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’.
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.
Joint inference of evolutionary transitions to self ... - eLife
2023年5月11日 · Transitions from outcrossing to selfing, a major shift in mating systems, create a specific signature in intra-specific genetic polymorphisms, which can be used to infer the demographic history of populations and acquire valuable insights about the evolution of recombination rates.
Selfing - an overview | ScienceDirect Topics
Selfing is only beneficial if the advantages outweigh the costs associated with inbreeding depression and the reduction of genetic diversity. Self-compatibility has evolved in A. thaliana, which has the typical flower morphology of a self-fertilizing plant in contrast to its relatives, which are generally outcrossing [9].
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 ...
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 - an overview | ScienceDirect Topics
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. How clonal are Trypanosoma and Leishmania? Michel Tibayrenc, Francisco J. Ayala, in Trends in Parasitology, 2013.
Reproductive transitions in plants and animals: selfing …
Selfing syndrome traits often involve changes to male and female reproductive characters that were subject to sexual selection and sexual conflict in the obligatorily outcrossing ancestor, including the gametic phase for both plants and animals.
Plants capable of selfing are more likely to become naturalized
2016年10月31日 · Selfing ability is associated with annual or biennial life history and a large native range, which both positively correlate with the probability of naturalization. Path analysis suggests that...
