Gag Proteins Of The Two Drosophila Telomeric Retrotransposons Are Targeted To Chromosome Ends, Svetlana Rashkova, Sarah E. Karam, Rebecca Kellum, Mary-Lou Pardue

Biology Faculty Publications

Drosophila telomeres are formed by two non-LTR retrotransposons, HeT-A and TART, which transpose only to chromosome ends. Successive transpositions of these telomeric elements yield arrays that are functionally equivalent to the arrays generated by telomerase in other organisms. In contrast, other Drosophila non-LTR retrotransposons transpose widely through gene-rich regions, but not to ends. The two telomeric elements encode very similar Gag proteins, suggesting that Gag may be involved in their unique targeting to chromosome ends. To test the intrinsic potential of these Gag proteins for targeting, we tagged the coding sequences with sequence of GFP and expressed the constructs …

Mechanical Properties Of Corn And Soybean Meal, Marek Molenda, Michael D. Montross, Jozef Horabik, Ira Joseph Ross

Biosystems and Agricultural Engineering Faculty Publications

Ground corn and soybean meal are common ingredients in feed mixes. The knowledge of their mechanical properties is important to the feed manufacturer and consumer.

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 …
