Characterization and expression analysis of somatic embryogenesis receptor kinase (SERK) genes in sexual and apomictic paspalum notatum
(Plant Molecular Biology, 2014)The SOMATIC EMBRYOGENESIS RECEPTOR- LIKE KINASE (SERK) gene plays a fundamental role in somatic embryogenesis of angiosperms, and is associated with apomixis in Poa pratensis. The objective of this work was to ... -
Clasificación reproductiva de familias híbridas (F1) y generación de una población sexual sintética en Paspalum notatum
(Universidad Nacional del Nordeste. Secretaria General de Ciencia y Técnica, 2013-06-12)Paspalum notatum Fluggé es una gramínea perenne nativa del continente americano. Su área de distribución natural se extiende desde el centro de México hasta el centro de Argentina. Se trata de una especie utilizada como ... -
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 ... -
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 ... -
Genetic transfer from several apomictic tetraploid paspalum species to an elite group of sexual plants
(Crop Science Society of America, 2020)Basic findings from classical genetic studies are available for exploiting apomixis in the breeding of several forage grass genera. Most Paspalum species are multi- ploid with a sexual diploid cytotype and conspecific ... -
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 ... -
Interspecific hybrids between Paspalum plicatulum and P. oteroi: a key tool for forage breeding
(Universidade de São Paulo, 2016-08)Grama-tio-pedro (Paspalum oteroi Swallen) is a rare stoloniferous grass of the Plicatula group of Paspalum, well adapted to continuous grazing in areas subject to seasonal flooding in the Pantanal region, in central western ... -
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 ... -
Los sistemas genéticos en poblaciones de complejos agámicos del género Paspalum
(Universidad Nacional del Nordeste. Facultad de Ciencias Agrarias, 2011-03-22)Paspalum es uno de los géneros de gramíneas que cuenta con un gran número de especies distribuidas naturalmente en las regiones cálidas del continente americano. El género se caracteriza por presentar especies diploides de ... -
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. ...
