DC atmospheric pressure glow microdischarges in the current range from microamps up to amperes

Electrical and spectroscopic results of comprehensive investigations of microdischarges in atmospheric pressure helium, argon, nitrogen and air at gaps less than 1 mm and over a large current range from microamperes up to amperes are presented. At distance shorter than 1 mm, electrodes influence the normal glow discharge structure and their electrical and optical parameters. Two oscillation discharge regimes were revealed in discharge current range comparable or less than the low-current limit of normal glow discharge

Development Of Molecular Markers In Redbay

Woody plant redbay (Persea borbonia) is a native species in South Carolina whose fine-grained wood is industrially valuable and whose fruits are a valuable food source for animals. However, laurel wilt disease has caused high levels of redbay death, threatening the sustainability of this economically and ecologically important woody plant species. Planting resistant clones of trees is the most promising approach to combat the disease. Large-scale development of molecular markers is imperative in molecular breeding for crop improvement. This project aimed to initiate a small-scale analysis of approximately 200 markers obtained from a shallow genome sequencing project of redbay. The markers that were being used targeted microsatellites, small tandem repeats of DNA that are highly mutable. Of the 213 markers being tested, polymerase chain reaction (PCR) amplification success rate was 94% among the 8 individuals that were used. A total of 160 markers had amplicons that were at least 100 base pairs in length. When fully characterized, these markers will be valuable in linkage map construction, molecular characterization of germplasm collections, and analysis of genetic diversity in redbay
