The level of polymorphisms of many biochemical and DNA markers are low in
cultivated sunflower (Helianthus annuus L.). The number of mapped public DNA
markers is limited. Molecular markers have not been developed for the most
important diseases of sunflower, such as downy mildew. The objectives of this
study were...
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...
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...
Cultivated meadowfoam (Limnanthes alba Benth.) is an annual oil seed crop native to southern Oregon. California and British Columbia. The genus Limnanthes is composed of nine species and divided into two sections, Inflexae and Reflexae. The seed oil of meadowfoam is a rich source of erucic acid and several novel...
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...
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...
Cuphea is an herbaceous genus having species whose seed
storage lipids are predominantly medium-chain triglycerides (MCTs).
Cuphea lanceolate Ait, and Cuphea viscosissima Jacq. are central to
the breeding of Cuphea as a new commercial source of MCTs. The
objectives of this thesis were to develop a reliable method to
extract...
