Development and evaluation of microsatellite markers for the gynodioecious shrub Daphne jezoensis (Thymelaeaceae)1
UNLABELLED PREMISE OF THE STUDY Ten microsatellite markers were developed and characterized in a gynodioecious summer-deciduous shrub, Daphne jezoensis, to facilitate studies of the evolution of gynodioecy in the species. • METHODS AND RESULTS We used a next-generation sequencing approach with the Ion Personal Genome Machine (PGM) system to identify and develop microsatellite markers with ...
متن کاملHerbivores do not discriminate between leaves of female and hermaphrodite individuals of gynodioecious Daphne laureola (Thymelaeaceae)
The outcome of plant-animal interactions in dioecious plant species frequently depends on the gender of the plant individuals. It has even been proposed that these interactions could mediate the evolution of plant reproductive systems from hermaphroditism to dioecy. Gynodioecy is the most frequent intermediate stage in this evolutionary process, however, little is known about the relevance of g...
متن کاملNeither vegetative nor reproductive advantages account for high frequency of male-steriles in southern Spanish gynodioecious Daphne laureola (Thymelaeaceae).
In gynodioecious species, male-steriles (termed "females" hereafter) usually exhibit some reproductive advantage over hermaphrodites that allow them to compensate for the loss of male reproductive function. This compensation can result from higher fecundity, vegetative outperformance, and/or lower inbreeding depression. In this study we compared vegetative and reproductive parameters of female ...
متن کاملVariation in herbivory within and among plants of Daphne laureola (Thymelaeaceae): correlation with plant size and architecture
The evolutionary implications of plant-herbivore relationships cannot be understood without elucidating (I) why all individuals in a plant population are not equally damaged, and whether differences in herbivory levels are random, relate to environmental conditions or depend on intrinsic (i.e. potentially heritable) plant features and (2) whether differential herbivory has fitness-related conse...
متن کاملPhytotoxicity of Daphne Gnidium L. Occurring in Tunisia
Phytotoxicity of Daphne gnidium L. was evaluated through the effect of incorporating leaves, stems and roots biomass into soil (at 12.5, 25, 50g/Kg) and irrigation by their aqueous extracts (50g/L), on the growth of two crops (Lactuca sativa L. and Raphanus sativus L.) and two weeds (Peaganum harmala L. and Scolymus maculatus L.). Results revealed a perceptible phytotoxic effect which increased...
