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.

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)

Trends in Apomixis Research: The 10 Most Cited Research Articles Published in the Pregenomic and Genomic Eras

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

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.

Eragrostis curvula, a Model Species for Diplosporous Apomixis

Plants, 2021
Eragrostis curvula (Schrad.) Ness is a grass with a particular apomictic embryo sac development called Eragrostis type. Apomixis is a type of asexual reproduction that produces seeds without fertilization in which the resulting progeny is genetically ...

The relation of meiotic behaviour to hybridity, polyploidy and apomixis in the Ranunculus auricomus complex (Ranunculaceae)

BMC Plant Biology, 2020
Background Hybridization and polyploidization are powerful evolutionary factors that are associated with manifold developmental changes in plants such as irregular progression of meiosis and sporogenesis.
