Apomixis in agriculture: the quest for clonal seeds.

open access: yes, 2001
Apomixis, or asexual reproduction through seeds, is a natural trait that could have an immense positive impact on crop production. Apomictic breeding strategies could allow the fixation and indefinite propagation of any desired genotype, however complex.

Development of a reproductive calendar in Eragrostis curvula to guide transcriptomic studies of apomixis

open access: yes
Eragrostis curvula (weeping lovegrass) is a model system for studying diplosporous apomixis due to its unique reproductive mode, wide range of ploidy levels and reproductive behaviors and the availability of genomic and epigenomic tools.

Use of genotyping-by-sequencing to determine the genetic structure in the medicinal plant chamomile, and to identify flowering time and alpha-bisabolol associated SNP-loci by genome-wide association mapping

open access: yesBMC Genomics, 2017
Background Chamomile (Matricaria recutita L.) has a long history of use in herbal medicine with various applications, and the flower heads contain numerous secondary metabolites which are medicinally active.

Immanent Anthropology: A Comparative Study of 'Process' in Contemporary France [PDF]

open access: yes, 2014
This paper presents a comparative critique of the ‘processual temporalities’ which infuse both social-scientific theorizing and selected Western cultural practices.

A pattern of unique embryogenesis occurring via apomixis in Carya cathayensis

open access: yes, 2012
Apomixis represents an alteration of classical sexual plant reproduction to produce seeds that have essentially clonal embryos. In this report, hickory (Carya cathayensis Sarg.), which is an important oil tree, is identified as a new apomictic species ...

Apomixis in flowering plants: an overview [PDF]

open access: yesPhilosophical Transactions of the Royal Society of London. Series B: Biological Sciences, 2003
Apomixis is a common feature of perennial plants, which occurs in ca . 60% of the British flora, but has been largely ignored by reproductive theoreticians. Successful individuals may cover huge areas, and live to great ages, favoured by ‘symmetrical’ selection.

An AFLP marker tightly linked to apomixis reveals hemizygosity in a portion of the apomixis controlling locus in Paspalum simplex

open access: yes, 2002
A mapping population of Paspalum simplex segregating for apomixis (asexual reproduction through seeds) was screened with AFLPs to find apomixis-linked markers. Four AFLPs linked to apomixis in coupling phase were found.

Variation of microsporogenesis in sexual, apomictic and recombinant plants of Poa pratensis L

open access: yesCaryologia, 2022
Apomixis is a rather widespread phenomenon in plants. It is defined as the asexual formation of a seed from the maternal tissues of the ovule, avoiding the processes of meiosis and fertilization.

Apomixis in diploid × triploid Tripsacum dactyloides hybrids

open access: yes, 1991
Apomixis can hinder plant improvement if sexual or apomictic germ plasm of the appropriate ploidy level, required for effective manipulation of apomixis, is not available.
