DOI: 10.1002/ajb2.16133
Abstract: PREMISE Whole genome duplication is considered a major mechanism of sympatric speciation due to the creation of strong and instantaneous reproductive barriers. Although post-zygotic reproductive isolation between diploids and polyploids is often expected, the extent… read more here.

DOI: 10.1016/j.sajb.2018.09.018
Abstract: Abstract Microsporogenesis studies in Brachiaria have been concentrated in the species B. ruziziensis, B. decumbens and B.brizantha and hybrids because they have great importance as forage. Besides the sexual behavior, B. ruziziensis is among a… read more here.

DOI: 10.1038/s41598-019-48639-7
Abstract: The genus Avena (oats) contains diploid, tetraploid and hexaploid species that evolved through hybridization and polyploidization. Four genome types (named A through D) are generally recognized. We used GBS markers to construct linkage maps of… read more here.

DOI: 10.1371/journal.pone.0195054
Abstract: Polyploidization has played an important role in the evolution of vertebrates, particularly at the base of Teleostei–an enormously successful ray-finned fish group with additional genome doublings on lower taxonomic levels. The investigation of post-polyploid genome… read more here.

DOI: 10.3389/fnut.2022.1034751
Abstract: Artificial induction of polyploidy is an efficient technique for improving biological properties and developing new varieties of many plants. In this study, we analyzed and compared differences in characteristics (morphological and biological) of diploid and… read more here.
