Adaptation et autogamie

, 2023
Plus de 40% des plantes à fleur peuvent faire de l’autofécondation et 10 à 20% d’entre elles se reproduisent majoritairement par autofécondation, ce qui façonne de façon majeure la diversité et la structure génétique des populations. En particulier, on s’attend à ce que la diminution d’effectif efficace due à l’autofécondation limite la diversité ...

APPLE BREEDING PROGRAMS AND METHODS: THEIR DEVELOPMENT AND IMPROVEMENT

Вавиловский журнал генетики и селекции, 2015
Long-term studies of apple development features allowed breeding intensification and shortening of the time of cultivar development from 36–48 years to 23–27 or even 13–17 years. It is noted that requirements for cultivar are constantly toughened.

Genomic Signatures of North American Soybean Improvement Inform Diversity Enrichment Strategies and Clarify the Impact of Hybridization

G3: Genes, Genomes, Genetics, 2016
Crop improvement represents a long-running experiment in artificial selection on a complex trait, namely yield. How such selection relates to natural populations is unclear, but the analysis of domesticated populations could offer insights into the ...

Autogamy vs. Allogamy: Biotic-Dependent Populations Reveal Shift in the Reproduction System of an Essentially Autogamous Vanilla

Diversity
Flowering plants have evolved a wide range of strategies to avoid self-fertilization. Although allogamy is common among members of the genus Vanilla, V. lindmaniana is widely known for its ability to self-fertilize, resulting in fruit-set rates of 83–100%

Pollinator availability, mating system and variation in flower morphology in a tropical savanna tree

Acta Botânica Brasílica
Widely distributed organisms face different ecological scenarios throughout their range, which can potentially lead to micro-evolutionary differentiation at specific localities.

A novel strategy to study apomixis, automixis, and autogamy in plants

Plant Reproduction
Abstract Key message The combination of a flow cytometric seed screen and genotyping of each single seed offers a cost-effective approach to detecting complex reproductive pathways in flowering plants. Abstract Reproduction may be seen as one of the driving forces of ...

Estrategia reproductiva de una hierba perenne: Hypoxis decumbens (Hypoxidaceae)

Revista de Biología Tropical, 1998
Se estudió la estrategia reproductiva de Hypoxis decumbens L. (Hypoxidaceae), una hierba perenne con flores hermafroditas, para comprobar las relaciones que se establecen entre sistema reproductivo, forma de vida, ambiente, sistema de polinización y ...
