The genetic basis of a flower color polymorphism in the common morning glory (Ipomoea purpurea).
The common morning glory (Ipomoea purpurea) is highly polymorphic for flower color. Part of this phenotypic variation is due to allelic variation at the P locus. This locus determines whether flowers will be purple or pink, where purple is dominant to pink. We have determined that the anthocyanin biosynthetic gene flavonoid 3'-hydroxylase (f3'h) corresponds to the P locus. In the pink allele of...
متن کاملThe 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...
متن کاملDynamics of mobile element activity in chalcone synthase loci in the common morning glory (Ipomoea purpurea).
Mobile element dynamics in seven alleles of the chalcone synthase D locus (CHS-D) of the common morning glory (Ipomoea purpurea) are analyzed in the context of synonymous nucleotide sequence distances for CHS-D exons. By using a nucleotide sequence of CHS-D from the sister species Ipomoea nil (Japanese morning glory [Johzuka-Hisatomi, Y., Hoshino, A., Mori, T., Habu, Y. & Iida, S. (1999) Genes ...
متن کاملGenetic Constraints and Selection Acting on Tolerance to Herbivory in the Common Morning Glory Ipomoea purpurea.
Tolerance to herbivory minimizes the effects of herbivory on plant fitness. In the presence of herbivores, maximal levels of tolerance may be expected to evolve. In many plant species, however, tolerance is found at an intermediate level. Tolerance may be prevented from evolving to a maximal level by genetic constraints or stabilizing selection. We report on a field study of Ipomoea purpurea, t...
متن کاملThe Role of Inbreeding Depression in Maintaining the Mixed Mating System of the Common Morning Glory, Ipomoea Purpurea.
Theoretical studies show that, although inbreeding depression (ID) will counterbalance the transmission advantage of selfing, it can only maintain a mixed mating system in plants when at least one of the following two conditions is met: (1) there is a positive association between selfing rates and the level of ID; and (2) ID is greater than 0.5 for the female component of fitness, while the ave...
