Development and characterization of microsatellite primers in Geranium carolinianum (Geraniaceae) with 454 sequencing1
UNLABELLED PREMISE OF THE STUDY Microsatellite primers were developed for Geranium carolinanum, a North American winter annual herb, for use in population genetic analyses. • METHODS AND RESULTS Genomic DNA enriched for repeat-containing fragments was sequenced on the Roche 454 Titanium platform, resulting in 470 primer pairs developed from 1115 microsatellite-containing sequences. A subse...
متن کاملFemale frequency and relative fitness of females and hermaphrodites in gynodioecious Geranium sylvaticum (Geraniaceae).
We determined female frequency of 23 populations of the gynodioecious Geranium sylvaticum (Geraniaceae) in Finland. We compared our results to previous results on this species from the 1960s in order to reveal putative changes in female frequencies. Because females may be maintained in gynodioecious populations if their seed production or offspring quality is higher than that of hermaphrodites,...
متن کاملFloral dimorphism, pollination, and self-fertilization in gynodioecious GERANIUM RICHARDSONII (Geraniaceae).
The selective maintenance of gynodioecy depends on the relative fitness of the male-sterile (female) and hermaphroditic morphs. Females may compensate for their loss of male fitness by reallocating resources from male function (pollen production and pollinator attraction) to female function (seeds and fruits), thus increasing seed production. Females may also benefit from their inability to sel...
متن کاملGender-specific inbreeding depression in a gynodioecious plant, Geranium maculatum (Geraniaceae).
In gynodioecious species, females coexist with hermaphrodites in natural populations even though hermaphrodites attract more pollinators, are capable of reproducing through pollen, and can self-fertilize. This study tests the hypothesis that inbreeding depression helps to maintain females in natural populations. It also examines whether gender lineages that differ in selfing rates might experie...
متن کاملFemale compensation through the quantity and quality of progeny in a gynodioecious plant, Geranium maculatum (Geraniaceae).
One of the major evolutionary trends in flowering plants is the evolution of unisexual flowers (male or female) from perfect flowers. This transition has occurred repeatedly in many taxa and has generated a wonderful array of variation in sexual expression among species. Theoretical studies have proposed a number of mechanisms to explain how this level of variation could be maintained in natura...
