Apomixis frequency under stress conditions in weeping lovegrass (Eragrostis curvula). [PDF]
PLoS ONE, 2017 To overcome environmental stress, plants develop physiological responses that are triggered by genetic or epigenetic changes, some of which involve DNA methylation.

Apomixis in Genista salzmannii DC. (Fabaceae) [PDF]
, 1991 Genista apomixis is described for the first time in two populations of Genista salzmannii DC.: the first is diploid and the second one tetraploid. There was no female meiosis and the megaspore mother cell functioned as an unreduced megaspore, which led ...

Identification of a molecular marker linked to apomixis in Brachiaria humidicola (Poaceae) [PDF]
, 2010 A bulked segregant analysis using RAPD technique was carried out to identify molecular markers linked to apomixis in a Brachiaria humidicola F1 population that segregated 1 : 1 for the mode of reproduction (apomixis and sexual).

New Phytologist, EarlyView.Summary The Arctic is experiencing some of the world's most rapid changes in climate. Arctic plant flowering time responses to climate change are understudied. Globally, conflicting evidence exists on whether flowering time responses to temperature are evolutionarily conserved.

The evolution of apomixis [PDF]
Heredity, 1981 The selective forces responsible for the evolution of gametophytic apomixis in outbreeding plant populations are analysed in terms of a simple single gene model. In the absence of selection, apomixis inevitably becomes fixed in a population. This conclusion holds regardless of the dominance relations of the alleles specifying apomictic versus sexual ...

Spotting the Targets of the Apospory Controller TGS1 in Paspalum notatum
Plants, 2022 Sexuality and apomixis are interconnected plant reproductive routes possibly behaving as polyphenic traits under the influence of the environment.

BMC Genomics, 2020 Background Paspalum notatum exhibits both sexual and apomictic cytotypes and, thus, is considered a good model for studies of apomixis because it facilitates comparative approaches. In this work, transcriptome sequencing was used to compare contrasting P.

Increased apomixis expression concurrent with genetic and epigenetic variation in a newly synthesized Eragrostis curvula polyploid [PDF]
, 2014 Eragrostis curvula includes biotypes reproducing through obligate and facultative apomixis or, rarely, full sexuality. We previously generated a ‘‘tetraploid-dihaploid-tetraploid’’ series of plants consisting of a tetraploid apomictic plant (T), a sexual
