Partitioning Apomixis Components to Understand and Utilize Gametophytic Apomixis [PDF]
Frontiers in Plant Science, 2019 Apomixis is a method of reproduction to generate clonal seeds and offers tremendous potential to fix heterozygosity and hybrid vigor. The process of apomictic seed development is complex and comprises three distinct components, viz., apomeiosis (leading ...

The Rise of Apomixis in Natural Plant Populations [PDF]
Frontiers in Plant Science, 2019 Apomixis, the asexual reproduction via seed, has many potential applications for plant breeding by maintaining desirable genotypes over generations.

The Boechera Genus as a Resource for Apomixis Research [PDF]
Frontiers in Plant Science, 2019 The genera Boechera (A. Löve et D. Löve) and Arabidopsis, the latter containing the model plant Arabidopsis thaliana, belong to the same clade within the Brassicaceae family.

A pangenome-based approach reveals genes associated with polyploidy and apomixis in Eragrostis curvula. [PDF]
Plant GenomeAbstract Eragrostis curvula is a forage grass species in which multiple cytotypes coexist and shifts between sexual and apomictic reproduction are common. This study investigates genetic variation among these cytotypes in relation to ploidy levels and reproductive modes.

Molecular Basis of Apomixis in Plants [PDF]
, 2021 Apomixis is the consequence of a concerted mechanism that harnesses the sexual machinery and coordinates developmental steps in the ovule to produce an asexual (clonal) seed.

Theoretical and Applied Genetics, 2023 AbstractApomixis is an asexual mode of reproduction through seeds where progeny are clones of the mother plants. Naturally apomictic modes of reproduction are found in hundreds of plant genera distributed across more than 30 plant families, but are absent in major crop plants.

Apomixis: A Developmental Perspective
Annual Review of Plant Biology, 2003 The term apomixis encompasses a suite of processes whereby seeds form asexually in plants. In contrast to sexual reproduction, seedlings arising from apomixis retain the genotype of the maternal parent. The transfer of apomixis and its effective utilization in crop plants (where it is largely absent) has major advantages in agriculture.

The evolution of apomixis [PDF]
Heredity, 1981 The selective forces responsible for the evolution of gametophytic apomixis in outbreeding plant populations are analysed in terms of a simple single gene model. In the absence of selection, apomixis inevitably becomes fixed in a population. This conclusion holds regardless of the dominance relations of the alleles specifying apomictic versus sexual ...

Viewpoints on apornictic and sexual reproduction in angiosperms
Acta Societatis Botanicorum Poloniae, 2014 Gametophytic apomixis implies different changes of the reproductive cycle of sexual plants. Each of these "elements of apomixis" occurs in sexual plants, which may even display functional diploid parthenogenesis.

Dysplasia of male organs induces apomixis in Malus crabapples
Ornamental Plant Research, 2021 Apomixis has high value in fruit crop propagation and breeding applications, particularly for the transgenerational fixation of heterosis. In this study, we found that flowers of the triploid Malus cultivar 'Royalty' that were bagged after emasculation ...
