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.

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.

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 ...

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.

Global transcriptome analysis of two ameiotic1 alleles in maize anthers: defining steps in meiotic entry and progression through prophase I [PDF]
, 2011 Background Developmental cues to start meiosis occur late in plants. Ameiotic1 (Am1) encodes a plant-specific nuclear protein (AM1) required for meiotic entry and progression through early prophase I. Pollen mother cells (PMCs) remain mitotic in most am1
