EVOLUTIONARY DYNAMICS OF AUTOPOLYPLOIDS IN NATURAL POPULATIONS: THE CASE OF TURNERA SIDOIDES COMPLEX [PDF]
Turnera sidoides (x=7) is one of the few well-studied South American autopolyploid complexes. Since polyploidy has played a prominent role within this complex, ongoing studies in T.

A Trojan horse inside the gates: Alien-native mating interactions in mixed populations of Solidago taxa. [PDF]
DAPI flow cytometry identified post‐invasion processes—hybridisation, introgression, and polyploidization—in mixed populations of Solidago canadensis, S. virgaurea and S. ×niederederi. Abstract The establishment and possible impacts of alien–native hybrids depend on their formation frequency and ability to spread using generative and vegetative ...

Substantial non-homologous recombination and structural variation results from Brassica AABC and CCAB hybrid meiosis. [PDF]
SUMMARY Meiotic crossovers contribute to genetic diversity and play a crucial role in homologous chromosome segregation. Non‐homologous crossovers in Brassica, involving the exchange of genetic material between genomes, can be valuable for transferring novel traits or characteristics between Brassica species.

Multiple hybrid zones involving four Cardamine species and their triploid progeny: watching allopolyploid speciation in action? [PDF]
Summary Hybrid zones provide excellent opportunities to study evolutionary processes linked to interspecific gene flow, including introgression, genetic erosion, polyploid establishment, and speciation. The genus Cardamine (Brassicaceae) serves as an excellent model for polyploid evolution, including one of the few well‐documented neo‐allopolyploid ...

Advances and Perspectives for Polyploidy Breeding in Orchids
The orchid market is a dynamic horticultural business in which novelty and beauty command high prices. The two main interests are the development of flowers, from the miniature to the large and showy, and their fragrance.

Historically, crosses between Medicago sativa (alfalfa) and M. arborea with alfalfa as the seed parent failed, as did crosses using M. arborea as the seed parent. Thus, a reproductive barrier kept the two species isolated until early in this century. The

Abnormal meiosis in an intersectional allotriploid of Populus L. and segregation of ploidy levels in 2x × 3x progeny. [PDF]
Triploid plants are usually highly aborted owing to unbalanced meiotic chromosome segregation, but limited viable gametes can participate in the transition to different ploidy levels.

Unreduced megagametophyte production in lemon occurs via three meiotic mechanisms, predominantly second-division restitution [PDF]
Unreduced (2n) gametes have played a pivotal role in polyploid plant evolution and are useful for sexual polyploid breeding in various species, particularly for developing new seedless citrus varieties.
