The selfing syndrome and beyond: diverse evolutionary …
The shift from outcrossing to self-fertilization (selfing) is considered one of the most prevalent evolutionary transitions in flowering plants. Selfing species tend to share similar reproductive traits in morphology and function, and such a set of traits is called the ‘selfing syndrome’.
Selfing syndrome - Wikipedia
Selfing syndrome refers to plants that are autogamous and display a complex of characteristics associated with self-pollination. [1]
Selfing - an overview | ScienceDirect Topics
Highly selfing species often share a suit of traits that constitute a selfing syndrome. Specifically, traits associated with high autonomous selfing are low herkogamy (i.e., anther-stigma distance) and low dichogamy (i.e., temporal separation between mature anthers and mature stigmas, Figure I …
The selfing syndrome: a model for studying the genetic and …
2011年2月7日 · The change from outbreeding (also called xenogamy or allogamy) to autogamous selfing, i.e. selfing within a hermaphroditic flower, is generally associated with a characteristic set of changes to the morphology and function of flowers, termed the selfing syndrome (Darwin, 1876; Ornduff, 1969; Richards, 1986).
The Genomic Selfing Syndrome Accompanies the Evolutionary …
2020年8月6日 · We found both macro- and microevolutionary evidence for components of the genomic selfing syndrome. The transition to selfing via homostyle evolution has resulted in significant effects on genetic diversity, the efficacy of selection, and on rates of adaptive evolution.

Selfing refers to mating between identical genotypes, which can be issued from the same clone (Tibayrenc et al., 2010). You might find these chapters and articles relevant to this topic.

Selfing - an overview | ScienceDirect Topics
Selfing is practiced to prevent natural cross-pollination and to maintain the purity of a variety. It is also used to develop true breeding lines and to increase the homozygosity. In self-pollinated crops, selfing has no adverse effects on vigor or fertility as it is natural mode of pollination in such crops and no separate (human interference ...
How broad is the selfing syndrome? Insights from convergent …
In summary, the impact of selfing on both flower morphology (Woźniak et al., 2020) and genetic load (Kryvokhyzha et al., 2019a) have already been thoroughly described in Capsella, and in both cases there was evidence of a strong selfing syndrome.
Reproductive transitions in plants and animals: selfing …
2019年7月23日 · In this synthesis, I will focus on evolutionary transitions from obligate outcrossing to predominant self-fertilisation, with particular emphasis on scenarios of autonomous (within-flower) selfing that link most easily between plant and animal systems.
The Evolution of Selfing in Arabidopsis thaliana | Science - AAAS
2007年8月24日 · Unlike most of its close relatives, Arabidopsis thaliana is capable of self-pollination. In other members of the mustard family, outcrossing is ensured by the complex self-incompatibility (S) locus,which harbors multiple diverged specificity haplotypes that …
