Data_Sheet_1_Evolution of an Apomixis-Specific Allele Class in Supernumerary Chromatin of Apomictic Boechera.docx

, 2022
Asexual reproduction through seeds in plants (i.e., apomixis) is a heritable trait, and apomixis- linked loci have been identified in multiple species. However, direct identification of genomic elements is typically hindered as apomixis-linked loci and ...

Image_2_Apospory and Diplospory in Diploid Boechera (Brassicaceae) May Facilitate Speciation by Recombination-Driven Apomixis-to-Sex Reversals.TIF

, 2019
Apomixis (asexual seed formation) in angiosperms occurs either sporophytically, through adventitious embryony, or gametophytically, where an unreduced female gametophyte (embryo sac) forms and produces an unreduced egg that develops into an embryo ...

DNA Methylation and Stress-induced Reversions from Asexual to Sexual Seed Formation in Boechera (Brassicacea) [PDF]

, 2016
Apomixis is a form of asexual reproduction that occurs in many plants and animals. Eggs of apomictic plants and animals form by apomeiosis, which means they do not become genetically reduced.

Clonal seed formation by synthetic Apomixis: challenges and engineering modules for genotype fixation and cultivar maintenance

Horticulture Research
Modern breeding has benefited substantially from genetic recombination and heterosis associated with sexual reproduction. However, sexual reproduction also causes trait segregation, making elite phenotypes and complex genotypes difficult to maintain ...

From a Phenotype to Transcriptomics Apomixis Initiation in the genus Boechera [PDF]

, 2009
The North American genus Boechera provides a highly polymorphic source of natural variation for studies on the regulation of apomictic development (asexual reproduction via seed).

A Conserved Apomixis-Specific Polymorphism Is Correlated with Exclusive Exonuclease Expression in Premeiotic Ovules of Apomictic Boechera Species1[W][OPEN]

Plant Physiology, 2013
A single gene characterized by a conserved apomixis-specific polymorphism is exclusively expressed in the ovules of genetically diverse apomictic Boechera species while being repressed in ovules of sexuals.

Sporophytic ovule tissues modulate the initiation and progression of apomixis in Hieracium [PDF]

, 2012
Apomixis in Hieracium subgenus Pilosella initiates in ovules when sporophytic cells termed aposporous initial (AI) cells enlarge near sexual cells undergoing meiosis.

Disclosing the Molecular Link between Apospory and Diplospory

, 2021
Gametophytic apomixis forms seeds with clonal embryos identical to the mother plant through two different mechanisms, namely apospory and diplospory, both of them involving the formation of nonreduced megagametophytes within the ovule.
