To infinity and beyond: recent progress, bottlenecks, and potential of clonal seeds by apomixis
The Plant Journal, Volume 121, Issue 4, February 2025.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.

Features of embryonic development in sugar beet under apospory and cytoplasmic male sterility
Рослинництво та ґрунтознавствоThe aim of the study was to evaluate the theoretical foundations of the phenomenon of high seed self-reproduction in substituted lines and to develop a methodology for studying embryonic development in sugar beet breeding materials with cytoplasmic male ...

Natural Apospory in Pteridium?
American Fern Journal, 1966 From a population of the bracken fern in New Hampshire, Farlow (1889) described prothalloid outgrowths from the marginal sori. He concluded that natural apospory, i.e. the formation of a gametophyte vegetatively from a sporophyte under normal environmental conditions, had occurred as reported by Druery (1884) and Bower (1884).

A unique life cycle transition in the red seaweed Pyropia yezoensis depends on apospory
, 2019 Plant life cycles consist of two temporally separated stages: a haploid gametophyte and a diploid sporophyte. In plants employing a haploid-diploid sexual life cycle, the transition from sporophyte to gametophyte generally depends on meiosis.

Apospory and parthenogenesis may be uncoupled in Poa pratensis: a cytological investigation
, 2001 Despite the potential that apomixis has for agriculture, there is little information regarding the genetic control of its functional components. We carried out a cytohistological investigation on an F1 segregating population of Poa pratensis obtained ...
