Pathways to polyploidy : indications of a female triploid bridge in the alpine species Ranunculus kuepferi (Ranunculaceae) [PDF]
, 2017 Polyploidy is one of the most important evolutionary processes in plants. In natural populations, polyploids usually emerge from unreduced gametes which either fuse with reduced ones, resulting in triploid offspring (triploid bridge), or with other ...

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

Die Funktion des Responseregulators ARR2 in der Entwicklung von Arabidopsis thaliana [PDF]
, 2004 In dieser Arbeit konnte mittels physiologischer Experimente, Expressionsanalysen, Phosphorylierungsassays und Transaktivierungsanalysen eine komplexe Funktion von ARR2 in verschiedenen Signaltransduktionswegen von Arabidopsis aufgedeckt werden.

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.

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).

Timing of megasporogenesis in Tripsacum species (Poaceae) as related to the control of apoximis and sexuality [PDF]
, 1994 Chez différentes espèces pseudogames aposporiques (#Panicum maximum, Ranunculus auricomus, Paspalumnotatum$), des différences pour la durée de la mégasporogenèse ont été observées entre les formes sexuées et aposporiques ; les gamétophytes femelles ...

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.
