Characterization and expression analysis of somatic embryogenesis receptor kinase (SERK) genes in sexual and apomictic paspalum notatum
Podio, Maricel; Felitti, Silvina Andrea; Siena, Lorena Adelina; Delgado Benarroch, Luciana; Mancini, Micaela; Seijo, José Guillermo; González, Ana María; Pessino, Silvina Claudia; Ortíz, Juan Pablo Amelio (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 ... -
First insight into divergence, representation and chromosome distribution of reverse transcriptase fragments from L1 retrotransposons in peanut and wild relative species
Samoluk, Sergio Sebastián; Robledo, Germán Ariel; Podio, Maricel; Chalup, Laura María Isabel; Ortíz, Juan Pablo Amelio; Pessino, Silvina Claudia; Seijo, José Guillermo (Springer, 2015)Peanut is an allotetraploid (2n = 2x = 40, AABB) of recent origin. Arachis duranensis and A. ipaënsis, the most probable diploid ancestors of the cultigen, and several other wild diploid species with different genomes (A, ... -
Genética y localización del locus de la apomixis en especies del grupo Plicatula de Paspalum L. reveladas por técnicas moleculares
Aguilera, Patricia Mabel (Universidad Nacional del Nordeste. Facultad de Ciencias Agrarias, 2013)Apomixis is a mode of asexual reproduction through seeds that originate progeny that is genetically identical to the mother plant. It is significant in the subfamily Panicoideae and genera Paspalum and its importance is ... -
Harnessing apomictic reproduction in grasses : what we have learned from paspalum
Ortíz, Juan Pablo Amelio; Quarin, Camilo Luis; Pessino, Silvina Claudia; Acuña, Carlos Alberto; Martínez, Eric Javier; Espinoza, Francisco; Hojsgaard, Diego Hernán; Sartor, María Esperanza; Cáceres, María Emilia; Pupilli, Fulvio (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 ... -
Hybridity and autopolyploidy increase the expressivity of apospory in diploid paspalum rufum
Delgado, Luciana; Sartor, María Esperanza; Espinoza, Francisco; Soliman, Mariano; Galdeano, Florencia; Ortíz, Juan Pablo Amelio (Springer Wien, 2016)Paspalum rufum Nees is a perennial grass that forms a multiploid complex. Natural populations are composed mainly of diploid (2n = 2x = 20) and tetraploid (2n = 4x = 40) cytotypes. The diploid form is sexual and highly ... -
In vitro plant regeneration of spartina argentinensis parodi
Bueno, Mirian Susana; Sorrequieta, Juan Ignacio; Feldman, Susana Raquel; Ortíz, Juan Pablo Amelio (Universidad Nacional de Colombia. Instituto de Biotecnología, 2012)Spartina argentinensis Parodi es la especie dominante en comunidades halófitas que ocupan alrededor de 20.000 km2 en la Provincia de Santa Fe, Argentina. El objetivo de este trabajo fue desarrollar un método simple para ... -
Inheritance of aposporous apomixis in interspecific hybrids derived from sexual paspalum plicatulum and apomictic paspalum guenoarum
Aguilera, Patricia Mabel; Galdeano, Florencia; Quarin, Camilo Luis; Ortíz, Juan Pablo Amelio; Espinoza, Francisco (Crop Science Society of America, 2015)Apomictic Paspalum plicatulum Michx. and P.guenoarum Arechav. are promising candidates for forage grass development in tropical regions. From a plant breeding perspective, apomixis provides a unique mechanism for developing ... -
Sequence characterization, in silico mapping and cytosine methylation analysis of markers linked to apospory in paspalum notatum
Podio, Maricel; Rodríguez, María Pía; Felitti, Silvina Andrea; Stein, Juliana; Martínez, Eric Javier; Siena, Lorena Adelina; Quarin, Camilo Luis; Pessino, Silvina Claudia; Ortíz, Juan Pablo Amelio (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 ... -
Transcriptome analysis of seed development in apomictic Paspalum notatum
Felitti, Silvina Andrea; Acuña, Carlos Alberto; Ortíz, Juan Pablo Amelio; Quarin, Camilo Luis (Ricardo Antunes Azevedo, 2015-01-01)The seed developmental process involves various tissues with several ploidy levels and different genetic origins. Therefore, its characterisation at the transcriptome level is certainly a challenge. The hypothesis of ... -
Transference of eheat expressed sequence tag-simple sequence repeats to paspalum species and cross-species amplification of paspalum notatum simple sequence repeats : potential use in phylogenetic analysis and mapping
Siena, Lorena Adelina; Sartor, María Esperanza; Quarin, Camilo Luis; Espinoza, Francisco; Ortíz, Juan Pablo Amelio (Crop Science Society of America, 2014-11-12)The genus Paspalum L. includes numerous species of agronomic importance. The objectives of this work were to evaluate the transferability and polymorphism of publicly available wheat (Triticum aestivum L.) expressed sequence ...
