The Effects of Flower Color Transitions on Diversification Rates in Morning Glories (Ipomoea subg. Quamoclit, Convolvulaceae)
As in many clades of flowering plants, the Quamoclit clade of morning glories (Ipomoea subgenus Quamoclit) exhibits unequal proportions of different flower colors, with pigmented species outnumbering unpigmented species by nearly a factor of 7. We examined three possible macroevolutionary explanations for this pattern: (1) asymmetric transition rates between pigmented and unpigmented flowers; (...
متن کاملErgot Alkaloids and their Hallucinogenic Potential in Morning Glories.
Naturally occurring and semisynthetic ergot alkaloids play a role in health care or as recreational drugs in Western and indigenous Mexican societies. Evidence is summarized that ergot alkaloids present in Central American Convolvulaceae like Turbina corymbosa, Ipomoea violacea, and Ipomoea asarifolia are colonized by different species of a newly described clavicipitaceous fungal genus named Pe...
متن کاملIdentification of new chalcone synthase genes for flower pigmentation in the Japanese and common morning glories.
New cDNA sequences for chalcone synthase (CHS), a key enzyme in the flavonoid biosynthesis, were obtained from the Japanese and common morning glories; they are more closely related to other CHS sequences than the six previously described CHS genes from the same plants. The newly isolated CHS-D gene is abundantly expressed in the pigmented flower buds, while its expression is drastically reduce...
متن کاملdetermination of maximal singularity free zones in the workspace of parallel manipulator
due to the limiting workspace of parallel manipulator and regarding to finding the trajectory planning of singularity free at workspace is difficult, so finding a best solution that can develop a technique to determine the singularity-free zones in the workspace of parallel manipulators is highly important. in this thesis a simple and new technique are presented to determine the maximal singula...
15 صفحه اولThe evolutionary potential of Baker's weediness traits in the common morning glory, Ipomoea purpurea (Convolvulaceae).
PREMISE OF THE STUDY Many reports have cited Baker's list of weediness traits, or those that exemplify the "ideal" weed, yet few have considered the evolutionary potential of such traits as a group. Thus, it is unknown whether constraints on the evolution of increased weediness, such as a lack of genetic variation or genetic correlations between the traits, are present. Ipomoea purpurea, the co...
