Use Of Hrma Proteins And Their Genes For Broad Range Protection Of Plants Against Bacterial, Fungal And Viral Pathogens, Qingshun Li, Songhai Shen, Arthur G. Hunt

Kentucky Tobacco Research and Development Center Faculty Patents

The use of an avr gene hrmA to induce systematic acquired resistance in plant cells, plant seeds, plant tissues and plants is disclosed. Also disclosed is the use of low level expression of promoters in combination with the hrmA gene to provide broad-spectrum pathogen resistance in plant cells, plant seeds, plant tissues and plants.

Materials And Methods Useful To Affect Growth And Development Of Lepidoptera Larvae, Douglas Lee Dahlman, Bruce Allen Webb, Indu B. Maiti

Kentucky Tobacco Research and Development Center Faculty Patents

The present invention provides materials and methods related to causing insect resistance in plants. Specifically, the present invention provides nucleic acid compounds which encode a teratocyte secreted protein (TSP) which is capable of causing inhibition of growth and developmental arrest in Lepidoptera larvae. Cells and plants (including plant parts, seeds, embryos, etc.) comprising the nucleic acid compounds are also within the scope of the present invention. The present invention also provides amino acid compounds encoded by the nucleic acid compounds of the present invention, as well as methods to induce larval developmental arrest, methods to produce the nucleic acid and …

Endophyte Ergot Alkaloid Synthetic Compounds, Compounds Which Encode Therefor And Related Methods, Christopher L. Schardl, Jinhung Wang

Plant Pathology Faculty Patents

The present invention provides, inter alia, dmaW nucleic acid sequences and the proteins for which they encode. Also provided are methods for the utilization of knockout mutants of the sequences which are useful for engineering ergot alkaloid-deficient fungal symbionts (endophytes) of plants. Other methods and materials related to these sequences are also provided.

Stripping Burley Tobacco Into Grades, Gary K. Palmer

Agronomy Notes

Stripping burley tobacco into different grades has been a controversial topic for many years. The one-price years in the mid to late 80’s provided no incentive to the producer to strip into the appropriate grades. However, with the advent of contracting in the year 2000, many companies are suggesting four grades but still get a high percentage of three-grade tobacco. Tobacco companies can utilize a small percentage of mixed stripped tobacco, but the handling characteristics of the four stalk positions differ substantially during processing. As the companies make their blends, they look for specific characteristics that differ from grade to …

Phosphorus Soil Test Change Following The Addition Of Phosphorus Fertilizer To 16 Kentucky Soils, William O. Thom, James E. Dollarhide

Agronomy Notes

When applying phosphorus to soils it is important to know how much the soil test P changes with the addition of various rates. Soils are different in how they respond to varying rates of application, and only limited information is available for Kentucky soils.

Genetic Variation For Fusarium Head Blight Resistance In Soft Red Winter Wheat, Marla Dale Hall

University of Kentucky Master's Theses

Fusarium graminearum, the causative agent of Fusarium head blight, is an economically important pathogen of wheat (Triticum aestivum). Breeding Fusarium head blight (FHB) resistant wheat requires knowledge of the underlying genetic control of FHB resistance.

Two nine-parent diallel analyses were completed in greenhouse and field environments. Combining abilities, variance component ratios, and narrow sense heritabilities for FHB resistance and deoxynivalenol levels were calculated. Significant general and specific combining ability effects were observed. Resistance to FHB seems to be mostly controlled by additive genetic effects with some dominance noted in the field. Resistance noted in the greenhouse environment …

Fiber Optic Sensor Response To High Levels Of Fat In Cream, Czarena L. Crofcheck, Frederick A. Payne, Clair L. Hicks, M. Pinar Mengüç, Sue E. Nokes

Biosystems and Agricultural Engineering Faculty Publications

A light backscatter technique using optical fibers to deliver and receive light was investigated for measuring the milkfat content of unhomogenized cream. Light backscatter through cream at wavelengths of 450 to 900 nm was measured for fiber separation distances from 2 to 6.5 mm and for cream containing 10 to ~40 weight percent (wt%) milkfat. Unhomogenized cream (~40 wt% milkfat) was mixed with skim milk (~0.05 wt% milkfat) to yield samples with five different milkfat levels. Three optical response models were tested for correlation with milkfat content: one using the light intensity measurement at a single separation distance, the second …

KWRRI Annual Technical Reports (USGS’s 104b Grant Program)

The FY 2001 Annual Technical Report for Kentucky consolidates reporting requirements of the Section 104(b) base grant award in a single technical report that includes: 1) a synopsis of each research project supported during the period, 2) a list of related reports, 3) a description of information transfer activities, 4) a summary of student support during the reporting period, and 5) notable achievements and awards during the year.

“Burn Down” Management Of Winter Cereal Cover Crops For No-Tillage Burley Tobacco Production, Robert C. Pearce, David C. Ditsch, Jack M. Zeleznik, Wade Turner

Agronomy Notes

Recent developments in the design of no-till transplanters and significant improvements in weed control have made no-till tobacco production a feasible option for burley tobacco growers. No-till production reduces soil erosion when tobacco is grown on sloping land. This helps maintain the long term productivity of the soil and may provide the grower with more options for crop rotation, by allowing sloping land to be utilized for tobacco production.
