A study of Paspalum species native to South America shows that while clones can expand a plant's range, the method a parent uses to clone itself will impact how the population develops.
Clonal reproduction is a desirable trait to possess as an invasive plant and has helped Praxelis clematidea to become highly invasive around the world.
Polyploidization of the plant genome affects the phenotype of individuals including their morphology. In autopolyploids, we expect mainly nucleotypic effects, from a number of monoploid genomes (i.e. chromosome sets) or...
Asexual reproduction via seeds (apomixis) is an important speciation mechanism in angiosperms, but its frequency is largely unknown. Mráz and Zdvořák used flow cytometric seed screening to unravel reproductive pathways...
The genus Boechera (Brassicaceae) is comprised of both sexual and apomictic species, permitting comparative analyses of meiotic disturbances and parthenogenesis. Hybridization, polyploidy and environmental adaptation...
The alpine plant Ranunculus kuepferi can face spring frosts while growing reproductive organs. Does the cold explain why sometimes the plant doesn't bother with sex?
One of the features of some plants is they can be polyploid. Humans have a pair of chromosomes carrying our genetic information. Plants can vary between one or two chromosomes, known as haploid or diploid. However, they...
The underlying genetic causes of the switch to apomixes are not yet fully understood, but in Hypericum there is good evidence for the existence of ‘apomictic factors’.
Asexual reproduction is relatively common in higher plants and comprises vegetative reproduction or clonal reproduction through seeds (apomixis or agamospermy). Apomixis is found in less than 1% of angiosperms and...
Allopolyploidy combined with apomixis is a partnership that generates novel species in many plant taxa, including the genus Sorbus. Uhrinová et al. use chloroplast and nuclear markers as well as flow cytometry to reveal...
Apomixis (asexual seed formation) generates clonal plants with a maternal genotype. Apomictic Hieracium subgenus Pilosella species mitotically form female gametes, with the seed’s embryo and endosperm developing...
Polyploidization and apomixis contribute to taxonomic complexity in Anthosachne, a perennial genus native to Australia in the wheat tribe. Sha et al. performed a phylogenetic analysis to explore differentiation patterns...
In a recent article published in AoB PLANTS, Schinkel et al. present a study on geographical parthenogenesis, an enigmatic and much disputed phenomenon that involves closely related sexual and apomictic (asexually...
