Gene duplications have long been recognized as a contributor to the evolution of genes with
new functions. Multiple copies of genes can result from tandem duplication, from …

A century ago experiments with the flowering plant Datura stramonium and the fruit fly
Drosophila melanogaster revealed that adding an extra chromosome to a karyotype was …

The supernumerary B chromosome of maize is dispensable, containing no vital genes, and
thus is variable in number and presence in lines of maize. In order to be maintained in …

SUMMARY RNA‐Sequencing is widely used to investigate changes in gene expression at
the transcription level in plants. Most plant RNA‐Seq analysis pipelines base the …

The phenotypic consequences of the addition or subtraction of part of a chromosome is
more severe than changing the dosage of the whole genome. By crossing diploid trisomies …

Classic genetics studies found that genomic imbalance caused by changing the dosage of
part of the genome (aneuploidy) has more detrimental effects than altering the dosage of the …

The non‐essential supernumerary maize (Zea mays) B chromosome (B) has recently been
shown to contain active genes and to be capable of impacting gene expression of the A …

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 …

Two recent studies have addressed the long-term consequences of whole genome
duplications (WGD). Specifically, they analyzed transcriptomes of the plant Arabidopsis …

Aneuploidy can globally affect the expression of the whole genome, which is detrimental to
organisms. Dosage-sensitive regulators usually have multiple intermolecular interactions …
