Asexual reproduction through seeds: the complex case of diplosporous apomixis [PDF]

open access: yes, 2023
Apomixis is considered a potentially revolutionary tool to generate high-quality food at a lower cost and shorter developmental time due to clonal seed production through apomeiosis and parthenogenesis.

Molecular Basis of Apomixis in Plants [PDF]

open access: yes, 2022
Apomixis is the consequence of a concerted mechanism that harnesses the sexual machinery and coordinates developmental steps in the ovule to produce an asexual (clonal) seed.

Apomictic and sexual germline development differ with respect to cell cycle, transcriptional, hormonal and epigenetic regulation. [PDF]

open access: yesPLoS Genetics, 2014
Seeds of flowering plants can be formed sexually or asexually through apomixis. Apomixis occurs in about 400 species and is of great interest for agriculture as it produces clonal offspring. It differs from sexual reproduction in three major aspects: (1)

Widespread application of apomixis in agriculture requires further study of natural apomicts. [PDF]

open access: yesiScience
Apomixis, or asexual reproduction through seeds, is frequent in nature but does not exist in any major crop species, yet the phenomenon has captivated researchers for decades given its potential for clonal seed production and plant breeding. A discussion

Pistil transcriptome analysis to disclose genes and gene products related to aposporous apomixis in Hypericum perforatum L. [PDF]

open access: yes, 2017
Unlike sexual reproduction, apomixis encompasses a number of reproductive strategies,which permit maternal genome inheritance without genetic recombination and syngamy.

New records and observations of macroalgae and associated pathogens from the Falkland Islands, Patagonia and Tierra del Fuego [PDF]

open access: yes, 2016
Subantarctic and Antarctic regions remain little explored with regards to their seaweed diversity. This study is based upon collections in the early 1970s and 2007–2013.

Harnessing the developmental potential of nucellar cells: Barriers and opportunities [PDF]

open access: yes, 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 ...

Transient Activation of Apomixis in Sexual Neotriploids May Retain Genomically Altered States and Enhance Polyploid Establishment

open access: yesFrontiers in Plant Science, 2018
Polyploid genomes evolve and follow a series of dynamic transfigurations along with adaptation and speciation. The initial formation of a new polyploid individual within a diploid population usually involves a triploid bridge, a two-step mechanism of ...

De novo sequencing of the Hypericum perforatum L. flower transcriptome to identify potential genes that are related to plant reproduction sensu lato [PDF]

open access: yes, 2015
Background: St. John's wort (Hypericum perforatum L.) is a medicinal plant that produces important metabolites with antidepressant and anticancer activities.
