Quantitative analysis of transcript accumulation from genes duplicated by polyploidy using cDNA-SSCP.
Repeated rounds of polyploidy have been commonplace in the lineages leading to modern eukaryotic genomes, giving rise to widespread gene duplication. Genes duplicated by polyploidy, or "homoeologs," may continue to be expressed at equal levels following polyploidization or their expression may be dramatically altered. In this report, we describe how SSCP analysis of RT-PCR products can be used ...
متن کاملFunctional divergence of duplicated genes formed by polyploidy during Arabidopsis evolution.
To study the evolutionary effects of polyploidy on plant gene functions, we analyzed functional genomics data for a large number of duplicated gene pairs formed by ancient polyploidy events in Arabidopsis thaliana. Genes retained in duplicate are not distributed evenly among Gene Ontology or Munich Information Center for Protein Sequences functional categories, which indicates a nonrandom proce...
متن کاملA novel approach for characterizing expression levels of genes duplicated by polyploidy.
Studying gene expression in polyploids is complicated by genomewide gene duplication and the problem of distinguishing transcript pools derived from each of the two homeologous genomes such as the A- and D-genomes of allotetraploid Gossypium. Short oligonucleotide probes designed to specifically target several hundred homeologous gene pairs of Gossypium were printed on custom NimbleGen microarr...
متن کاملExpression Partitioning between Genes Duplicated by Polyploidy under Abiotic Stress and during Organ Development
Allopolyploidy has been a prominent mode of speciation and a recurrent process during plant evolution and has contributed greatly to the large number of duplicated genes in plant genomes [1-4]. Polyploidy often leads to changes in genome organization and gene expression [5-9]. The expression of genes that are duplicated by polyploidy (termed homeologs) can be partitioned between the duplicates ...
متن کاملGenes duplicated by polyploidy show unequal contributions to the transcriptome and organ-specific reciprocal silencing.
Most eukaryotes have genomes that exhibit high levels of gene redundancy, much of which seems to have arisen from one or more cycles of genome doubling. Polyploidy has been particularly prominent during flowering plant evolution, yielding duplicated genes (homoeologs) whose expression may be retained or lost either as an immediate consequence of polyploidization or on an evolutionary timescale....
