2011 Annual Report
1a.Objectives (from AD-416)
We will investigate the genetic and biochemical regulation of rubber biosynthesis in rubber-producing species, including, but not limited to, Russian Dandelion, Guayule and the Brazilian and Indian Rubber Trees.
1b.Approach (from AD-416)
The collaboration will include measurement of rubber transferase enzyme activity, studies of natural and synthetic (analog) initiators, and interspecific comparisons. This agreement is put into place partially to cover transfer of materials (MTA) including plants, plant tissues, plasmids, isotopes, isoprenoid substrates, chmicals, latex and purified rubber particles, antibodies to latex proteins. It also covers the collaborative work being performed on all the materials transferred.
Documents NFCA with Ohio State University.
In FY2011 a process for removal of protein from Hevea rubber yielded % gel content equivalent to that of guayule rubber but maintained good thermo-oxidative stability. Bulk rheological properties best discriminated the effect of the process on the dried polymers. In addition, a series of materials were transferred to the Ohio State collaborators related to the joint research. The ADODR communicated research and jointly reviewed results through frequent emails and telephone calls, and three in-person meetings in FY2011.
