Can ploidy changes propel the evolution of allogamy in a selfing species complex? [PDF]

BMC Plant Biology
Background The transition to self-fertilization has occurred repeatedly across diverse plant groups, and the evolutionary consequences of selfing typically suggest that a shift toward outcrossing is unlikely.

Floral and pollination biology of dragon fruit reveals strategies for enhancing productivity through pollination management and reproductive window extension [PDF]

Scientific Reports
Dragon fruit (Selenicereus undatus (Haw.) D.R. Hunt) is emerging as a high-value crop globally. However, its reproductive biology remains poorly characterized, with conflicting reports ranging from strict self-incompatibility (allogamy) to self ...

Iterative allogamy-autogamy transitions drive actual and incipient speciation during the ongoing evolutionary radiation within the orchid genus Epipactis (Orchidaceae). [PDF]

Ann Bot, 2019
BACKGROUND AND AIMS The terrestrial orchid genus Epipactis has become a model system for the study of speciation via transitions from allogamy to autogamy, but close phylogenetic relationships have proven difficult to resolve through Sanger sequencing.

Allogamy, metaxenia and hybrids in orchids, what do we know about it?

Botan‪ical Sciences
Orchids are a diverse group of plants, also manifested in their great diversity of flowers. Despite this, orchids are pollinated either through autogamy or allogamy (geitonogamy and xenogamy). Although there are some autogamous orchids, the majority are

Morphofunctional Traits and Pollination Mechanisms of Coronilla emerus L. Flowers (Fabaceae) [PDF]

The Scientific World Journal, 2012
It is accepted that the papilionaceous corolla of the Fabaceae evolved under the selective pressure of bee pollinators. Morphology and function of different parts of Coronilla emerus L. flowers were related to their role in the pollination mechanism. The

Allogamy-Autogamy Switch Enhance Assortative Mating in the Allotetraploid Centaurea seridis L. Coexisting with the Diploid Centaurea aspera L. and Triggers the Asymmetrical Formation of Triploid Hybrids. [PDF]

PLoS ONE, 2015
Hybridization between tetraploids and their related diploids is generally unsuccessful in Centaurea, hence natural formation of triploid hybrids is rare. In contrast, the diploid Centaurea aspera and the allotetraploid C.

Can changes in ploidy drive the evolution to allogamy in a selfing species complex?

bioRxiv, 2023
The evolution of mating systems in plants is central for understanding the rise of their diversity on Earth. The transition towards self-fertilization is a well-known example of convergent evolution although the opposite direction is expected to be ...
