Apospory and parthenogenesis may be uncoupled in Poa pratensis L.: cytological and genetic evidences
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

Tetraploid races of Paspalum notatum show polysomic inheritance and preferential chromosome pairing around the apospory-controlling locus [PDF]
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

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

Seasonal Expression of Apospory in Bahiagrass [PDF]
Flowering plants can reproduce sexually (outcrossing and/or selfing) and/or asexually. Sexual reproduction implies the successful completion of meiosis and double fertilisation for the formation of both the embryo and the endosperm.

Disclosing the Molecular Link between Apospory and Diplospory
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.

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 ...
