Abstract Background The BOP (Bambusoideae, Oryzoideae, and Pooideae) clade of the
Poaceae has a common ancestor, with similarities to the genomes of rice, Oryza sativa (2 n …

Background Karyotype, as a basic characteristic of species, provides valuable information
for fundamental theoretical research and germplasm resource innovation. However …

Key message Homoeolog expression bias and the gene dosage effect induce
downregulation of genes on chromosome A7, causing a significant increase in the plant …

Hybridization blurs species boundaries and leads to intertwined lineages resulting in
reticulate evolution. Polyploidy, the outcome of whole genome duplication (WGD), has more …

Abstract The Modern Synthesis, a pillar in biological thought, united Darwin's species origin
concepts with Mendel's laws of character heredity, providing a comprehensive …

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) …

Abstract “Synthetic” allopolyploids recreated by interspecific hybridization play an important
role in providing novel genomic variation for crop improvement. Such synthetic …

The gene balance hypothesis proposes that selection acts on the dosage (ie copy number)
of genes within dosage-sensitive portions of networks, pathways, and protein complexes to …

Key message We developed an array of Zea–Tripsacum tri-hybrid allopolyploids with
multiple ploidies. We unveiled that changes in genome dosage due to the chromosomes …

Plant polyploidization increases the complexity of epigenomes and transcriptional
regulation, resulting in genome evolution and enhanced adaptability. However, few studies …
