Variation in reproductive systems facilitates species boundaries of sympatric Vriesea (Bromeliaceae)
(2017-06-01)
Divergence in reproductive systems among plant species often involves changes in floral traits. The distance separating stigmas and anthers (herkogamy) directly affects the relative importance of reproduction by outcrossing ...
Expression of internal reproductive barriers in a germplasm bank accession of the wild potato Solanum chacoense Bitter in three ex situ regeneration cycles
(Springer, 2021-03)
Wild potatoes (Solanum sp.) are important reservoirs of desirable genes for potato breeding. Most of them are diploid and obligate outcrossers, with both sexual and asexual reproduction. Samples of natural populations are ...
Strong but permeable barriers to gene exchange between sister species of Epidendrum
(Botanical Soc Amer Inc, 2016-08-01)
PREMISE OF THE STUDY: The investigation of reproductive barriers between sister species can provide insights into how new lineages arise, and how species integrity is maintained in the face of interspecific gene flow. ...
Barriers To Gene Flow And Ring Species Formation
(Wiley-BlackwellHoboken, 2017)
Pollinators and crossability as reproductive isolation barriers in two sympatric oil rewarding Calceolaria (Calceolariaceae) species
(Springer, 2017)
Pollinator species are widely accepted as an important factor in plant reproductive
isolation. Although mostly investigated in plants visited by different groups of
pollinators (e.g., hummingbirds vs bees), few studies ...
Phylogeographic Structure And Outbreeding Depression Reveal Early Stages Of Reproductive Isolation In The Neotropical Orchid Epidendrum Denticulatum
(2013-07-01)
Phylogeographic studies provide an important framework for investigating the mechanisms operating during the earliest stages of speciation, as reproductive barriers can be examined among divergent lineages in a geographic ...

Reproductive compatibility studies between wild and cultivated strawberries (Fragaria × ananassa) to obtain “bridge species” for breeding programmes
(Wiley Blackwell Publishing, Inc, 2019-04)
The Fragaria genus has become relevant due to worldwide economic importance of the octoploid hybrid F. × ananassa. Interspecific hybridizations are widely employed in breeding programmes to introduce useful characteristics ...
