Molecular DNA markers have become widely used in all areas of genetic
research. The objectives of this thesis were to develop polymorphic markers in sunflower
and utilize the markers for genetic and candidate gene analyses. Amplified fragment
length polymorphism (AFLP) markers were used to estimate genetic similarities and
assess the...
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...
Cuphea laminuligera Koehne and Cuphea lutea Rose in Koehne are
undomesticated species having potential as oilseed crops. Genetic
markers and mating systems have not been described for these
species. Our objectives were to survey these species for allozyme
variation, analyze the segregation and linkage of polymorphic loci,
estimate autofertility and...
Fiber flax (Linum usitatissimum L.) production in the Willamette Valley ended in
Oregon around 1957 before newly developed technology and fiber cultivars were
available. The purpose of this research was to explore the use of modern methods and
new cultivars.
Field studies were conducted to evaluate cultivars and optimum cultural...
The cultivated sunflower (Helianthus annuus L., x=17) is one of the most important annual oilseed crops in the world. There are very few publicly shared sequence-based DNA markers and genetic maps in sunflower, even though molecular DNA markers and genetic maps have become widely used in all areas of genetic...
Marker information in the new oilseed crop, meadowfoam, is limited. Molecular markers to facilitate meadowfoam breeding and cultivar improvement are not available. The knowledge of genetic relationships among recent germplasm is not known. The objectives of this study were (i) to gain an understanding of genetic diversity and relationship patterns...
