A common set of markers that show linkage with apomIXis in all three Paspalum species define a portion of the apomixis-controlling locus that is likely to contain genes critical for apomictic reproduction. Expand

Results indicate that an unexpressed gene(s) for apomixis exists at the diploid level of bahiagrass and the expression of the trait is ploidy-dependent. Expand
Cytogenetics and Reproductive Behavior of Different Chromosome Races in Six Paspalum Species
Etude cytologique et potentiel d'utilisation dans un programme d'hybridation d'accessions de P. haumanii, P. rufum et P. maculosum. Expand
Evolutionary implications of meiotic chromosome behavior, reproductive biology, and hybridization in 6x and 9x cytotypes of Andropogon gerardii (Poaceae).
Indistinguishable exomorphology, intermixing in natural populations, and compatibility suggest that Andropogon gerardii is best understood as a cytotypically complex single species. Expand
Harnessing apomictic reproduction in grasses: what we have learned from Paspalum.
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… Expand
Genetic characterization of apospory in tetraploid Paspalum notatum based on the identification of linked molecular markers
This work found that the RFLP probe C1069, mapping to the telomeric region of the long arm of rice chromosome 12, was one of the molecular markers completely linked to apospory in P. simplex. Expand
Inheritance of apospory in bahiagrass, Paspalum notatum.
None of the apospory-free F1s segregated for the aPOSpory trait indicating that it is most likely a dominant character, however, the observed results fit better a modified model: tetrasomic inheritance of a single dominant gene with pleiotropic effect and incomplete penetrance. Expand
A comprehensive analysis of gene expression alterations in a newly synthesized Paspalum notatum autotetraploid
The authors' results show evidence for gene expression alterations occurring immediately after polyploidization in Paspalum. Expand
Mode of Reproduction of Colchicine‐Induced Paspalum plicatulum Tetraploids
Embryological analysis and progeny tests using molecular markers revealed that both induced tetraploid plants reproduced sexually and retained the high self-incompatibility system of the diploids, but set seed after reciprocal crosses and when crossed with pollen of apomictic 4x P. plicatulum.
