Phylogenetics in Clarkia (Onagraceae): Restriction Site Mapping of Chloroplast DNA
Restriction site maps of chloroplast DNA (cpDNA), maternally inherited in Clarkia, were obtained in representative species of all seven diploid sections, the allotetraploid sect. Clarkia, and the outgroup Epilobium brachycarpum. CpDNA restriction site variation was analyzed by Wagner and Dollo parsimony, bootstrapping, and genetic distance methods. Four shortest Wagner trees, one of which was a...
متن کاملChloroplast DNA evidence for the origin of the genus Heterogaura from a species of Clarkia (Onagraceae).
Restriction-site variation in chloroplast DNA was examined in the morphologically distinct and monotypic genus Heterogaura and the related speciose genus Clarkia (Onagraceae), both native to California. Of the 605 restriction sites surveyed, a total of 119 mutations were identified. Of these, 55 were shared by at least two species and were used to construct a most parsimonious phylogenetic tree...
متن کاملthe effect of e-64 on the developmental competence of sheep cocs during in vitro maturation
in the present study, the effect of e-64 at different concentrations (0.5, 1, 5 and 10 µm) added to (1) the ivm medium on oocyte nuclear maturation and developmental competence of ovine oocytes, and (2) to the ivc medium on embryonic development of ovine embryos were investigated.
Precise spatio-temporal regulation of the anthocyanin biosynthetic pathway leads to petal spot formation in Clarkia gracilis (Onagraceae).
Petal spots are widespread in angiosperms and are often implicated in pollinator attraction. Clarkia gracilis petals each have a single red-purple spot that contrasts against a pink background. The position and presence of spots in C. gracilis are determined by the epistatic interaction of alleles at two as yet unidentified loci. We used HPLC to identify the different pigments produced in the p...
متن کاملFormation of monoterpenes in Antirrhinum majus and Clarkia breweri flowers involves heterodimeric geranyl diphosphate synthases.
The precursor of all monoterpenes is the C10 acyclic intermediate geranyl diphosphate (GPP), which is formed from the C5 compounds isopentenyl diphosphate and dimethylallyl diphosphate by GPP synthase (GPPS). We have discovered that Antirrhinum majus (snapdragon) and Clarkia breweri, two species whose floral scent is rich in monoterpenes, both possess a heterodimeric GPPS like that previously r...
