Diversity in diploid, tetraploid and mixed diploid-tetraploid populations of paspalum simplex
(Crop Science Society of America, 2013-07)
The tetraploid cytotype of Paspalum simplex has a wide geographical distribution and reproduces by apomixis, while the diploid grows in a restricted area in northern Argentina and behaves as cross-pollinated. The objective ...
Sequence characterization, in silico mapping and cytosine methylation analysis of markers linked to apospory in paspalum notatum
(Sociedade Brasileira de Genética, 2012)
In previous studies we reported the identification of several AFLP, RAPD and RFLP molecular markers linked to apospory in Paspalum notatum. The objective of this work was to sequence these markers, obtain their flanking ...
Widening the gene pool of sexual tetraploid bahiagrass : generation and reproductive characterization of a sexual synthetic tetraploid population
(Crop Science, 2018)
The improvement of bahiagrass, Paspalum notatum Flüggé, has been inhibited by reduced levels of genetic diversity in sexual tetraploid germplasm. A few experimental sexual tetraploid genotypes (ESTGs) have been generated ...
Unravelling the ambiguous reproductive biology of paspalum malacophyllum : a decades old story clarified
(Springer, 2015)
In a recent manuscript published by our group we analyzed the reproductive biology of the grass Paspalum malacophyllum by using traditional embryological techniques combined with current cytological and molecular methods. ...
Diversity in apomictic populations of Paspalum simplex Morong
(Crop Science Soc Amer, 2014)
Paspalum is considered a genetic model for studying the sources of genotypic variability and breeding techniques in apomictic plants. Paspalum simplex is a warm-season forage grass that well represents the genus since it ...
Genetic relationship among paspalum species of the subgenus anachyris : taxonomic and evolutionary implications
(Elsevier, 2014-10)
Paspalum is one of the most important genera of the Poaceae family due to its large number of species and
diversity. The subgenus Anachyris comprises six species mainly from South America grouped together by
sharing rare ...
Competition between meiotic and apomictic pathways during ovule and seed development results in clonality
(Wiley, 2013-01)
Meiotic and apomictic reproductive pathways develop simultaneously in facultative
aposporous species, and compete to form a seed as a final goal. This developmental competition
was evaluated in tetraploid genotypes of ...
Harnessing apomictic reproduction in grasses : what we have learned from paspalum
(Oxford University Press, 2013-09)
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 guarantees the perpetuation ...
