Retracing the molecular basis and evolutionary history of the loss of benzaldehyde emission in the genus Capsella [PDF]

open access: yes, 2019
The transition from pollinator‐mediated outbreeding to selfing has occurred many times in angiosperms. This is generally accompanied by a reduction in traits attracting pollinators, including reduced emission of floral scent.

Evolutionary implications of a high selfing rate in the freshwater snail Lymnaea truncatula. [PDF]

open access: yes, 2003
Self-compatible hermaphroditic organisms that mix self-fertilization and outcrossing are of great interest for investigating the evolution of mating systems.

Herkogamy and its effects on mating patterns in Arabidopsis thaliana. [PDF]

open access: yesPLoS ONE, 2013
The evolution of mating systems, which exhibit an extraordinary diversity in flowering plants, is of central interest in plant biology. Herkogamy, the spatial separation of sexual organs within flowers, is a widespread floral mechanism that is thought to

Multiple independent origins of auto-pollination in tropical orchids (Bulbophyllum) in light of the hypothesis of selfing as an evolutionary dead end [PDF]

open access: yes, 2015
Background: The transition from outcrossing to selfing has long been portrayed as an ‘evolutionary dead end because, first, reversals are unlikely and, second, selfing lineages suffer from higher rates of extinction owing to a reduced potential for ...

Genetic analysis of safflower domestication. [PDF]

open access: yes, 2014
BackgroundSafflower (Carthamus tinctorius L.) is an oilseed crop in the Compositae (a.k.a. Asteraceae) that is valued for its oils rich in unsaturated fatty acids.

Occipital condyle syndrome: self diagnosed

open access: yesBMJ Case Reports, 2009
We present the case of a 71-year-old man who presented to us with unilateral lower motor neuron hypoglossal palsy along with the characteristic occipital headache. He himself forwarded a paper on occipital condyle syndrome to the clinician who initially reviewed him. Later the patient underwent a series of investigations that confirmed the diagnosis of

Enhancing legume ecosystem services through an understanding of plant–pollinator interplay [PDF]

open access: yes, 2016
Legumes are bee-pollinated, but to a different extent. The importance of the plant– pollinator interplay (PPI), in flowering crops such as legumes lies in a combination of the importance of pollination for the production service and breeding strategies ...

Selection favors loss of floral pigmentation in a highly selfing morning glory.

open access: yesPLoS ONE, 2020
A common evolutionary trend in highly selfing plants is the evolution of the "selfing syndrome", in which traits associated with pollinator attraction are lost or greatly reduced.

Inbreeding depression is high in a self-incompatible perennial herb population but absent in a self-compatible population showing mixed mating. [PDF]

open access: yes, 2017
High inbreeding depression is thought to be one of the major factors preventing evolutionary transitions in hermaphroditic plants from self-incompatibility (SI) and outcrossing toward self-compatibility (SC) and selfing. However, when selfing does evolve,

De novo sequence assembly and characterization of the floral transcriptome in cross- and self-fertilizing plants

open access: yesBMC Genomics, 2011
Background The shift from cross-fertilization to predominant self-fertilization is among the most common evolutionary transitions in the reproductive biology of flowering plants.
