Chromoanagenesis is a single catastrophic event that involves, in most cases, localized
chromosomal shattering and reorganization, resulting in a dramatically restructured …

In order to better understand the mechanisms generating genetic diversity in the recent
allotetraploid species Coffea arabica, here we present a chromosome-level assembly …

Aneuploidy is a cellular state with an unbalanced chromosome number that deviates from
the usual euploid status. During evolution, elaborate cellular mechanisms have evolved to …

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 …

Elymus nutans Griseb. is an important herbage for forage and ecological restoration in the
Qinghai‐Tibet Plateau (QTP). It is widely distributed in different habitats of the QTP and has …

We profiled the global gene expression landscape across the reproductive lifecycle of
Brassica napus. Comparative analysis of this nascent amphidiploid revealed the …

Background Unreduced gamete formation during meiosis plays a critical role in natural
polyploidization. However, the unreduced gamete formation mechanisms in Triticum …

Synthetic hexaploid wheat offers breeders ready access to potentially novel genetic
variation in wild ancestral species. In this study, we crossed MY3478 (2 n= 4 x= 28, AABB) …

Aneuploidy generally has severe phenotypic consequences. However, the molecular basis
for this has been focused on single chromosomal dosage changes. It is not clear how the …
