The evolution of the North American oenotheras of the “biennis” group

Protein Polymorphism and Genic Heterozygosity in a Population of the Permanent Translocation Heterozygote, Oenothera biennis

“…The species best known for permanent structural heterozygosity is the evening primrose Oenothera biennis (12). This species carries two genomes (Renner complexes), which involve seven chromosomes each.…”

Mutational Pressure Drives Evolution of Synonymous Codon Usage in Genetically Distinct Oenothera plastomes

“…Interestingly, high degree of phenotypic variation was observed among members of biennis group across various disjunct populations in different places of North America (29). Thus, small disjunct populations of Oenothera sp.…”

“…All examined plastomes belong to the subsection Euoenothera (biennis group) (29). Interestingly, high degree of phenotypic variation was observed among members of biennis group across various disjunct populations in different places of North America (29).…”

“…The angiosperm genus Oenothera (Family: Onagraceae) is commonly distributed in South Africa (28) and North America (29). Genus Oenothera is considered to be well suited for understanding the various molecular aspects of speciation process as it is amongst well-characterized plant genera (30).…”

Heritability of seed yield, oil concentration and oil quality among wild biotypes of Ontario evening primrose

“…Evening primrose oil (EPO) although it is most frequently found in the is used in various countries to treat atopic easternpartofthecountry (Halletal.1988 (Horrobin 1992 (Steiner 1974),'although the work described here will be restricted to O. biennis. Oenothera biennis exists in two botanical groups (I, tt) in eastern North America (Cleland 1958;Ravin etal. 1979 The trials were grown for 3 yr (1988)(1989)(1990) at the Delhi Research Station on a Fox loamy sand using agronomic practices for evening primrose production similar to those outlined by Sheidow and Roy (1990 Resultant yield, oil and fatty acid data were analyzed using a combined analysis ofvariance, where years and biotypes were considered to be random effects.…”
