Genetics and Molecular Biology, 2012 In previous studies we reported the identification of several AFLP, RAPD and RFLP molecular markers linked to apospory in Paspalum notatum. The objective of this work was to sequence these markers, obtain their flanking regions by chromosome walking and ...

Small RNA-seq reveals novel regulatory components for apomixis in Paspalum notatum
BMC Genomics, 2019 Background Apomixis is considered an evolutionary deviation of the sexual reproductive pathway leading to the generation of clonal maternal progenies by seeds.

Food Frontiers, Volume 6, Issue 2, Page 1027-1040, March 2025.ABSTRACT The senescence of leafy vegetables is inherent and general after harvest. DNA methylation affects the senescence process of plant leaves. Limited studies have explored the impact of exogenous methylation inhibitors on postharvest vegetables and the mechanisms of their effects on the transcriptome and metabolome during storage.

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).

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.

Apospory appears to accelerate onset of meiosis and sexual embryo sac formation in sorghum ovules
BMC Plant Biology, 2011 Background Genetically unreduced (2n) embryo sacs (ES) form in ovules of gametophytic apomicts, the 2n eggs of which develop into embryos parthenogenetically. In many apomicts, 2n ES form precociously during ovule development.
