Dysplasia of male organs induces apomixis in Malus crabapples
Ornamental Plant Research, 2021 Apomixis has high value in fruit crop propagation and breeding applications, particularly for the transgenerational fixation of heterosis. In this study, we found that flowers of the triploid Malus cultivar 'Royalty' that were bagged after emasculation ...

Turning meiosis into mitosis. [PDF]
PLoS Biology, 2009 Apomixis, or asexual clonal reproduction through seeds, is of immense interest due to its potential application in agriculture. One key element of apomixis is apomeiosis, a deregulation of meiosis that results in a mitotic-like division.

Frontiers in Plant Science, 2022 Apomixis, or asexual reproduction by seed, represents an easy shortcut for life cycle renewal based on maternal embryo production without ploidy reduction (meiosis) and ploidy restitution (syngamy). Although the first studies officially published on this

Implications of hybridisation and cytotypic differentiation in speciation assessed by AFLP and plastid haplotypes : a case study of Potentilla alpicola La Soie [PDF]
, 2012 Background: Hybridisation is presumed to be an important mechanism in plant speciation and a creative evolutionary force often accompanied by polyploidisation and in some cases by apomixis. The Potentilla collina group constitutes a particularly suitable

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

Pistil transcriptome analysis to disclose genes and gene products related to aposporous apomixis in Hypericum perforatum L. [PDF]
, 2017 Unlike sexual reproduction, apomixis encompasses a number of reproductive strategies,which permit maternal genome inheritance without genetic recombination and syngamy.

Toward in vitro fertilization in Brachiaria spp. [PDF]
, 2010 Brachiaria are forage grasses widely cultivated in tropical areas. In vitro pollination was applied to accessions of Brachiaria spp. by placing pollen of non-dehiscent anthers on a solid medium near isolated ovaries.
