Wildtype sunflower typically produces 12-24% oleic acid (18:1) and 70-82%
linoleic acid (18:2). High-oleic sunflower, by contrast, produces up to 80-94% oleic
acid. The monounsaturated oleic acid has a greater oxidative stability than the
polyunsaturated linoleic acid, predominant in wildtype sunflower, and has greater
nutritional benefits than polyunsaturated and saturated...
Single nucleotide polymorphisms (SNPs) are the most common DNA polymorphisms in plant and animal genomes. SNPs were identified in the allele sequences of up to 12 sunflower (Helianthus annuus L.) genotypes for a genome-wide sample of 81 loci originally mapped using restriction fragment length polymorphism (RFLP) markers. The RFLP loci...
Microsatellites or simple sequence repeats (SSRs) are highthroughput sequence based DNA markers that have been exploited as tools for measuring genetic distance and diversity in evolutionary studies, protection of intellectual property, genetic resource conservation management, cultivar identification and molecular breeding of crop plants. We isolated and sequenced 1095 clones from...
Medium chain fatty acids (MCFAs) are important industrial feedstocks for
soaps, detergents and surfactants. Interspecific lines derived from Cuphea lanceolata
and Cup hea viscosissima are being domesticated as a temperate source of MCFAs.
These species also serve as model organisms for understanding the biosynthesis of
MCFAs in seeds. Various markers...
The intensification of cyclonic winds in the Gulf of Alaska
during winter belies the relatively constant geostrophic circulation
as being indicative of actual flow. In the absence of direct current
measurements, effects of various meteorological phenomena have
been eliminated from monthly mean sea level measurements over the
decade 1950 to...
Tocopherols are plant secondary metabolites that are known collectively as
vitamin E. Tocopherol compounds act as potent antioxidants by quenching free
radicals and protecting fatty acids from oxidative damage. In humans (in vivo)
tocopherols protect membrane lipids from breaking down, while in oils (in vitro)
tocopherols protect fatty acids from...
This thesis examines the multi-faceted threat Iran poses to the stability of the Middle Eastern region, to U.S. geopolitical interests and to the furthering of democratic principles from a realist perspective. Iran’s failure to negotiate a nuclear accord in good faith coupled with its continued militant role in regional affairs...
Back pain is the leading cause of disability worldwide, entailing a significant socioeconomic impact. A primary source of back pain can be attributed to intervertebral disc (IVD) degeneration allowing nerve ingrowth, facet joint arthritis, disc bulging, and osteophyte formations that press on nearby nerve roots or the spinal cord. While...
