Options for Engineering Apomixis in Plants [PDF]

Frontiers in Plant Science, 2022
In plants, embryogenesis and reproduction are not strictly dependent on fertilization. Several species can produce embryos in seeds asexually, a process known as apomixis.

Apomictic Malus plants exhibit abnormal pollen development [PDF]

Frontiers in Plant Science, 2023
Apomixis is the asexual reproduction through seeds that leads to the production of genetically uniform progeny. It has become an important tool in plant breeding because it facilitates the retention of genotypes with desirable traits and allows seeds to ...

To infinity and beyond: recent progress, bottlenecks, and potential of clonal seeds by apomixis. [PDF]

Plant J
SUMMARY Apomixis – clonal seed production in plants – is a rare yet phylogenetically widespread trait that has recurrently evolved in plants to fix hybrid genotypes over generations. Apomixis is absent from major crop species and has been seen as a holy grail of plant breeding due to its potential to propagate hybrid vigor in perpetuity.

Partitioning Apomixis Components to Understand and Utilize Gametophytic Apomixis

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 ...

Variability of Reproduction Pathways in the Central-European Populations of Hawthorns with Emphasis on Triploids

Plants, 2022
The role of apomeiosis, parthenogenesis, and pseudogamy in the asexual reproduction of some plant groups has not been fully elucidated in relation to species diversification.

Diploid gametes in maize by mutation of A-Type cyclins: a step towards apomeiosis and synthetic apomixis

bioRxiv
Abstract Hybrid crops are agriculturally desirable due to heterosis but are costly or difficult to produce. Synthetic apomixis, clonal reproduction through seed, offers the ability to fix hybrid vigor. Two components are needed to achieve this goal: the formation of diploid gametes identical to the maternal parent ...

Sex- versus apomixis-specific polymorphisms in the 5′UTR of APOLLO from Boechera shift gene expression from somatic to reproductive tissues in Arabidopsis

Frontiers in Plant Science
IntroductionAmong candidate genes underlying the control components of apomixis, APOLLO is known for its strong linkage to apomeiosis in the genus Boechera.

Depletion of Key Meiotic Genes and Transcriptome-Wide Abiotic Stress Reprogramming Mark Early Preparatory Events Ahead of Apomeiotic Transition

Frontiers in Plant Science, 2016
Molecular dissection of apomixis - an asexual reproductive mode - is anticipated to solve the enigma of loss of meiotic sex, and to help fixing elite agronomic traits.
