Fitness costs of herbicide resistance across natural populations of the common 1 morning glory
18 Although fitness costs associated with plant defensive traits are widely expected, they are 19 not universally detected, calling into question their generality. Here we examine the 20 potential for life history trade-offs associated with herbicide resistance by examining seed 21 germination, root growth, and above-ground growth across 43 naturally occurring 22 populations of Ipomoea purpurea...
متن کاملMorning glory syndrome.
Morning glory syndrome is a congenital optic disc anomaly in which much of the excavated colobomatous optic disc is filled with glial tissue. Ocular complications may include strabismus, reduced visual acuity and retinal detachment and it may have systemic associations as in Aicardi's syndrome. A patient with monocular morning glory syndrome and reduced visual acuity is reported. The pattern re...
متن کاملConstraints on the evolution of tolerance to herbicide in the common morning glory: resistance and tolerance are mutually exclusive.
Evolutionary biologists explain the maintenance of intermediate levels of defense in plant populations as being due to trade-offs, or negative genetic covariances among ecologically important traits. Attempts at detecting trade-offs as constraints on the evolution of defense have not always been successful, leading some to conclude that such trade-offs rarely explain current levels of defense i...
متن کاملPatient with Morning Glory syndrome
A 6-year-old patient was referred to our ophthalmology service because of an ocular deviation (esotropia) on the right eye for 3 years. Best-corrected visual acuity in right eye and 20/20 in left eye. According to the Krimsky test, the patient showed 15 prism dioptres esotropia in right eye. No changes were observed in biomicroscopy of both eyes and funduscopy of left eye was normal. An optical...
متن کاملGenetics of Resistance to the Rust Fungus Coleosporium ipomoeae in Three Species of Morning Glory (Ipomoea)
We examined the genetic basis of resistance to the rust pathogen Coleosporium ipomoea in three host species: Ipomoea purpurea, I. hederacea, and I. coccinea (Convolvulaceae). In crosses between resistant and susceptible individuals, second-generation selfed offspring segregated in ratios that did not differ statistically from the 3:1 ratio indicative of single-gene resistance with the resistant...
