Issued Jun. 18, 2013. US Patent # 8,465,721B2

Lefebvre, DD and C Edwards. (co-inventors) “Biosynthesis of nanoparticles” This invention provides a method of biosynthesizing nanoparticles and quantum dots with photosynthesizing microorganisms. Nanoparticles, esp.quantum dots which have numerous electrochemical applications, are expensive to synthesize. Therefore a biological way of making them such as presented in this patent has great value for their mass production.

Lefebvre, DD and M Malboobi. (co-inventors) “Phosphate-deficiency inducible promoter” with distinct claims from US Patent 5,922,564 Issued July 13, 1999. Plants in which this promoter induces production of valuable proteins and chemicals for molecular farming applications.

Issued August 1, 2000, US Patent # 6,096,545
Issued June 21, 2001, Australia Patent # 730,471
Issued February 11, 1998, South Africa Patent # 97/6787

Lefebvre, DD and M Malboobi (co-inventors) “Phosphate starvation-inducible proteins”. This patent protects genes that are able to make plants more efficient users of phosphate as a nutrient, allowing less chemical fertilizers to be applied to agricultural lands. They also improve seed nutrient quality by lowering the amount of anti-nutritive phytate, a major impediment for using canola meal for fish production.

Issued November 2, 1999 US Patent # 5,977,435

Lefebvre, DD and KS Gellatly (co-inventors) “Plant Phosphatases” Several phosphatase genes that represent a new family of these enzymes with commercial applications such as meal treatment for anti-nutritive phytate reduction in seeds and enhanced phosphate fertilizer utilization are being protected. Also protected are their effects on phosphate related phenomena in plants such as amount and timing of flowering, and extent of root growth.

Issued December 30, 1998 South Africa Patent # 98/1515 Lefebvre, DD and M Malboobi (co-inventors) “Phosphate-deficiency inducible promoter.” Plants in which this promoter is employed to express genes that improve agronomic traits such as enhanced growth because of better phosphate utilization and tolerance to biotic stress. It is an extremely strong root specific promoter under phosphate limiting conditions with an appreciable level constitutive expression under normal growing conditions.
