Protein polymorphism and genic heterozygosity in a population of the permanent translocation heterozygote, Oenothera biennis.
Genic allozyme polymorphism and heterozygosity was studied in a large population of the evening primrose, Oenothera biennis, growing in North Haven, Connecticut. This species is a permanent structural heterozygote for the entire complement of 14 chromosomes, and is thus capable of accumulating and maintaining genic heterozygosity. A total of 11 protein species were examined, and these were judg...
متن کاملTaxonomic changes in Oenothera sections Gaura and Calylophus (Onagraceae)
The long-recognized genus Gaura was shown recently to be deeply nested within one of two major clades of Oenothera. New molecular data indicate further taxonomic changes are necessary in Oenothera sect. Gaura. We make these changes here, including three new combinations, in advance of the Onagraceae treatment for the Flora of North America. The new phylogenetic studies show that several pairs o...
متن کاملThe correct name in Oenothera for Gaura drummondii (Onagraceae)
In 2007, Wagner and Hoch proposed the new name Oenotheraxenogaura W.L.Wagner & Hoch for the species then known as Gauradrummondii (Spach) Torrey & A. Gray (non Oenotheradrummondii Hooker, 1834). However, the authors overlooked the availability of Gaurahispida Bentham (1840) for this species. Accordingly, we herewith make the appropriate new combination for this species, Oenotherahispida (Bentha...
متن کاملGenic Heterozygosity and Variation in Permanent Translocation Heterozygotes of the OENOTHERA BIENNIS Complex.
Genic heterozygosity and variation were studied in the permanent translocation heterozygotes Oenothera biennis I, Oe. biennis II, Oe. biennis III, Oe. strigosa, Oe. parviflora I, Oe. parviflora II, and in the related bivalent formers Oe. argillicola and Oe. hookeri. From variation at 20 enzyme loci, we find that translocation heterozygosity for the entire chromosome complex is accompanied by on...
متن کاملAnti-Melanogenic Effect of Oenothera laciniata Methanol Extract in Melan-a Cells
We evaluated the antioxidant activity and anti-melanogenic effects of Oenothera laciniata methanol extract (OLME) in vitro by using melan-a cells. The total polyphenol and flavonoid content of OLME was 66.3 and 19.0 mg/g, respectively. The electron-donating ability, 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) radical-scavenging activity, and superoxide dismutase (SOD)-like act...
