Environmental and Genetic Factors Affecting Apospory Expressivity in Diploid Paspalum rufum [PDF]
Plants, 2021 In angiosperms, gametophytic apomixis (clonal reproduction through seeds) is strongly associated with polyploidy and hybridization. The trait is facultative and its expressivity is highly variable between genotypes.

Differential Epigenetic Marks Are Associated with Apospory Expressivity in Diploid Hybrids of Paspalum rufum [PDF]
Plants, 2021 Apomixis seems to emerge from the deregulation of preexisting genes involved in sexuality by genetic and/or epigenetic mechanisms. The trait is associated with polyploidy, but diploid individuals of Paspalum rufum can form aposporous embryo sacs and ...

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

The Auxin-Response Repressor IAA30 Is Down-Regulated in Reproductive Tissues of Apomictic Paspalum notatum [PDF]
Plants, 2022 The capacity for apomixis in Paspalum notatum is controlled by a single-dominant genomic region, which shows strong synteny to a portion of rice chromosome 12 long arm.

Diploid aposporous sunflower forms triploid BIII progeny displaying increased apospory levels and non-random genetic mutations [PDF]
Scientific ReportsApomixis (asexual reproduction via seeds) has the potential to revolutionize sunflower breeding. In previous studies, we identified a diploid sunflower line (Rf975) that naturally exhibits extra gametophytes resembling aposporous apomictic embryo sacs ...

Apospory and Diplospory in Diploid Boechera (Brassicaceae) May Facilitate Speciation by Recombination-Driven Apomixis-to-Sex Reversals [PDF]
Frontiers in Plant Science, 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 ...

Seasonal expression of apospory in bahiagrass
Tropical Grasslands-Forrajes Tropicales, 2013 Flowering plants can reproduce sexually (outcrossing and/or selfing) and/or asexually. Sexual reproduction implies the successful completion of meiosis and double fertilization for the formation of both the embryo and the endosperm. In contrast, gametophytic apomixis is an asexual mode of reproduction through seeds, that in-volves parthenogenetic ...

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

Construction of AFLP-based cosegregation groups of tetraploid Plicatula species and identification of markers linked to apomixis [PDF]
Rodriguésia, 2022 Most species of Plicatula are important native forages. This work aimed to build framework cosegregation groups of the apomictic tetraploid race of Paspalum guenoarum cv. Rojas and localize the locus controlling apomixis in the species.

Cyto-Embryological Analysis of Wild Kentucky Bluegrass Germplasm in Gansu Province, China
Agronomy, 2023 Reproduction studies, particularly embryology, represent basic information of any plant. However, the current embryological information is fragmentary for Kentucky bluegrass (Poa pratensis L.).
