Eragrostis curvula, a Model Species for Diplosporous Apomixis

open access: yesPlants, 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 Rise of Apomixis in Natural Plant Populations

open access: yesFrontiers in Plant Science, 2019
Apomixis, the asexual reproduction via seed, has many potential applications for plant breeding by maintaining desirable genotypes over generations.

Evolutionary role of apomixis: S. S. Khokhlov’s hypothesis in the light of modern data [PDF]

open access: yesИзвестия Саратовского университета. Новая серия: Серия Химия. Биология. Экология, 2022
In 1949 S. S. Khokhlov (one of the founders of the Russian scientifi c school on the problem of apomixes) proved the original conception of the progressive evolutionary role of apomixis.

Implications of hybridisation and cytotypic differentiation in speciation assessed by AFLP and plastid haplotypes : a case study of Potentilla alpicola La Soie [PDF]

open access: yes, 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

open access: yesBMC Genomics, 2019
Background Weeping lovegrass (Eragrostis curvula [Shrad.] Nees) is a perennial grass found in semi-arid regions that is well adapted for growth in sandy soils and drought conditions. E.

Variation of Residual Sexuality Rates along Reproductive Development in Apomictic Tetraploids of Paspalum

open access: yesPlants, 2022
Most apomictic plants are facultative, maintaining the ability to reproduce sexually at different frequencies depending on the taxa, ploidy, and reproductive stage.

Apomixis and strategies to induce apomixis to preserve hybrid vigor for multiple generations [PDF]

open access: yesGM Crops & Food, 2020
Hybrid seeds of several important crops with supreme qualities including yield, biotic and abiotic stress tolerance have been cultivated for decades. Thus far, a major challenge with hybrid seeds is that they do not have the ability to produce plants with the same qualities over subsequent generations.

Increased apomixis expression concurrent with genetic and epigenetic variation in a newly synthesized Eragrostis curvula polyploid [PDF]

open access: yes, 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

Apomixis frequency under stress conditions in weeping lovegrass (Eragrostis curvula). [PDF]

open access: yesPLoS ONE, 2017
To overcome environmental stress, plants develop physiological responses that are triggered by genetic or epigenetic changes, some of which involve DNA methylation.
