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 regions by chromosome walking and perform an in silico mapping analysis in rice and maize. The methylation status of two apospory-related(More)
We analyzed anaphase I configurations and pollen viability in aposporous and sexual tetraploid (2n = 4x = 40) cytotypes of Paspalum notatum. Five natural aposporous accessions and three experimentally obtained sexual individuals were used. In addition, 16 (8 aposporous and 8 sexual) F1 hybrids, previously classified by their mode of reproduction, were(More)
Tetraploid (2n = 4x = 40) races of Paspalum notatum Flüggé are important natural forage grasses for the tropical and subtropical areas of the Americas. Almost all natural accessions reproduce by obligate aposporous apomixis. Previous work on the species allowed the identification of several molecular markers completely linked to apospory, one component of(More)
