Pollination dynamics variation in a Douglas-fir seed orchard as revealed by microsatellite analysis

Silva Fennica, 2016
As part of a multi-year monitoring study of pollination dynamics in a second generation Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) seed orchard, we estimated with the aid of eight microsatellite markers three important reproductive biology ...

Strong inbreeding depression and individually variable mating system in the narrow endemic Erodium cazorlanum (Geraniaceae)

Anales del Jardín Botánico de Madrid, 2013
Angiosperms evolved different systems to attract effective pollinators while reducing selfing in hermaphroditic flowers. Selfing ability can be advantageous when pollinators and/or mates are scarce, although inbreeding depression may largely reduce those

Inheritance of high stearic acid content in sunflower seed oil

Труды по прикладной ботанике, генетике и селекции
Background. Development of sunflower hybrids with a semisolid oil type induced by higher stearic acid content attracts attention as a nutritionally sound alternative to palm oil and hydrogenated trans fats.

Genome-wide patterns of segregation and linkage disequilibrium: the construction of a linkage genetic map of the poplar rust fungus Melampsora larici-populina

Frontiers in Plant Science, 2014
The poplar rust fungus Melampsora larici-populina causes significant yield reduction and severe economic losses in commercial poplar plantations. After several decades of breeding for qualitative resistance and subsequent breakdown of the released ...

Experimental evolution suggests rapid assembly of the ‘selfing syndrome’ from standing variation in Mimulus guttatus

Frontiers in Plant Science
Ecological and evolutionary changes are likely to occur rapidly when outcrossing populations experience pollinator loss. However, the number and identify of plant traits that will respond to this form of selection, as well as the overall predictability ...

Multiple aspects of the selfing syndrome of the morning glory Ipomoea lacunosa evolved in response to selection: A Qst‐Fst comparison

Ecology and Evolution, 2019
The frequent transition from outcrossing to selfing in flowering plants is often accompanied by changes in multiple aspects of floral morphology, termed the “selfing syndrome.” While the repeated evolution of these changes suggests a role for natural ...
