Protein-coding genes are epigenetically regulated in Arabidopsis polyploids
Open accessAbstract
The fate of redundant genes resulting from genome duplication is poorly understood. Previous studies indicated that ribosomal RNA genes from one parental origin are epigenetically silenced during interspecific hybridization or polyploidization. Regulatory mechanisms for protein-coding genes in polyploid genomes are unknown, partly because of difficulty in studying expression patterns of homologous genes. Here we apply amplified fragment length polymorphism (AFLP)–cDNA display to perform a genome-wide screen for orthologous genes silenced in Arabidopsis suecica , an allotetraploid derived from Arabidopsis thaliana and Cardaminopsis arenosa . We identified ten genes that are silenced from either A. thaliana or C. arenosa origin in A. suecica and located in four of the five A. thaliana chromosomes. These genes represent a variety of RNA and predicted proteins including four transcription factors such as TCP3. The silenced genes in the vicinity of TCP3 are hypermethylated and reactivated by blocking DNA methylation, suggesting epigenetic regulation is involved in the expression of orthologous genes in polyploid genomes. Compared with classic genetic mutations, epigenetic regulation may be advantageous for selection and adaptation of polyploid species during evolution and development.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
