Maternal haploid induction in maize via mutation of Gamete Expression protein 1
Plant Biotechnology Journal, Volume 23, Issue 7, Page 2595-2607, July 2025.Summary Doubled haploid (DH) technology, based on haploid induction (HI), is a crucial tool in enhancing crop‐breeding efficiency and has been successfully applied in various plant species. While many HI‐related genes have been identified using diverse strategies, the genetic basis and molecular mechanisms underlying HI remain incompletely understood ...

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 ...

The Plant Journal, Volume 122, Issue 6, June 2025.SUMMARY Oryza sativa BABY BOOM 1 (OsBBM1), a member of the AP2/ERF family of transcription factors, is expressed from paternal allele in rice zygote and plays a crucial role in initiating zygotic development. However, the mechanism how the paternal OsBBM1 drives this development remains unclear. Rice zygotes with four different gamete combinations with

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.

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).

Apospory in Pteris sulcata L. [PDF]
Botanical Gazette, 1919 1. The gametophyte generation of Pteris sulcata L. is ordinarily produced by the germination of a spore. 2. The embryo sporophyte is of apogamous origin. 3. The gametophyte generation of Pteris sulcata under certain conditions was produced aposporously. 4.

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.

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.
