Tragopogon pratensis: Multiple introductions to North America, circumscription, and the formation of the allotetraploid T. miscellus

Douglas E. Soltis et al.

Summary: Tragopogon (Asteraceae) is a genus that includes two recently formed allopolyploids, T. mirus and T. miscellus, in western North America. The introduction of diploid parents, T. dubius and T. porrifolius from Europe, played a role in the formation of these allopolyploids. In this study, we focused on the introduction of the second diploid parent, T. pratensis, into North America. Our findings show that T. pratensis as currently defined is polyphyletic, with at least four major ITS types in its native range. Two of these ITS types have been introduced from Europe into North America and are widespread in Canada and the U.S.A. The formation of T. miscellus in the western North America involved only one of these ITS types. Our research suggests that not all genotypes of T. pratensis may be capable of participating in the formation of allopolyploids. Additionally, we found that there are genetically distinct entities within T. pratensis that may be considered separate species. Further research involving phylogenetic analyses, taxonomy, morphology, and cytology are needed to fully understand the complexities of T. pratensis.

Cross-compatibility in interspecific hybridization between three Prunus species

Marek Szymajda et al.

Summary: A study was conducted on interspecific cross-compatibility between different genotypes of three species in the Prunus genus. It was found that incompatibilities occur at various stages of hybridization and can affect the development of hybrid fruits and seedlings. The maternal genotype of the Japanese plum has a greater impact on fruit setting, while the paternal genotype of the apricot has a smaller effect. Seed germination and viability of hybrid seedlings depend on the interaction between parental forms. The use of specific genotypes allows for the production of more hybrids.

Tragopogon dubius: Multiple introductions to North America and the formation of the New World tetraploids

Douglas E. Soltis et al.

Summary: Tragopogon is an important model for the study of whole-genome duplication, and researchers have found that introduced T. dubius plants from Europe have formed multiple tetraploid species in North America,with repeated formation involving only one of the ITS subtypes. The study also suggests that many entities traditionally considered as T. dubius should be recognized as distinct species.
