Reproduction mode and apospory expressivity of selected hybrids of Paspalum notatum Flügge [PDF]
, 2021 Paspalum notatum Flüggé (bahiagrass) is the most important forage grass in the native grasslands of southern Brazil; the native germplasm is tetraploid and apomictic.

In Silico and Fluorescence In Situ Hybridization Mapping Reveals Collinearity between the Pennisetum squamulatum Apomixis Carrier-Chromosome and Chromosome 2 of Sorghum and Foxtail Millet. [PDF]
PLoS ONE, 2016 Apomixis, or clonal propagation through seed, is a trait identified within multiple species of the grass family (Poaceae). The genetic locus controlling apomixis in Pennisetum squamulatum (syn Cenchrus squamulatus) and Cenchrus ciliaris (syn Pennisetum ...

Tetraplioid races of Paspalum notatum show polysomic inheritance and preferential chromosome pairing around the apospory-controlling locus [PDF]
, 2004 The objective of this work was to determine the type of inheritance (disomic/polysomic) in tetraploid (2n=4x=40) Paspalum notatum and investigate the transmission pattern of the chromosome region associated with apospory. An F1 family segregating for the

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.

Frontiers in Plant Science, 2018 Apomixis is a clonal mode of reproduction via seeds, which results from the failure of meiosis and fertilization in the sexual female reproductive pathway. In previous transcriptomic surveys, we identified a mitogen-activated protein kinase kinase kinase

Apospory and parthenogenesis may be uncoupled in Poa pratensis L.: cytological and genetic evidences
, 2001 Despite the potential that apomixis has for ag- riculture, there is little information regarding the genetic control of its functional components. We carried out a cytohistological investigation on an F1 segregating popu- lation of Poa pratensis obtained

Plant Science TodayApospory, the direct development of gametophytes from somatic sporophytic tissue, represents a rare and intriguing deviation from the typical fern life cycle. We report the first confirmed instance of apospory in Pteris quadriaurita Retz.

Plant Breeding, Volume 145, Issue 3, Page 561-574, June 2026.ABSTRACT This study estimated the repeatability of forage traits in 84 Paspalum nicorae ecotypes using six statistical methods and quantified the minimum number of harvests needed for effective selection. Multivariate analyses based on best linear unbiased prediction (BLUP) values were also performed to assess genetic variability, identify key traits ...
