WebJul 17, 2024 · As summarized in a recent review on cytonuclear responses to genome doubling (Sharbrough et al., 2024), there are a number of potential mechanisms to maintain cytonuclear stoichiometry in polyploid plants. Elevated nuclear gene copy numbers resulting from whole-genome duplications (WGD) could be compensated by (a) more … WebApr 6, 2024 · Prunus is an economically important genus widely distributed in the temperate Northern Hemisphere. Previous studies on the genus using a variety of loci yielded conflicting phylogenetic hypotheses. Here, we generated nuclear reduced representation sequencing data and plastid genomes for 36 Prunus individuals and two outgroups. Both …

WebJul 26, 2024 · In polyploids, doubling of the nuclear genome may add challenges to maintaining balanced expression of proteins involved in cytonuclear interactions. Here, we use ribo-depleted RNA sequencing (RNA-seq) to analyze transcript abundance for nuclear and organellar genomes in leaf tissue from four different polyploid angiosperms and their … WebMar 12, 2024 · Its genome has been sequenced multiple times, but A and B subgenomes could not be separated because no published genome for E. indica existed. ... Subgenomic dominance may be driven by the effects of cytonuclear interacting genes. ... Cytonuclear responses to genome doubling. Am J Bot. 2024;104:1277–80. Article CAS PubMed … earth centric view
The Role of Hybridization in Plant Speciation Annual Review of …
WebWhereas allopolyploidy (i.e., resulting from hybridization and genome doubling) has long been recognized as an important mode of plant speciation, the implications of genome duplication have typically not been taken into account in most fields of plant biology. ... Figure 2: The growth response to salinity stress occurs in two phases: a rapid ... WebDoubling of the nuclear genome via polyploidy may further complicate the challenge of coordinating cytonuclear expression, as it has the potential to perturb the ratio of nuclear to organel-lar genome copies (22, 23). It appears that nuclear genome dou-bling elicits at least a partial compensatory increase in organellar WebFeb 1, 2024 · The diploid D-genome lineage of the Triticum/Aegilops complex has an evolutionary history involving genomic contributions from ancient A- and B/S-genome species. We explored here the possible cytonuclear evolutionary responses to this history of hybridization. Phylogenetic analysis of chloroplast DN … c# test for exception
