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 ...
Agronomic characterization of paspalum atratum swallen and P. lenticulare kunthCaracterización agronómica de paspalum atratum swallen y paspalum lenticulare kunth
(International Center for Tropical Agriculture (CIAT), 2018-05-31)
Paspalum atratum and P. lenticulare are perennial grasses, native to South America. The objective was to evaluate seasonal growth, frost tolerance, cattle preference, nutritional characteristics, seed yield and germination ...
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
(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 ...
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 ...
Transcriptome analysis of seed development in apomictic Paspalum notatum
(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 ...
Relative DNA content in diploid, polyploid, and multiploid species of Paspalum (Poaceae) with relation to reproductive mode and taxonomy
(Springer, 2016-03-10)
It is generally accepted that polyploids have downsized basic genomes rather than additive values with respect to their related diploids. Changes in genome size have been reported in correlation with several biological ...
Hybridization and heterosis in the plicatula group of paspalum
(Springer, 2017)
Most forage cultivars released for thegenus Paspalum belong to a section named Plicatula.The species of Plicatula are mostly apomictic andconsequently the genetic diversity is locked for theirgeneticimprovement. The ...
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. ...
Identification of Genes Related to Endosperm Balance Number Insensitivity in Paspalum notatum
(Crop Science Society of America, 2018-02)
The endosperm balance number (EBN) theory states that genomic contribution ratio should be kept at maternal/paternal (m:p) ratio for normal endosperm development. However, the endosperm formation in apomictic Paspalum ...
