Polyploidy, which arises from genome duplication, has occurred throughout the history of
eukaryotes, though it is especially common in plants. The resulting increased size …

Allopolyploids result from hybridization between different evolutionary lineages coupled with
genome doubling. Homoeologous chromosomes (chromosomes with common shared …

Plant cytogenetic studies have provided essential knowledge on chromosome behavior
during meiosis, contributing to our understanding of this complex process. In this review, we …

Hybridization and polyploidy have been considered as significant evolutionary forces in
adaptation and speciation, especially among plants. Interspecific gene flow generates novel …

Many species, including most flowering plants, are polyploid, possessing multiple genomes.
During polyploidisation, fertility is preserved via the evolution of mechanisms to control the …

During crop domestication and breeding, wild plant species have been shaped into modern
high-yield crops and adapted to the main agro-ecological regions. However, climate change …

Canola is an important oilseed crop, providing food, feed, and fuel around the world.
However, blackleg disease, caused by the ascomycete Leptosphaeria maculans, causes …

Meiosis is a key feature of sexual reproduction. During meiosis homologous chromosomes
replicate, recombine, and randomly segregate, followed by the segregation of sister …

Newly formed polyploids often show extensive meiotic defects, resulting in aneuploid
gametes, and thus reduced fertility. However, while many neopolyploids are meiotically …

Allopolyploids have globally higher fitness than their diploid progenitors; however, by
comparison, most resynthesized allopolyploids have poor fertility and highly unstable …
