Temporal and spatial expression of genes involved in DNA methylation during reproductive development of sexual and apomictic Eragrostis curvula [PDF]
, 2017 Recent reports in model plant species have highlighted a role for DNA methylation pathways in the regulation of the somatic-to-reproductive transition in the ovule, suggesting that apomixis (asexual reproduction through seeds) likely relies on RdDM ...

Analysis of variation for apomictic reproduction in diploid Paspalum rufum [PDF]
, 2014 Background and Aims: The diploid cytotype of Paspalum rufum (Poaceae) reproduces sexually and is self-sterile; however, recurrent autopolyploidization through 2n + n fertilization and the ability for reproduction via apomixis have been documented in one ...

Frontiers in Plant Science, 2020 Forage grasses are mainly used in animal feed to fatten cattle and dairy herds, and guinea grass (Megathyrsus maximus) is considered one of the most productive of the tropical forage crops that reproduce by seeds.

In vitro culture and apogamy: Alternative pathway in the life cycle of the moss Amblystegium serpens (Amblystegiaceae) [PDF]
, 2005 In vitro culture of the moss Amblystegium serpens (Amblystegiaceae) was established on hormone-free Murashige and Skoog (MS) medium that contained a half amount of MS micro- and macro- mineral salts and vitamins, 100 mg/l myoinositol, 30 g/l sucrose, and

BMC Genomics, 2021 Background Apomixis, an asexual mode of plant reproduction, is a genetically heritable trait evolutionarily related to sexuality, which enables the fixation of heterozygous genetic combinations through the development of maternal seeds.

Harnessing the developmental potential of nucellar cells: Barriers and opportunities [PDF]
, 2004 Angiosperm nucellar cells can either use or avoid meiosis in vivo, depending on the developmental context. This unique ability contrasts with the conditions required in vitro, either for a reconstituted oocyte to avoid meiosis and produce clones by ...

Gametophyte and sporophyte of tree ferns in vitro culture
Acta Societatis Botanicorum Poloniae, 2011 Experiments had been carried out on gametophytes and very young fronds of sporophytes with application of Murashige and Skoog (1962) medium. The paper described the results of 15 years in vitro experiments on 16 species of tree ferns belonging to various

Biological Reviews, Volume 95, Issue 5, Page 1442-1466, October 2020., 2020 ABSTRACT Although most plants produce all of their fruits (seeds) aboveground, amphicarpic species produce fruits (seeds) both above‐ and belowground. Our primary aims were to determine the number of reported amphicarpic species and their taxonomic, geographic, life form and phylogenetic distribution, to evaluate differences in the life history of ...
