Targeted genome editing in polyploids: lessons from Brassica
Frontiers in Plant Science, 2023 CRISPR-mediated genome editing has emerged as a powerful tool for creating targeted mutations in the genome for various applications, including studying gene functions, engineering resilience against biotic and abiotic stresses, and increasing yield and ...

Synaptonemal complex formation in Avena polyploids [PDF]
Heredity, 1989 Avena maroccana (2n = 4x = 28) and A. sativa (2n = 6x = 42) are allopolyploids. Reconstructions from electron micrographs of synaptonemal complexes in serial sections of pollen mother cells showed that associations at zygotene and subsequent stages of meiosis are confined to homologous chromosomes only, with the result that only bivalents are generated.

Polyploidy breaks speciation barriers in Australian burrowing frogs Neobatrachus [PDF]
, 2020 Polyploidy has played an important role in evolution across the tree of life but it is still unclear how polyploid lineages may persist after their initial formation.

Next‐generation polyploid phylogenetics: rapid resolution of hybrid polyploid complexes using PacBio single‐molecule sequencing [PDF]
New Phytologist, 2016 Summary Difficulties in generating nuclear data for polyploids have impeded phylogenetic study of these groups. We describe a high‐throughput protocol and an associated bioinformatics pipeline (Pipeline for Untangling Reticulate Complexes (Purc)) that is able to generate these data quickly and conveniently, and demonstrate its efficacy on accessions ...

Untangling Complex Histories of Genome Mergings in High Polyploids [PDF]
Systematic Biology, 2007 Polyploidy, the duplication of entire genomes, plays a major role in plant evolution. In allopolyploids, genome duplication is associated with hybridization between two or more divergent genomes. Successive hybridization and polyploidization events can build up species complexes of allopolyploids with complicated network-like histories, and the ...

Niche divergence and limits to expansion in the high polyploid Dianthus broteri complex [PDF]
, 2019 Niche evolution in plant polyploids remains controversial and evidence for alternative patterns has been reported. Using the autopolyploid Dianthus broteri complex (2×, 4×, 6× and 12×) as a model, we aimed to integrate three scenarios – competitive ...

Molecular evidence for multiple polyploidization and lineage recombination in the Chrysanthemum indicum polyploid complex (Asteraceae) [PDF]
New Phytologist, 2006 The Chrysanthemum indicum polyploid complex comprises morphologically differentiated diploids, tetraploids and hybrids between C. indicum and C. lavandulifolium. The relationships between species and cytotypes within this complex remain poorly understood.
