is a successful demonstration of a general strategy for metabolically engineering the sustainable production of omega-7 fatty acids as an industrial feedstock source from plants, Shanklin said.

This general approach identifying and expressing natural or synthetic enzymes, quantifying incremental improvements resulting from additional genetic/metabolic modifications, and stacking of traits may also be fruitful for improving production of a wide range of other unusual fatty acids in plant seeds.
