Whole-Plant Mineral Partitioning Throughout The Life Cycle In Arabidopsis Thaliana Ecotypes Columbia, Landsberg Erecta, Cape Verde Islands, And The Mutant Line Ysl1ysl3, Brian M. Waters, Michael A. Grusak

Department of Agronomy and Horticulture: Faculty Publications

Minimal information exists on whole-plant dynamics of mineral flow through Arabidopsis thaliana or on the source tissues responsible for mineral export to developing seeds. Understanding these phenomena in a model plant could help in the development of nutritionally enhanced crop cultivars. A whole-plant partitioning study, using sequential harvests, was conducted to characterize growth and mineral concentrations and contents of rosettes, cauline leaves, stems, immature fruit, mature fruit hulls, and seeds of three WT lines (Col-0, Ler, and Cvi) and one mutant line (Col-0::ysl1ysl3). Shoot mineral content increased throughout the life cycle for all minerals, although tissue-specific …

Australian Temperate Strawberry Breeding Program (Western Australia) Selection Of New And Advanced Short Day Breeding Lines And Cultivars In Western Australia - 2006/2007, Aileen Reid, Dennis Phillips, Hal

Horticulture research reports

Thirty-two ‘Stage 4’ numbered selections (2004 crosses) from the Australian Temperate Strawberry Breeding Program were evaluated in unreplicated plots on a commercial property in Wanneroo for their potential under WA conditions. Seven of these have been selected as worthy of further testing. The priority selection among these was 04- 021-263, and the other six included 04-021-467, 04-037-102, 04-021-241, 04-021-172, 04-021-475 and 04-029-211.

In addition, 21 advanced numbered selections (Stages 5, 6 and 7) were also evaluated on the same grower’s property. Three of those were substantially larger plots and a later planting date. Of the first group of 18 selections, …

Impacts Of Genetic Bottlenecks On Soybean Genome Diversity, D. L. Hyten, Qijian Song, Youlin Zhu, Ik-Young Choi, Randall L. Nelson, Jose M. Costa, James E. Specht, Randy C. Shoemaker, Perry B. Cregan

Department of Agronomy and Horticulture: Faculty Publications

Soybean has undergone several genetic bottlenecks. These include domestication in Asia to produce numerous Asian landraces, introduction of relatively few landraces to North America, and then selective breeding over the past 75 years. It is presumed that these three human-mediated events have reduced genetic diversity. We sequenced 111 fragments from 102 genes in four soybean populations representing the populations before and after genetic bottlenecks. We show that soybean has lost many rare sequence variants and has undergone numerous allele frequency changes throughout its history. Although soybean genetic diversity has been eroded by human selection after domestication, it is notable that …

Restoration Of Aspen Woodland Invaded By Western Juniper: Applications Of Partial Cutting And Prescribed Fire, Jonathon D. Bates, Richard F. Miller

Aspen Bibliography

Western juniper (Juniperus occidentalis spp. occidentalis) woodlands are rapidly replacing quaking aspen (Populus tremuloides) stands throughout the northern Great Basin. Aspen stands provide important habitat for many wildlife species and contain a high diversity of understory shrubs and herbaceous species. We studies two juniper removal treatments to restore aspen woodlands in Kiger Canyon on Steens Mountain, Oregon.

Registration Of N547 Maize Germplasm Line, Nora E. D'Croz-Mason, John E. Foster, Stephen C. Mason

Department of Entomology: Faculty Publications

N547 germplasm line (Reg. no. GP-367, PI 615526) was released by the Agriculture Research Division, Institute of Agriculture and Natural Resources, University of Nebraska, on 24 Aug. 1999. N547 is a yellow endosperm maize inbred germplasm with resistance to stalk and shank tunneling damage caused by the second generation of the European corn borer (ECB) Ostrinia nubilalis (Hubner).

N547 was derived by selfing a selected full-sib family from MBITA, a tropical population developed by CIMMYT, Mexico. MBITA was created to recombine sources of resistance to temperate and subtropical stalk borers. These insects included ECB, southwestern corn borer (SWCB) Diatraea grandiosella …

Achievements In Wool 1997, Agriculture Western Australia

Animal production and livestock published reports

The Wool Strategy Group, which I initiated in 1993, and Agriculture Western Australia's Wool Program are strategic partners working together with industry to develop and market this State's wool industry.

Wool is Western Australia's second most important agricultural industry, with a current export value of $643 million. It has the potential to return to a billion dollar industry in the next five years and the industry needs to be strongly focused on producing what the market requires to take advantage of this.

The Wool Strategy Group, led by Chairman Mr Philip Gardiner, and the Wool Program, have established an international …

Fire-Bgc--A Mechanistic Ecological Process Model For Simulating Fire Succession On Coniferous Forest Landscapes Of The Northern Rocky Mountains, Robert E. Keane, Penelope Morgan, Steven W. Running

Aspen Bibliography

An ecological process model of vegetation dynamics mechanistically simulates long-term stand dynamics on coniferous landscapes of the Northern Rocky Mountains. This model is used to investigate and evaluate cumulative effects of various fire regimes, including prescribed burning and fire exclusion, on the vegetation and fuel complex of a simulation landscape composed of many stands. Detailed documentation of the model FIRE-BGC (a FIRE BioGeoChemical succession model) with complete discussion of all model parameters is followed with results of an application of the FIRE-BGC to a whitebark pine landscape in the Bob Marshall Wilderness Complex. Simulation results of several management scenarios are …

Waste-Wood-Derived Fillers For Plastics, Brent English, Craig M. Clemons, Nicole Stark, James P. Schneider

Aspen Bibliography

Filled thermoplastic composites are stiffer, stronger, and more dimensionally stable than their unfilled counterparts. Such thermoplastics are usually provided to the end-user as a precompounded, pelletized feedstock. Typical reinforcing fillers are inorganic materials like talc or fiberglass, but materials derived from waste wood, such as wood flour and recycled paper fiber, are also effective as fillers. The goal of this project was to generate commercial interest in using waste-wood–paper-derived fillers (WPFs) to reinforce thermoplastics. The research strategy was twofold: developmental research and outreach. Specific objectives were (1) to improve wastepaper fiber preparation, feeding, and compounding methods, and optimize composite performance, …

Plant Community Changes Over 54 Years Within The Great Basin Experimental Range, Manti-La Sal National Forest, Scott C. Walker, David K. Mann, E. Durant Mcarthur

Aspen Bibliography

Plant community changes and natural succession over time impact forage values, watershed quality, wildlife habitat, and ecosystem dynamics. Comparisons were made between a vegetation map of community types completed in 1937 by the U.S. Forest Service, and vegetation maps compiled in 1990 of the same areas by satellite imagery, and through 1991 areal photo interpretation combined with ground truthing. The study area includes nearly all of the drainage in Ephraim Canyon located in central Utah which consists of 6,027 acres (2,439 ha). Elevation ranges from 6,600 to 10,400 feet (2,040 to 3,210 m). Vegetation types ranged from pinyon-juniper woodland through …
