Apomixis frequency under stress conditions in weeping lovegrass (Eragrostis curvula)
(Public Library of Science, 2017-04)
To overcome environmental stress, plants develop physiological responses that are triggered by genetic or epigenetic changes, some of which involve DNA methylation. It has been proposed that apomixis, the formation of ...
A molecular map of the apomixis-control locus in Paspalum procurrens and its comparative analysis with other species of Paspalum
(Springer, 2011-10)
Since apomixis was first mapped in Paspalum, the absence of recombination that characterizes the related locus appeared to be the most difficult bottleneck to overcome for the dissection of the genetic determinants that ...
Polyploidy and apomixis in accessions of Senna rugosa (G.Don) H.S.Irwin & Barneby

Harnessing apomictic reproduction in grasses : what we have learnt from Paspalum
(Oxford University Press, 2013-07-17)
Background Apomixis is an alternative route of plant reproduction that produces individuals genetically identical to the mother plant through seeds. Apomixis is desirable in agriculture, because it guarantees the perpetuation ...
Heterochronic reproductive developmental processes between diploid and tetraploid cytotypes of Paspalum rufum
(Oxford University Press, 2019-05)
BACKGROUND AND AIMS: Apomixis is an asexual reproductive mode via seeds that generate maternal clonal progenies. Although apomixis in grasses is mainly expressed at the polyploid level, some natural diploid genotypes of ...
Harnessing apomictic reproduction in grasses : what we have learned from paspalum
(Oxford University Press, 2013-09)
Background: Apomixis is an alternative route of plant reproduction that produces individuals genetically identical to the mother plant through seeds. Apomixis is desirable in agriculture, because it guarantees the perpetuation ...
Increased apomixis expression concurrent with genetic and epigenetic variation in a newly synthesized Eragrostis curvula polyploid
(Macmillan, 2014-04)
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 ...
Breeding Tetraploid Paspalum simplex : Hybridization, Early Identification of Apomicts, and Impact of Apomixis on Hybrid Performance
(Crop Science Society of America, 2019-03)
Apomictic grasses predominate among tropical forages, and specific breeding techniques are needed for their genetic improvement. The objectives were to: 1- generate hybrids by crossing tetraploid sexual and apomictic ...
Caracterización de semillas de diferentes accesiones de tunas (Opuntia ficus-indica (L.) Mill.), en relación a su ploidía y apomixis
(Universidad de Chile, 2017)
La tuna es una de las especies de cactus más importante económicamente a nivel mundial, debido principalmente a la posibilidad de producirla en zonas áridas y semiáridas y los variados productos que se pueden obtener de ...
