Meiotic recombination is a key biological process in plant evolution and breeding, as it
generates genetic diversity in each generation through the formation of crossovers (COs) …

Long terminal repeat retrotransposons (LTR‐RT s) represent a major fraction of plant
genomes, but processes leading to transposition bursts remain elusive. Polyploidy …

Despite newly formed polyploids being subjected to myriad fitness consequences, the
relative prevalence of polyploidy both contemporarily and in ancestral branches of the tree …

Natural structural variants of regulatory proteins causing quantitative phenotypic
consequences have not been reported in plants. Herein, we show that 28 natural structural …

Key message The presence of homologous subgenomes inhibited unreduced gamete
formation in wheat× Aegilops interspecific hybrids. Unreduced gamete rates were under the …

Polyploidy and natural hybridization are considered as two major evolutionary processes
involved in plant speciation and diversification. In conifers, natural hybridization has been …

Polyploidy is thought to be an evolutionary and systematic mechanism for gene flow and
phenotypic advancement in flowering plants. It is a natural phenomenon that promotes …

The maintenance of species integrity despite pervasive hybridization is ruled by the interplay
between reproductive barriers. Endogenous postzygotic isolation will shape the patterns of …

Abstract Key message Multiple QTLs control unreduced pollen production in potato. Two
major-effect QTLs co-locate with mutant alleles of genes with homology to AtJAS, a known …

Compared to diploid species, allopolyploid crop species possess more complex genomes,
higher productivity, and greater adaptability to changing environments. Next generation …
