Emerging Research Techniques & New Instrumentation For Plant Biology, Bruce Bugbee
Techniques and Instruments
We have not achieved an efficient food production system in US Agriculture by manipulating only the environment.
Genetic engineering techniques now allow us to quickly develop new crop cultivars.

The Bureau of Land Management (BLM), United States Department of the Interior (USDI), is proposing a program to treat vegetation on up to six million acres of public lands annually in 17 western states in the continental United States (US) and Alaska. As part of this program, the BLM is proposing the use of ten herbicide active ingredients (a.i.) to control invasive plants and noxious weeds on approximately one million of the six million acres proposed for treatment. The BLM and its contractor, ENSR, are preparing a Vegetation Treatments Programmatic Environmental Impact Statement (EIS) to evaluate this and other proposed …

Identification Of Key Genes Required For Abiotic Stress Response In Arabidopsis Thaliana, Saori Endo
Identification Of Key Genes Required For Abiotic Stress Response In Arabidopsis Thaliana, Saori Endo
Undergraduate Honors Capstone Projects
To identify key genes that are required for stress response, a reverse genetics approach was taken to manipulate expression of candidate genes in plants. In this project, two potential regulatory genes which were originally identified as stress-responsive genes from a microarray experiment in Arabidopsis were examined for their roles in stress tolerance. Over-expression of gene A, which was up-regulated under stress conditions based on the array data, caused earlier flowering and improved plant growth under salinity and dehydration stress conditions at the seedling stage. Over-expression of gene B, which was down-regulated under stress conditions based on the array data, resulted …
Changing The Integration Time Has A Minimal Effect On The Accuracy Of The Apogee / Stellarnet Spectroradiometer, Nick Knighton, Bruce Bugbee
Changing The Integration Time Has A Minimal Effect On The Accuracy Of The Apogee / Stellarnet Spectroradiometer, Nick Knighton, Bruce Bugbee
Techniques and Instruments
Changing the integration time has the potential to change the accuracy of the Apogee/StellarNet spectroradiometer. All Apogee/StellarNet spectroradiometers are calibrated to an NIST traceable calibration lamp. This lamp (LI-COR Inc., model 1800-02; Lincoln, NE) has an output of 206.2 µmol m-2 s-1, which requires a relatively long integration time (about 500 ms) to obtain a full scale response. Sunlight and high-wattage electric light sources often have a much higher intensity, which require much shorter integration times (10 to100 ms) to prevent light saturation of the detectors. The accuracy might be affected differently by increasing or decreasing integration …
A Mixture Of Barium Sulfate And White Paint Is A Low-Cost Substitute Reflectance Standard For Spectralon®, Nick Knighton, Bruce Bugbee
A Mixture Of Barium Sulfate And White Paint Is A Low-Cost Substitute Reflectance Standard For Spectralon®, Nick Knighton, Bruce Bugbee
Techniques and Instruments
Barium sulfate is a white powder that has historically been used as a reference standard (Weidner and Hsia, 1981). It may be a less expensive alternative to higher priced white standards that use sintered PTFE (polytetrafluoroethylene; Spectralon®, Labsphere, Inc., North Sutton, NH). A 500 g bottle of BaSO4 costs $25, whereas reflectance standard made of Spectralon® and with a 99% reflectance factor costs $385. However, pure barium sulfate dries to a powder and easily rubs off surfaces. We sought to increase the durability of barium sulfate by mixing it with untinted white latex paint. Reflectance and durability of different ratios …

Spectrometer Curve Smoothing Using Replicate Scans And Running Averages, Nick Knighton, Bruce Bugbee
Techniques and Instruments
The Boxcar Pixel Smoothing algorithm significantly reduced noise in spectral traces. However, averaging replicate scans did not significantly reduce noise in these studies.
Cooperation And Coordination Are Invasive Species: Important For Effective Management Of Invasive Weeds, U.S. Government Accountability Office
Cooperation And Coordination Are Invasive Species: Important For Effective Management Of Invasive Weeds, U.S. Government Accountability Office
All U.S. Government Documents (Utah Regional Depository)
Invasive weeds, native or nonnative plant species, cause harm to natural areas such as rangelands or wildlife habitat and economic impacts due to lost productivity of these areas. While the federal investment in combating invasive species is substantial most has been concentrated on agricultural lands, not on natural areas. In this report, GAO describes (1) the entities that address invasive weeds in natural areas and the funding sources they use; (2) federal, state, and local weed management officials’ views on the barriers to weed management; and (3) their opinions about how additional resources for weed management could be distributed. GAO …
